These are a couple decks that we purchased from people who said it "works fine". They did actually FF, REW and move in Play mode, but that's where it ended. We knew they would need work, as inevitably all 20 to 40+ year old tape decks do have a number of things that need to be taken care of prior to being usable (typically 12-18 hours of tech time (sometimes as much as 24 and once we had one require 40 hours to do it justice) + parts), but we don't see too many in as bad a shape as these were (click above photos for details). Again these are decks that came from someone who said they "work fine"! Be careful out there when you're getting excited about bidding on that "good deal" on line @ eb_y, cra_gs_ist or other auction that say's "all functions test fine and deck works as it should". Yeah, right. Just FYI.

Email we just received from a guy that tried some 'on-line-auction seller' decks, "I am looking to resurrect my vintage SONY Reel To Reel Tapecorder,
MODEL TC353D. It was in storage since about 1987 when a 'friend' borrowed it, tried to switch speeds while in PLAY mode and jammed everything up. Last few years I've been buying some (4-5) models off ebay with most being listed as
'works' but upon receipt I found none have performed. Most of the others I have purchased all seem to have same problem...Can you help? I want to record in analog just like the old days. - T. Daley"


 
 

 
Above photo is of a Teac A-4010S having typical Main Capstan Belt change and Pinch Roller Arm re-lube operation.
Just FYI as typical of some of the work that is required to bring any 20+ year old Reel to Reel tape deck back to life, regardless of how well a person selling an old deck, that has not been recently serviced, may say it works! In fact the worst decks are commonly the units that are stated as having low hours, have been little or never used, or the worst offender "is NIB (New In Box)". While that may seem like a good thing, experience tells us that those are the "scariest" to purchase. They generally require the most work to bring back to a practical level of operation. Just like a car that has sat for many years not being used, similar "atrophy" happens to most electro-mechanical devices, ie; Turntables, Cassette Decks, 8-Tracks, VCR's, R2R's etc. Just FYI.

 Our technician has completely gone through and 'Certified' this unit.

 We have completely and extensively gone through the mechanicals and electronics of this unit.

 Transport was disassembled, and mechanical parts disassembled, cleaned, re-lubed and reassembled

 Tape Tension arms disassembled, cleaned and re-lubed, and their springs adjusted and had fresh 500,000 grade silicone lube gel applied

 pinch-roller mechanism completely disassembled, cleaned and re-lubed

 Damaged Pinch roller arm springs replaced

 PR mechanism solenoid mounts adjusted

 Capstans / flywheels removed, bushings and axels cleaned and re-lubed and flywheels burnished (see photos above)

 Capstan burnished

 Rubber pinch roller removed and re-conditioned

 Brand new #042 counter belt installed (no other belts, as it's "Direct Drive")

 Heads have been cleaned and de-magnetized as well as the entire transport.

 Brakes adjusted on fast wind modes also (optimized for 7" tape.)

 Back tension adjusted on both reel motors.

 EOT sensor adjusted

 All three motors test perfectly. Following above adjustments, Reel Start and Stop tested at beginning, middle and end of 7" tapes

 Internal pots, switches and controls cleaned and tested for noise-free function (initially, of course, had typical static / noise which is to be expected in an 'un-serviced' deck after 35+ years).

 We adjusted the VU meters mechanically and electronically w/ factory test tone tapes, as well as the internal playback levels for both directions independently and record levels.

 Specific to this deck, all the circuit board pins and connectors (and there are dozens), burnished individually with fiber-glass pen (this is a must on this deck for reliable performance)

 Both spindles in perfect alignment.

 We also adjusted the reel table heights.

 Heads in great shape as well, with many years of performance left in them.

 Playback and Record Head alignment / azimuth was adjusted for peak performance with factory test tone tape and oscilloscope.



 Speed tested to 98.6% accuracy following refurb (meaning that our 'verified' 1000Hz test tape now plays back at 986Hz).

 Adjusted to record a @ -0dB = 0dB PB (+/- 3dB) @ 1kHz on Maxell UDXL tape (Biased for same Maxell UDXL tape).

 Floor noise measured at >-60dB w/ blank tape, L&R

 This Tandberg 9100X functions, plays, and records VERY WELL (and we really put them through the paces, testing both with well mixed, recently recorded CD material and CD recorded / factory test tones looking for correct head Azimuth and speed accuracy).  (Total time investment in refurb / testing
~ 21 hours).

Face is beautiful, brushed, Stainless Steel and TEAK wood, veneer side panels all in great condition. Deck looks and works great! 


The Tandberg 9100X Stereo Reel to Reel tape deck. Ready to GO! This is one of the few reel to reel decks we get in that make it to our finished page. Great performer. If you're looking for a reel to reel deck to "actually use" here you go. Only about 25% of the used Reel decks out there can be "practically" restored to working order. This one made it through with flying colors again after
~21 hours of bench time.

The deck tests great! Looks and sounds great too! We have completely gone through it. Will play 3", 5" & 7" reels (transport best optimized for 7" reels).

Tandberg 9100X Features include:

- 4-Track / 2-Channel head stack / tape format
- 3 Heads for instant monitoring of tape levels while recordin
g (actually there's a "4th head" to handle 'bias', which is what the "Cross Field" means)
- Cross-Field Biasing (via separate head) allows for pushing levels harder, and excellent 'high frequency' performance

- 3 Motors (tech noted, "heavy duty") for trouble free performance (has a lot to do with it still being a viable piece of gear due to less rubber parts)
- Echo & Sound-on-Sound (if you're versed at using that style of recording, or educate yourself on it via the included manual)
- IC logic tape transport for "Touch" control
- Dual front mounted, BALANCED 1/4" Microphone inputs
- Analog tape counter

- Triple speeds at 7.5 ips / 19cms, 3 3/4ips / 9.5 cms &
1 7/8 ips / 4.8 cms
- Separate dual mic and line level controls AND CAN BE 'MIXED'!
- Dual, BALANCED 1/4" front mounted mic inputs
- Source / Monitor selector
- Photo-Electrical / Optical tape auto-stop for transport (best used with leaders installed on tapes)
- Edit / Cue Button (for hearing tape during 'Fast Wind')

- L & R Output level control (also controls volume to Headphones)
- Dual analog VU level meters (lit during Recording. Dark for Playback by design)
- Spring loaded tape hub spindles (no need for rubber reel retainers)
- optional wired remote port on rear panel (remote not included)


As stated earlier we have completely gone through it cleaning heads and all else, lubing, adjusting, reconditioning pinch rollers and other rubber parts, demagnetizing heads and entire transport and testing everything. Tape speed tested and resulted in 98.6% accuracy using a 1000 Hz test tape. Plays and records Exceptionally well (and we really put them through the paces, testing both with well mixed CD material and CD test tones looking for correct head Azimuth, tape speed accuracy and making test recordings). Pinch rollers and heads all in GREAT condition!!! Face is made of beautiful, brushed, stainless steel and looks great. Very clean and looks near new. Unit looks GREAT!

Of the many Reel to Reel Tape decks built by Sony, especially from the late 1960s and into the early 70s, this has always been one of our favorite machines for Features, Build quality (that by luck, lends itself well to restoration 50 years later), solid and most importantly DEPENDABLE performance, and consistent sound quality.

 
 Our technician has completely gone through and 'Certified' this unit.

 Entire transport was disassembled down to the chassis, and every mechanical part including head block assembly, was cleaned of "varnished" lubes and re-lubed as well as the always at issue on most Sony's of this era, Pinch Roller plunge assembly, re-lubed and reassembled.

 All Drive and counter belts replaced for trouble-free service. Rubber pinch roller has been reconditioned, as well as all three internal drive tires / wheels for positive grip, capstan burnished.

 Supply (left) reel spindle lock replaced from another unit we purchased for that and a couple other parts as the original had a small, almost invisible crack in it.

 Both reel hubs / clutches removed, disassembled and cleaned.

 All hub brake pads have been replaced, and their bearings re-lubed and adjusted on fast wind modes also.

 Motor has been re-lubed as well.

 Internal voltage is self regulated DC and values were verified.

 All Internal & External pots, controls, & switches (including the linear 'record' switches) cleaned and tested for noise-free function.

 Both spindles in perfect alignment (originally were not, and were off a few degrees from perpendicular).

 We also adjusted the reel table heights for no "reel rub".

 Pinch roller reconditioned / re-surfaced.

 Initial 'less than stellar' recording performance on one side was traced down to a bad, 19V Zener diode on the power supply board, causing it to supply ~5V instead of it's intended +25VDC. Once replaced, we had full voltage to the record amplifier and was then able to adjust record amp to intended levels.

 New VU meter illumination lamp installed and both record indicator lamps test fine.

 Internal 'Bias', 'Record-Level', 'Record EQ' and 'PB' micro-pots cleaned EXTENSIVELY and levels adjusted with proper test tapes.



 Heads were cleaned and de-magnetized as well as the entire transport.

 Ferrite and Ferrite heads all in great shape, with many years of performance left in them. (technicians note: "heads appear 'un-used'. They're the best we've ever had on a deck and look NEW!")

 Head alignment / azimuth has been checked for peak performance with factory test tone tape and oscilloscope at 100Hz, 1kHz and 10kHz.

 Both level meters adjusted for even playback level w/ factory test tone tape.

 Floor noise tested to -60Dbm w/ fresh, blank tape on PB.

 Entire face plate replaced with a cleaner example from a donor unit as well as the originally scratched / scuffed head cover

 Plays and Records GREAT @ 0dB / 1kHz on High Bias tape (Maxell UDXL).


 Speed checked once 'warmed up', to 98.23% accuracy. (Meaning a 'factory' 1kHz tape plays back at 1018Hz. The last on of these we had in 2014 tested to just over 95% accuracy, which is just at the limit of passing our bar) (tech note: has Sony #0 motor / belt pulley installed from factory)

 Following the above procedures, entire unit was detailed inside and out

Again, Pinch roller and Heads all in GREAT condition.

(Total time investment in refurb / testing
~ 21 hours).
Cosmetically in fabulous condition!

Again, following the above stated bench work / testing, our technician has 'Certified' this deck and it is an great performer sonically and mechanically. This deck has had typical restoration. It's pretty much had the clock rolled back 45+ years on it. With the exception of a couple small veneer chips on the two, front, lower edges, and 'light' scuffing from the perimeter of a previously installed metal reels on the face, (see photos above {the reel scuffs don't really show up for photos}) the units looks fabulous. Again, over and above our standard restoration, this deck has virtually NEW heads!

Of the many Reel to Reel Tape decks built by Sony, especially from the late 1960s and into the early 70s, this has always been one of our favorite machines for Features, Build quality (that by luck, lends itself well to restoration 50 years later), solid and most importantly DEPENDABLE performance, and consistent sound quality.

 
 Our technician has completely gone through and 'Certified' this unit.

 Entire transport was disassembled down to the chassis, and every mechanical part including head block assembly, was cleaned of "varnished" lubes and re-lubed as well as the always at issue on most Sony's of this era, Pinch Roller plunge assembly, re-lubed and reassembled.

 All Drive and counter belts replaced for trouble-free service. Rubber pinch roller has been reconditioned, as well as all three internal drive tires / wheels for positive grip, capstan burnished.

 "SERVICE DETAILS" COMING...

As stated earlier our technician noted that the heads were in essentially new condition. He further stated on the work sheet, "overall, the deck shows little use, and was remarkably, actually functional prior to tear down." (a 45 year old deck that still functions prior to a restoration, would be classified as "remarkable")

Again, following the above stated bench work / testing, our technician has 'Certified' this deck and it is an great performer sonically and mechanically. This deck has had typical restoration. It's pretty much had the clock rolled back 45+ years on it. With the exception of a small veneer chip on the front, right, lower corner, (see photos above) the units looks fabulous. Again, over and above our standard restoration, this deck has virtually NEW heads!
Machine is READY TO GO! Would make a great deck for any one needing a deck to do tape to CD or Hard Drive transfers of reel to reel tapes or for making NEW reel tape recordings. Comes with an 'e' copy / pdf of the Sony TC-377 owners / users manual. Includes a take-up reel. Includes our standard 90 day limited warranty.

A few random notes about head / track format for 'consumer' / 'semi-pro' 1/4 & 1/2" reel to reel machines:

Most 'consumer' decks will utilize a "4-Track / 2-Channel" track / head format. That means the tape will have '2-sides' and generally be 'stereo'. With the exception of 'portable' decks, many decks made / sold from the early-mid 1960's and, most from the late 1960's thru the last models in the early 1990's will be this format. Most decks will feature two speeds; 3 3/4 ips and 7.5 ips. Some early decks (early 1960's to early 1970's) will also have a very slow speed of 1 7/8 ips. That speed was generally used when 'tape economy / conservation' was paramount, and generally was not acceptable for 'music quality' recording.

Early 'consumer' decks and most portables, including the small 3" / 'transistor / pocket' reel to reel decks utilized a 2-Track / 1-Channel format. This would include the earliest of decks 1950's thru early 1960's for 5" and 7" decks and the small 'transistor / pocket' decks from the 1960's thru the 1970's. The speeds on those could be anywhere from 1 7/8 ips thru 7.5 ips, depending on the unit / model.

Sony made quite a few decks that were 4-Track / 1-Channel (TC-105, TC-105A, TC-123, models come to mind). Sony also made a few that were 4-Track / 1-Channel or 2-Channel (TC-200). Akai / Roberts made decks with similar formats as well.

Some tapes can 'cross pollinate' to a 'usable' degree from one deck to another. For instance, you can play a 2-Track / 1-Channel tape on a 4-Track / 2-Channel deck. You will simply need to 'mute' one channel as you will get one side going forward and one going in 'reverse' (think 'backward masking' sound). Technically you'll get the 'forward' playback sound form the 'left channel' and Side-B (the other side) going 'backward'. Simply 'mute' with your 'monitor switch' or your 'Balance' control on your pre-amp or ultimately if necessary, pull out the patch cable on that side to only hear or transfer the 'forward playback' signal. Yes, you will be missing some of the 'audio signal strength' (as the head is not 'covering' the full width of the original recorded track), but given the material that was typically recorded on early 'mono' recordings, it's typically a fair trade-off to the resources that will likely be necessary to acquiring a 'functioning' deck capable of the exact track format.


...I'll add more to this as time allows


*A note about Reverse / Auto-Reverse /: Reverse means that you can manual switch directions in play mode. You can generally do this at any point in the tapes travel.
Auto-Reverse usually means that a deck will automatically switch play directions at the end. This is usually triggered by special foil tape installed on the tapes for sensors on the machine to pick-up. Some machines also require longer foil tape than others. Also decks vary in the side the foil tape has to be installed on to function. If you tape does not have the foil installed or it's foil is too short, or it happens to be installed on the wrong side, Auto-Reverse may not function. Auto-Reverse may only be designed to work in one direction as well. Some decks, such as a few 'Sony's' were designed with their "E.S.P. Auto Reverse", which would change directions after a 'long enough section of 'silence' ' passed by...theoretically...

Fixer-Upper, All-Tube, Sony TC-500a Reel to Reel tape deck / player / recorder.
Another one we are clearing out in 'as-found' condition. We just likely aren't going to have time to restore them all so it's for sale 'as-is'.
 
What we know / observed:
- Clean inside and good condition out
- Powers-Up fine
- Motor Runs
- Has very little (inadequate) torque on Fast Forward and Re-Wind function likely due to 'glazed rubber idler tires'
- Capstan turns, but play will sometimes slow down, again likely due to glazed or worn rubber. Could be Start / run caps, but until the rubber is reconditioned or replaced, you would be 'guessing' (of course it doesn't hurt to proactively replace the 'start / run' caps)
- Counter functions
- Tape made sound from both channels
- Very dirty Record switches
- Tape deck does record a signal on Right channel, but low on left. May need a new tube in that circuit.
- Functions vertically or horizontally (will need reel clamps for 'vertical' use which aren't included)
- All Lights / Bulbs for 'Recording Indicator' and 'Meters' work
- Pinch roller appears serviceable
- Internal idler tires / wheels, have cracks. May be restorable, but may also need to be rebuilt / replaced with reconditioned ones (they're available out there)
- Decent cosmetics (may be dusty / dirty etc.)
- Actually not too many electrolytic capacitors inside to change (we may have a 'change of heart' on this one and restore it before it sells because of that)
- We removed the AC cord jack cup, so it will need a replacement or better yet, just change to a 'fixed' AC mains cord
- Missing the 'Sony' logo from head cover, the 'bright' from the speed change knob, and the set screws from the plastic head cover
- All original NEC tubes
- Internal Tube Amp sounds decent from both L & R
- External Speakers both function well
- All I/O jacks works well

     *Ok, so here's the deal on our 'As-Is' / 'As-Found' / 'For Restoration' units. The prices are firm and are more based from their 'pre-processed parts value'.  We are offering these As-Is units simply because theyre below our threshold of time-vs-effort-ROI at the time of posting. Any less than our published price and we'll go ahead and process them as "parts" and remove from sale or re-slate for future restoration by us as time allows.  At these values / prices, no more photos or testing will be done by us.

     Most or all of the following applies to us as well, EVERYTIME we start the refurb / service process on a unit. While we may sometimes (usually) state what functions / condition we observed at the time of testing, it is in no way a declaration of warranty (meaning; we may have missed some $%#*).  The existing condition we observed and documented is also no guarantee of ultimate viability following further service efforts.  It is only offered 'As-Is', without our normal *warranty and we won't have the time resources to 'improve' it in anyway.  The existing condition we observed and documented is also not necessarily indicative of the entire cosmetic / operational condition associated with a unit (theres probably issues we didnt or couldnt see at the time).

     Restoring / refurbishing 'vintage / used' units properly is typically not an 'easy' process and if you are 'not' a technician or will be disappointed if a unit does not come all the way through to fruition, then you should probably purchase a unit that has already been restored to 'working' condition.  If you are not a technician and do not understand the potential dangers of working with electronic / electrical units, then DO NOT ATTEMPT repair / restoration / further service or even open a unit up. The voltages inside these unit can kill you and it will hurt the entire time you are dying!!!  Units should probably not be powered up or used until, at least, a cursory check by qualified personnel has been done.

     Parts to restore / refurbish / service or 'further improve' the unit may or may not be readily available (most parts can be sourced).  Parts / units may or may not respond positively to further repairs (you might blow something up). Units may or may not have original parts. They may have missing, damaged, modified, dangerous / outdated parts etc. (most will not). Units may have evidence of past non-factory, incorrect, uncompleted, shoddy or dangerous repairs (most will not).

     These units are NOT intended for someone looking for a 'working' unit or thinks you can simply 'install a new belt', spray in some contact cleaner or change a light bulb and have a working component.  It typically requires 4-18 hours to bring most units / vintage components back to a decent level of function and utility for the 'long haul'.

     The pack / ship will be the same as for our 'fully restored' components so the reduced price of the "As-Is" unit has NO BEARING on the cost to pack and ship (which is typically somewhere between $45-$85 but can vary up or down from that range). shipped to most of the lower 48 states. Extreme Southern, North Eastern, or North Western locales will be slightly more.

     Bottom line; If youre not up for the challenge either due to lacking skill sets or lacking funds to hire the work done, and need a unit to be more than a shelf display, then I would pursue a unit / component that has already been PROPERLY restored / refurbished / service with a clean bill of health. This goes for most of the units that are for sale on on-line Auctions and Classified ads. Occasionally there will be a unit up for auction or on a classified ad that really has been service properly, but theyre generally a single digit percentage of whats out there available for sale.

SOLD 8/19/20
SHIPPED TO PETER IN CALIFORNIA


 Our technician has completely gone through and 'Certified' this unit.

 We have completely gone through the mechanicals and electronics of this unit.

 All Power supply outputs tested and verified at spec.

 Transport mechanisms disassembled, cleaned, lubed w/ 'SuperLube', silicone based gel and light machine oil as necessary and reassembled including PR Pivot Arm mechanism.



 Tape Tension arms disassembled, cleaned and re-lubed, and had fresh 300,000 grade silicone lube gel applied

 Replaced both reel tables / spindles

 Tape Left Tension arm had extra spring tension added for better performance on tape handling

 Capstan flywheel removed, cleaned bushings and axels cleaned and re-lubed w/ 80-90W gear oil. Flywheel surface burnished.

Capstan Motor re-lubed (has 'oil tubes')

 Capstan cleaned and burnished in drill press while removed

 Pinch-roller mechanism completely disassembled, cleaned and re-lubed.

 Rubber pinch roller removed, re-surfaced, conditioned and re-installed with fresh lubricant.

 Impedance roller had both its end bearings removed and new ones (#626) pressed in for silent tape transportation.

'Main' / Capstan belt reconditioned.

 Fresh, new counter belt (#049) installed.

 Heads have been cleaned and de-magnetized as well as the entire transport.

 Brakes adjusted on fast wind modes also (optimized for 7" & 10.5" tape.)

 Back tension checked / adjusted on both reel motors.

 All three motors test perfectly. Following above adjustments, Reel Start and Stop tested at beginning, middle and end of 7" & 10.5" tapes (VERY QUICK 'FAST WIND' ON THIS ONE)

 Both spindles in perfect alignment w/ no 'run-out' at any speed.

 Both spindle-locks hold tightly.

 We also adjusted the reel table heights.

 Heads in great shape as well, with lots of performance left in them

 Removed and burnished COMMONLY INTERMITTENT contacts on channel Circuit Boards and re-seated. Adjusted pin contacts for better connections. Was discovered that these connectors was the source of channel intermittence.

 All meter lamps replaced #25-455

 Both 'Counter' lamps replaced #A403

 All 'internal' / PC mounted pots, switches and controls cleaned and tested for noise-free function

 All 'User' pots, switches and controls cleaned and tested for noise-free function


 Playback and Record Head alignment / azimuth was adjusted for peak performance with factory test tone tape and oscilloscope.

 We adjusted the VU meters mechanically for correct 'resting position' and electronically w/ factory test tone tapes, as well as the internal playback, Monitor levels, and record levels utilizing STL test / alignment tapes.

    


 We adjusted the Bias for great sound with Ampex GM-456 tape.

 Speed tested to 99.9% accuracy following refurb (meaning that our 'verified' 1000Hz accuracy using a 1000 Hz STL test tape.  (test tape now plays back at 999Hz when warmed up).


 
 Adjusted to record AMAZINGLY WELL at 0dB both with full bandwidth Pink-Noise, then 1kHz test and in 'Real World' use w/ 'mixed DDD CD' signals. (Tested with Maxell UDXL Tape and Ampex GM-456 (best results with Ampex GM-456).

 Floor noise measured at >-60dBm w/ blank tape, L&R

 Following refurb / service mechanicals tested for 'play torque' at beginning and end of largest size reels, as well as 'Fast wind torque' and 'braking tension' in both FF and REW, at beginning, middle and end of tapes. In other words, every combination of transport function was tested and passed.

 This TEAC / TASCAM 40-4 functions, plays, and records VERY WELL (and we really put them through the paces, testing both with well mixed, recently recorded CD material and CD recorded / factory test tones looking for correct head Azimuth and speed accuracy).  (Total time investment in refurb / testing ~ 24 hours).

 This deck had been rack-mounted so it arrive with NO side panels. We sourced a pair later (took about a year of looking / waiting)

This is an amazing deck for both recording or playback, again of Multi-Track / Four-Track / Four-Channel / Stereo /
**Quadraphonic / Mono' tapes for speeds of 7.5ips or 15ips. Following refurbishment, the deck looks and works great and sounds amazing!!! 

The encore to the TEAC / A-3440, the TEAC / TASCAM 40-4 Multi-Track / Four-Track / Four-Channel / Stereo / Quadraphonic / Mono (Yep, that pretty much covers everything but 'half-track') Reel to Reel tape deck. Ready to GO! We've had this deck in our warehouse for years, waiting for a 'senior tech' who was qualified to the task of bringing such a deck back to life CORRECTLY. One of a recent few, we've had make it through satisfactorily in 24+ years of dealing in vintage audio.

This is the deck that most folks want for their home studio to record 'raw tracks' on. For examples; you could lay down bass and drums on one track, then rhythm guitar on the next track, lead guitar on track 3 and vocals on track 4. Or you can lay down tracks 2-4, then bounce them to track 1 and have 2, 3 & 4 free again. Or you can records 'heads-up' (all four tracks at once), then mix those down later. Of course, you can record 'normal stereo' tapes, or you can record 4 separate mono tracks if you're trying to conserve tape. Or, Or, Or...

 Following our extensive refurb / bench time it's now an AMAZING performer (Check the 'recording test results' above and the 'specs' in text below). If you're looking for a reel to reel deck to "actually use" here you go. Only about 25% of the used Reel decks out there can be "practically" restored to working order. This one made it through with flying colors after about
24 hours of bench time.

From the original TEAC / TASCAM 40-4 brochure:
They are ideal for a wide spectrum of uses: tracks for a record album, making commercial spots, or doing production work in radio, TV or Film. You can make superior recordings with these easy to operate recorders, and you get the quality and reliability for which TEAC is known. (of course as it does all of those professional tasks, it can certainly do anything you need at home).

The deck tests great! Cosmetically it's in good condition. Cosmetic issues worth mentioning would be a veneer chip to the lower, left side panel, some scuffs / striations to the rear edges of the side panels, a note-worthy ding to the upper right side panel corner, a small 'dent' in the faceplate near the right tension arm. As we stated earlier, the deck had been rack-mounted so it arrived with NO side panels or rear sheet metal. Sometime in the past, an 'accessory' port was drilled in the rear panel, that is no longer utilized. Also, as it had been rack-mounted, there's no 'plastic' skids installed on the bottom (even though they're shown in one photo, those were from a previous deck), just 'felt feet'. We sourced all of it later from another deck we purchased. (see photos above). Functions and sounds great ! Will play up to 10.5" reels.

TEAC / TASCAM 40-4 Features include:

- Multi-Track / 4-Track / 4-Channel Stereo / Mono head stack / tape format
- DURABLE AC powered capstan motor (lasts decades longer than DC capstan motors of the 'later' models)

**(Can also play 'Quadraphonic' tapes as long as your tapes are 7.5 or 15 ips. Of course you can record 'Quadraphonic' tapes as well if you have the supporting resources)
- 3 Heads for instant monitoring of tape levels while recording
- 10.5" Max Reel Capacity (The BIG Reels!)
(*but could play down to 3", however the torque and brakes are optimized for 10.5" reels) (when in "fast wind" mode, it is sometimes necessary to switch to "Large Reels" when utilizing 7" or smaller reels to keep tension arm from moving to 'auto-shut-off' position)
- Punch In / Punch Out Function
- 3 Motors (means less 'Rube Goldberg' mechanisms inside like many R2R's)
- IC logic tape transport for "Touch" control
- Dual speeds at 15ips / 38cms & 7.5 ips / 19cms
- Multi-Track / Sound-on-Sound / Sound-with-Sound / Duet recording capable
- Cue Lever with 'variable pressure' for lifting tape away from head in Fast Wind modes or for moving tape close enough to head to monitor fast wind progress
- Output selector for Input, Norm or Monitor (this feature will require an understanding of the 'user manual')
- Play / Pause control lets you manually rock the reels back / forth while you listen to pinpoint an exact point for editing. (also if youre the DJ type, you can also use this feature to scratch-n-sniff just like on your records. Can you say, Yipeeee! ?... Oh sorry, I mean, Yo Dog)
- Reel Size selector for proper tape 'back tension' and braking.
- Variable Input level control for each channel
- Analog VU level meter for each channel
- Analog Tape Counter
- Spring loaded reel spindles (no need for 'rubber stoppers / reel clamps')
- RCA Line I/O's for all channels
- Accessory connectors for optional TEAC Remote control (not included, nor currently available)
- Multi-pin logic connector for external dbx unit (not included, nor currently available)

As stated earlier we have EXTENSIVELY gone through it cleaning heads and all else, lubing, adjusting, reconditioning pinch rollers and other rubber parts, demagnetizing heads and entire transport and testing everything. Tape speed tested and resulted in 99.9% accuracy using a 1000 Hz STL test tape. Plays and records Exceptionally well (and we really put them through the paces, testing both with well mixed CD material and CD test tones looking for correct head Azimuth, tape speed accuracy and making test recordings. Again, check the 'test results' listed above). Pinch rollers and heads all in GREAT condition!!! As stated earlier, cosmetic issues worth mentioning would be some light scuffs on the face panel, between the reel tables and a few, typical nicks to the wood grain side panes, and a small nick to the head cover (see photos above).

This is a highly sought after deck and now, following the extensive service, with UNBELIEVABLE PERFORMANCE.
This was not only a GREAT 'Musicians' deck, as a performer could 're-visit' their old band tapes to transfer to computer, DAW, or 'Stereo Mix Down', but since it also does standard 'Stereo' playback, Mono and even Quadraphonic (Quadriphonic) playback, it's about as versatile as you can get. Also would be a great deck for a 'media transfer house / business' that has clients with old 'band tapes' that they want to get mixed down to stereo.
All of our restored / refurbished reel to reel decks come with a 7", plastic take-up reel, a 'known good' 7" tape for initial testing of playback, and a 7" tape you can record onto, all to assist you in becoming familiar with the operation / function of your new reel to reel tape deck.
Comes with an 'e-copy' / pdf download of the TEAC / TASCAM 40-4 owners / operations manual. Measures 21" tall (with skids installed) x 17.3" wide (w/ wood side panels installed) x 21.5" tall x 12" (from tip of back feet-tip of hubs) deep and weighs a
VERY HEAVY 72+ lbs unpacked. Includes our standard 90 day limited warranty.
(Reels, tape and any NAB hubs shown in photos not included. All are sometimes available separately if you need them. We do ship our decks with a plastic take-up reel, a tape to 'practice record' on and a 'pre-recorded' tape for playback.)

SHIPPED TO BOB IN COLORADO


 Our technician has completely gone through and 'Certified' this unit.

 We have completely and extensively gone through the mechanicals and electronics of this unit.

 Entire transport was disassembled down to the chassis, and every mechanical part was cleaned, de-greased, and re-lubed including; Pinch Roller Pivot Arm, EOT Sensor Arm, Left Tape Tension arm mechanism, Capstan Motor (disassembled, cleaned and re-lubed w/ 30wt), Capstan and flywheel shaft removed cleaned / re-lubed w/30wt (pretty much every moving part)

 Transport cams checked for usable condition prior to any work starting (here in the West, we have less of an issue with the typical deterioration that you see in more 'humid' climates such as the Mid-West, South and Coasts (be very careful getting an Akai from the early to mid 1970's that has spent most of it's life in a 'humid' environment).

 Entire 8-Track transport assembly was removed and disassembled for service, including burnishing it's connector, and track selector contacts.



 Motor completely disassembled, cleaned, & re-lubed

 Voltage re-set to correct 120VAC

 Circuit board edge card contacts and connectors burnished w/ solvent and fiberglass pen



 Tape Tension arms disassembled, cleaned and re-lubed, and their springs adjusted

 Reel table height correct

 pinch-roller 'arm' mechanism completely disassembled, cleaned and re-lubed

 Capstan / flywheel removed, bushings and axles cleaned and re-lubed and flywheels burnished

 Capstan motor pulley burnished

 Capstan cleaned (as well as the internal and external surfaces of the original speed sleeve)

 ALL Internal idler tires cleaned / reconditioned

 Rubber pinch roller removed and re-conditioned

 New MAIN drive belt, #FR13.4 installed

 Brand new counter belt, #047 installed

 Repaired faulty motor 'Speed Switch' that was causing motor run intermittency

 Repaired damaged internal wire insulation from previous service

 Repaired Tape EQ switch

 Repaired Cart / Reel selector switches

(Note; these units have numerous internal switches other than what seems to be the obvious / visible ones upon initial disassembly. Most switches have ADDITIONAL switches located further inside unit, connected with linkages that also must be serviced. We've done a few of these now, and you learn.)

 Replaced 'Track Change' relay, 1000uf electrolytic capacitors on 8-track transport board for quieter track changes

 Heads have been cleaned and de-magnetized as well as the entire transport (reel and 8-Track Cartridge).

 Brakes adjusted on fast wind modes at ALL points thru a tape. It's a fine line between having the brakes actuate with too much tension, 'abruptly' stopping the tape (risking stretching / breaking of tape) or too loose (allows tape to 'dump'). (VERY difficult to do on this series). Brakes optimized for 7" reels.

 Motor torque test perfectly. Following above adjustments, Reel Start and Stop tested at beginning, middle and end of 7" reels.

 Internal pots, switches (including linear record switch and 'rotary wafer' switches) and controls cleaned and tested for noise-free function (initially, of course, had typical static / noise which is to be expected in an 'un-serviced' deck after 45+ years) (also a bit easier on this "Type-C" version. Just FYI).

 External / User adjustable pots, switches and controls cleaned on the playback / record amp and tested for noise-free function

(tech notes; Line out set to 0dB using 0dB reference @ 700Hz. Vol controls @ approx 1:30)

 Replaced VU meter lamps / bulbs #25-080

 Cleaned 8-Track cartridge heads

 We adjusted the VU meters mechanically and electronically w/ factory test tone tapes, as well as the internal playback levels for both directions independently and record levels.

 We adjusted the output, 'Minimum Input', 'Specified Input', 'Record Level' and 'Bias' all to spec, then further adjusted 'Bias' for Ampex GM-456

 Both spindles in perfect alignment.

 Heads in great shape as well, with many years of performance left in them

 Playback and Record Head alignment / azimuth was adjusted for peak performance with factory test tone tape and oscilloscope.

 Speed tested to 99.3% accuracy following refurb (meaning that our 'verified' 1000Hz test tape now plays back at 1007Hz +/- 2Hz. {well within spec by 7Hz!}).
 
 Reel Tape deck adjusted to record VERY WELL. Biased for Ampex GM 456 studio tape @ 0dB!!!

 'Real World, DDD CD recorded sounds great w/ Ampex GM456.

 'Electronic' Floor noise measured at >-60dB w/ blank tape, L&R.

 Motor had a slight amount of run-out detected at the belt pulley (side to side movement / play) which causes excessive, ambient noise, so we swapped it with another of the exact motor (we had a 'donor unit'), which was then also, completely disassembled, cleaned and lubed w/ 30W.

(tech notes; internal amp tests well w/ ~ 1mVDC across outputs w/ 8 Ohm load. Also as a side note, the Akai X-1800SD C-Type utilizes the same output transistors as the later Akai X-1810.)

 This AKAI X-1800SD functions, plays, and R2R portion records VERY WELL (and we really put them through the paces, testing both with well mixed, recently recorded CD material and CD recorded / factory test tones looking for correct head Azimuth and speed accuracy). Unfortunately, while the "8-Track" tape deck plays VERY WELL, we were not able to get it to record, and didn't want to 'chase' it indefinitely thus raising the final price disproportionally (Total time investment in refurb process / and final testing ~ 32 hours).

The AKAI X-1800SD Stereo Reel to Reel tape deck. Ready to GO! This is one of the few reel to reel decks we get in that make it to our finished page. Great performer. If you're looking for a reel to reel deck to "actually use" here you go. Only about 25% of the used Reel decks out there can be "practically" restored to working order. This one made it through with flying colors after about 21 hours of bench time.

Following mechanical / electronic refurb, entire unit was cosmetically detailed inside and out. Face is made of aluminum and is dent free and in great condition. Cabinet covered in real TEAK wood veneer, is in decent condition with just a few 'battle scars', mostly to the 'top' side of the wood case (see photos above) and just had a fresh coat of Howards 'Restore a Finish' and followed Howards 'Feed-n-Wax'. All the case hardware intact and working, and had all it's fasteners torqued down. Deck looks and sounds great! 
   ____________________________
   
Looks great & "Ready-to-go"  AKAI X-1800SD Stereo Reel to Reel tape deck. Very 'famous' and popular reel tape deck. Many of the folks stationed overseas in the military during Viet Nam that purchased a Reel to Reel came back with an 1800SD (or one of it's siblings). Unfortunately of course, 50 years has not been kind to Akai Reel decks (or any electro-mechanical devices that are 20 years old or older). The internal lubes were never meant to last that long, certainly without maintenance, and 'rubber' doesn't 'age well' either, thus requiring the above stated work. There's also the Akai Transport cams that need to be inspected for their degree of condition and replaced if necessary (difficult and potentially expensive). We've already inspected them for any detrimental issues and certified them ready to go. Will play & Record stereo 1/4" tapes on reels up to 7". This is one of the few reel to reel decks we get in that make it to our finished page. If you're looking for a reel to reel deck to "actually use" then here you go. Only about 25% of the used Reel decks out there can be "practically" restored to working order. This one made it through. Playback & transport functions test great and records well! 8-Track, built-in amp and speakers all work great as well. Looks and sounds great too!
Another note I'd like to make is that the 8-Track is probably the BEST I've ever auditioned (and we've done A LOT of 8-Track decks, and I used to sell them when NEW).

AKAI X-1800SD Features include:


- 4-Speed
* Reel to Reel, 8-Track Cartridge deck w/ built-in speakers and amp
- DURABLE AC powered capstan motor (While "AC" Capstan motors generally have a bit more 'mechanical noise' that is typically noticeable in quieter environments, they are known for lasting decades longer than the DC capstan motors of the 'later' models)
- Up to 7" reel capacity (while you could go down as far as 3" in diameter, the torque and braking on this deck has been optimized for 7"reels)
- Akai's "Cross-Field" Bias Head, gets the tape 'bias signal' off of the 'Record' head (so the 'Record Head' can be concentrated only on recording the 'music' signal) and biases with a separate head
- One-Micron Gap Recording Head (reel)
- Stereo or MONO playback / recording (reel tape) (means that in "MONO" mode, you can record 4 separate passes on a tape or playback tapes made on older decks that did 'four separate tracks')
- Quad speeds at 7.5 ips / 19cms (with included speed sleeve adapter), 3 3/4ips / 9.5 cms,1 7/8 ips / 4.8 cms &
*15 ips / 38cms (requires optional 15ips kit, not available from us.
- As it's got its own, Built-in Power amp and speakers, it can be used as a 'stand alone' unit. (very handy for a media transfer business setting up another 'station' without a stereo / audio system)
- Stereo playback / recording 8-Track Cartridge tape
- Continuous Play or 'End of Tape' Stop for 8-Track (however at this point the 'Auto-Stop' does not seem to recognize the 'sensor' tape on 8-tracks so only does "Continuous Play" at the end of track #4)
- 8-Track 'Track Selector' w/ typical indicator lights
- Auto-Off for Reel deck
- Can also transfer from Reel tape to 8-Track Cartridge tape
*
- Built-in 'Tape Cleaner' pad (can also lube 'back coated' tapes so they don't squeak if you can obtain the correct silicone lube. No, we don't know where to get it at this point...yet)
- Dual front mounted 1/4" Microphone inputs
- Side mounted 1/4" Headphone jack
- RCA and DIN I/O's
- Separate L&R Input / Volume controls
- Separate L&R Tone controls (for built-in amp)
- Internal Speaker On/Off switch (Auto switches when using 'External' speakers)

- NOT an OFFICIAL feature, BUT one function this deck will allow is a sort of CUE by slightly pushing up on the 'pause' lever, while the deck is in play, you can get a 'variable speed' CUE function. You'll either need to very gradually release the pressure or with your other hand move the 'Play' lever to 'Stop' when you reach the spot you wanted to 'cue to' or the tape will track off the front edge of the pinch roller. Takes a bit of practice to get it right.

(
*15 ips ONLY w/ optional speed sleeve / pinch roller kit (not typically avail. The 15ips was utilized for transferring Reel tape signals to the 8-Track tape. While the Reel deck could record at 15ips, there's not a 15ips Tape EQ setting, which may or may not be detrimental to your needs)
-True "WORLD AC POWER" allows unit to be operated on 50 or 60 Hz AC and will select voltages from 110v, 120v, 220v and 240 volts AC input.

This is only the second AKAI X-1800SD we restored in ~24 years. Great machine for playback / archiving your tapes to CD or Hard Drive or for recording new tapes. This is a beautiful deck. Performs incredibly well following extensive refurbishing. The wood case is in great 'structural' condition. It exhibits the typical and expected finish fading / checking / dings. The decks face, knobs, covers and all cosmetics are fabulous!

This machines 'Forte' would be best suited for a 'media transfer' business, especially where you have a bench / station that doesn't have dedicated sound system (as it's go it's own, built-in amp and speakers) or for someone who has a lot of tapes to preview prior to sending for transfer, or for a library or university with a lot of tapes of different speeds / and track formats to transfer. If you're going to be listening to 'quiet, chamber' music while reading, the "AC powered" motor / fan noise could be noticable while 'casually' listening to quiet passages of music. If you tend to like the volume at more than 'low, back ground' levels, then you'll not likely notice "AC powered motor" hum. There is a bit of "60 cycle" hum on the outputs (typical again, of earlier, AC motored decks) that will be noticeable if you have the decks outputs above about "3:00 O'clock" / 75% of the way up, your pre-amp is above 11:00 O'clock (almost 'half way') up and the deck is in 'Pause' or playing a very quiet passage of music. Probably won't be noticed in most playing situations. If you're utilizing if for 'media transfers', you can simply turn on a 60 Hz filter in the software to remove / reduce it. If you have a graphic EQ, you can do the same, again, if you have the deck and your volume both turned very high.

Measures 13.5" wide x 15" tall x 9.5" deep and weighs 38 lbs unpacked. Includes a set of 'fresh' spindle stoppers / reel clamps. Comes with a pdf 'e' copy of Akai X-1800SD owners manual and original brochure. Can include the AKAI X-1800SD Service Manual pdf 'e' download if you wish as well. Includes our standard 90 day limited warranty.

SHIPPED TO BARRY IN MARYLAND


 Our technician has completely gone through and 'Certified' this unit.

 Importantly ENTIRE internal transport COMPLETELY disassembled, cleaned of old grease & re-lubed.

 Both Main Drive belt and Counter belt have been reconditioned for trouble-free service.

 Rubber pinch roller has been reconditioned, as well as all internal drive tires / wheels for positive grip.

 We also burnished the capstan

 heads have been cleaned and de-magnetized as well as the entire transport.

 Always at issue on these machines is the Pinch Roller swing arm assembly that has been completely disassembled, cleaned and re-lubed.

 Also hub brakes have been cleaned, re-lubed, and adjusted on fast wind modes also.

 Following above adjustments, Reel Start and Stop tested at beginning, middle and end of 'loaded' 7" tapes.

 Motor has been re-lubed as well.

 All internal pots and controls cleaned and tested for noise-free function.

 Both spindles in perfect alignment.

 Following initial refurb, we found tracks 1-4 to be diminished in high frequency response relative to tracks 2-3. We decided it could only be attributed to excessive wear to the Play / Rec head. After inspecting a number of replacement heads, we found one from a TC-200 (same head part number, and is the same head used in most of the Sony decks from that period) and installed it. Following that, we were able to bring the top end of 1-4 to within about 4dB of 2-3

 Head alignment / azimuth has been checked for peak performance.

 "Playback is now strong (following 'head-ectomy' with good 'top end' response.

 Heads now in good shape as well, with plenty of performance left in them.

 Plays perfectly on all tracks.

 Speed checked to 99.4% accuracy  (meaning that our 'verified' 1000Hz test tape now plays back at 994Hz).

(Total time investment in refurb / testing ~ 24 hours {yes, WAY TOO many hours on about any deck, but that's how it goes sometimes}). This unit was very clean and well cared for when we started on it.

Cosmetically in very clean condition! 
 
 ____________________________

Very simple Sony Reel to Reel Play / Record tape deck. Nothing fancy. While it will play both channels of a stereo tape, the signal out is blended. The deck can be a "stand alone" unit  as it has a built in amplifier and speaker, or can be connected to a CD burner / sound system. It is designed to be used horizontally. Great "industrial / school / institutional series deck. Perfect for those early / old reel tapes that were recorded in mono or the tapes recorded utilizing all 4 separate tracks to conserve tape.
New Info / Notes: While the manual doesn't mention it, we have played 'mono / 2 sided' tapes back on these machines. As the deck only plays 'half' of the sides material at once, your S/N ratio would not be as good (meaning you might have a bit of extra 'hiss' with the sound), but we tested with some old recordings and were not able to hear much of a difference / issue (while playing 'mono / half track' tapes, you monitor the 'forward' playing track by manipulating the 'Exchange' switch. You will either hear the 'intended' track playing forward, or the other side playing backward. Simply turn the tape over to hear the 'B' side going the correct direction.
As far as playing 'stereo' or more modern (post about '67 or so) tapes, that were recorded on a 4-track / 2-channel deck, playback results will depend on how the tape was recorded. If it was recorded in 'stereo' with a 'hard left and right' pan, you may only get part of the recording at a time; ie; mostly vocals by themselves or mostly instruments by themselves, as in the case of some Beatles recordings or some Canned Heat recordings. If the music was recorded panned more to the center or more 'mono', then it will likely be sufficient.


Sony TC-105 Features include:

- Triple tape speeds at 7.5 ips / 19cms, 3 3/4ips / 9.5 cms and 1 7/8 ips / 4.8 cms
- DURABLE AC powered capstan motor (lasts decades longer than DC capstan motors of the 'later' models)

   - Mono Playback & recording

 Our technician has completely gone through and 'Certified' this unit.

Original tech notes on 'pre-inspection';
"Dirty, but relatively unmarked...take-up bushing loose in chassis...AC power cord frayed....Voltage incorrectly set to 110V...Playback head VERY worn...main drive tire dried & cracked and will need to be replaced...dents in pinch roller...FF & REW partially function. Entire transport needs total overhaul...motor is quiet...main drive belt stretched / cracked...Right channel very low output...speed; unable to determine as entire transport doesn't function well enough...VERY noisy controls...leaf switches intermittent to non-functional...Rec pressure pad too flat...very little high frequency likely due to excessive head wear."

 We have completely and extensively gone through the mechanicals and electronics of this unit.

 Entire transport was disassembled down to the chassis, and mechanical parts cleaned, re-lubed and reassembled.

 Flywheels removed, cleaned and reinstalled.

 Capstans burnished

 Again, the entire transport assembly was painstakingly disassembled, cleaned and re-lubed.

 'Auto-Stop' mechanism disassembled and re-lubed with fresh 300,000 silicon damping fluid.

 Also hub brakes have been cleaned, re-lubed, and adjusted on fast wind modes also.

 Main AC / Line / Power switch replaced with Original Sony from a donor unit

 Burnished leaf switches

 VU meter illumination lamps / bulbs check fine.

 Both spindles were completely disassembled, cleaned and had their bearings / bushings cleaned and re-lubed and are in perfect alignment and run 'true' (see above photos).

 Heights adjusted on both reel tables.

 Replaced dried / cracked idler tire with 'reconditioned' unit

 Main Drive and counter belts replaced for trouble-free service.

 Rubber pinch roller removed, cleaned & reconditioned, as well as all internal drive tires / wheels for positive grip.

 Combination Record / Playback head replaced with sourced OEM unit in good shape

 Tape heads and entire transport cleaned and demagnetized.

 Heads in great shape as well, and should have many hundreds of hours of performance left in them.

 All Amplifier controls and input selectors cleaned extensively

 AUX, Tuner and Phono inputs all tested fine on both channels following 'control cleaning'

 Amplifier tested on both channels (not a 'power house' of volume, but fine for 'lower volume' needs. Will get as loud as you need it to once connected to your system).

 Both speakers tested and frequency swept with no issues (internal and external, but again, won't get 'room filling' loud as they're simply to monitor playback).

 Speaker wires, amp input jacks and plugs all in perfect condition

 Head alignment / azimuth has been checked for peak performance on both play and record heads with factory STL 1k, 5k, 7.5k, 10k & 15k tones with oscilloscope.

 Records well, but much lower on VU than input (about -12-15 dB). Sonically fine. Biased for *Ampex GM 456 studio tape with the following results:
1kHz recorded @ 0dB resulted in PB @ -15dB (with minimal 'artifacts')

'Real World', DDD CD recorded at 0 = -12dB but sounded fine. This deck is a much better 'playback' unit than a 'record' unit.

* We also had great results with Maxell UD XL (Gold Box) tape as well
Note: If you're going to be making 'new' recordings, you'll want to 'push' the levels well into the "red" to get a good PB level.


 Floor noise measured at -60dBm w/ blank tape, L&R

 Both PB output levels and VU meters playback internally adjusted for even response.




We really put them through the paces, testing both with well mixed, recently recorded CD material and CD recorded / factory test tones looking for correct head Azimuth and speed accuracy).

Tape Speed tested to 100% accuracy on each speed independently, via cir bd micro-pots, utilizing 'factory' test tapes meaning that 1000 Hz tape plays back at 1000Hz +/-1Hz!

 External Cabinet and some of the speaker hardware replaced with Original Sony from a donor unit

Following electro/mechanical restoration, unit received a cosmetic cleaning / detailing.

(Total time investment in refurb / testing 29 hours).
Deck is now in overall, GREAT condition!!!
   ____________________________


 
Great condition & "Ready-to-go", Solid State, Sony TC-530 R2R with built in amp and speakers. Built-in amp and speakers make this a "stand alone" unit, yet can still be connected to your stereo system.  This is one of the few reel to reel decks we get in that make it to our finished page. Great performer. If you're looking for a reel to reel deck to "actually use" here you go. Only about 25 % of the used Reel decks out there can be "practically" restored to working order. This one made it through to test great! Looks and sounds great! We have completely gone through it. Will play 3", 5"and 7" reels.

Sony TC-530 Features include:
 

- Triple tape speeds at 7.5 ips / 19cms, 3 3/4ips / 9.5 cms and 1 7/8 ips / 4.8 cms
- Independent L & R recording switches. Allows twice the record time when mono sound is adequate.

- DURABLE AC powered capstan motor (lasts decades longer than DC capstan motors of the 'later' models)

- Independent L or R playback switches. Great for playing those early "single track" tapes recorded in mono (this function works when using the built-in amplifier and does not affect the stereo Line-Outputs
- Built-in stereo amp and dual speakers featuring 3" x 6", Sony built, full-range drivers as well as 4" full range drivers built into case front speaker cabinets that form the front cover. (again, really good for simply 'monitoring' what's on the tape)
- Speakers detach to form the front of the case
- Built-in 8' speaker cables with storage in speakers
- Dual front mounted " Microphone inputs
- Analog Tape Counter
- Lockable Pause control
- Variable Volume control for internal amplifier
- Separate Bass and Treble controls for built-in amplifier
- Balance control for internal amplifier
- Separate Left and Right Record level controls
- Dual Back-lit, analog VU level meters
 - 1/4" headphone jacks
- Top-mounted patch-bay loaded with I/O jacks including; Outputs are dual RCA line In / Outs, 1/4" speaker outputs
- Dual AC convenience outlets
- External AC fuse protection
-True "
WORLD AC POWER" allows unit to be operated on 50 or 60 Hz AC and will select voltages from 110v, 120v, 220v and 240 volts AC input.
 

 As stated earlier we have completely gone through it cleaning, re-lubing, adjusting, demagnetizing and testing everything. All rubber parts inspected, replaced and / or reconditioned. Records at approx -12-15dB and Plays well (and we really put them through the paces, testing both with well mixed CD material and CD test tones looking for correct head Azimuth and speed accuracy
(speed is correct to 100% @ 1kHz) and making test recordings. All fast wind and stop functions work perfectly at any point in the tape. Only two minor cosmetic issues; AC cord storage compartment door missing and head cover securing screws missing. Head cover still stays on well with friction. Pinch roller reconditioned and heads all in GREAT condition!!! Face and knobs all in great cosmetic condition as is the original case, hinges and latches. Both speakers detach from the top and form the top of the case when latched. Speaker cables store in lids. Since this unit has a built-in amplifier, pre-amp controls, multiple inputs and built-in speakers, it can be used as a true "stand-alone" unit. The internal amplifier and built-in speakers actually sound great as well! Very surprising. Of course unit will still patch into any stereo / sound system normally. Measures 15" tall x 20" wide x  x 10" deep (with speaker / covers installed) and weighs 40 lbs unpacked. Includes our standard 90 day limited warranty. Also includes a pair of rubber hub stoppers! (Reels & tape shown in photos not included. All are usually available separately if you need them)

  Our technician has completely gone through and 'Certified' this unit.   We have completely and extensively gone through the mechanicals and electronics of this unit.

  Entire transport was disassembled down to the chassis, and every mechanical part was cleaned, re-lubed and reassembled.

  Pinch-roller Lift Mechanism completely disassembled, cleaned and re-lubed (requires pulling head block, and Meter CB, once entire front face panel is removed and is fairly time consuming, but must be done on about 50% of 909's)

  PR mechanism solenoid mounts adjusted

  Capstans / flywheels removed, bushings and axels cleaned and re-lubed

  Capstans burnished

  Rubber pinch rollers have been replaced with FRESH units

  Brand new drive belt installed

  Heads have been cleaned and de-magnetized as well as the entire transport.

  Power supply CB adjusted to correct 15.1VDC which enables best performance from Cap motor, Playback and Record amp circuits

  Both L&R Tape Tension arm mechanisms removed, completely disassembled and re-lubed with 500,000 grade silicone gel (time consuming process and must be done to about 75+% of 909's)

  Back tension adjusted on both reel motors.

  All three motors test perfectly. Following above adjustments, Reel Start and Stop tested at beginning, middle and end of 7" and 10.5" tapes

  Brakes adjusted on fast wind modes on both 7.5 and fully loaded 10.5 reels from top speed.

  Internal pots, switches and controls cleaned and tested for noise-free function.

  We adjusted the 'Blue Fluorescent' VU meters electronically w/ factory test tone tapes, as well as the internal playback levels for both directions independently and record levels.

  Deck has been fully calibrated to factory manual specs, tested, and found to perform like new in all categories.

  Both spindles in perfect alignment.

  We also adjusted the reel table heights.

  Heads have virtually no appreciable, visible wear. (heads also HAVE NONE of the common 'green, surface corrosion' that a lot of Pioneer tape decks seem to get {we've had loads with the corrosion, and haven't really found a good way to remove it when a deck has it short of 'lapping' them...which we don't do})    

  BOTH direction Playback and Record Head alignment / azimuth was adjusted for peak performance with factory test tone tape and oscilloscope.

  Both internal speed pots adjusted to 100% accuracy on 3.75ips and 7.5ips speeds  independently (with pitch control zero'd) (meaning that our 'verified' 1000Hz test tape now plays back at 1000Hz +/- 1Hz w/ pitch control at 12:00 position).

  Recording tests performed with Ampex GM456 tape. Heres how it tested with the following frequencies recorded at 0dB;
500Hz = +2dB, 1kHz= +2dB, 2.5kHz= +1dB, 5kHz= +1dB, 7.5kHz= 0dB, 10kHz= 0dB, 12.5kHz= 0dB, 15kHz= -1dB, 17.5kHz= -1dB, 20kHz= -1.5dB, 22.5kHz= -4dB, and 25kHz= -5.5dB. Pretty damn good numbers for a 40 year old classic!


  Floor noise measured at >-60dBm

  This Pioneer RT-909 functions, plays, and records perfectly (and we really put them through the paces, testing both with well mixed, recently recorded CD material and CD recorded / factory test tones looking for correct head Azimuth and speed accuracy).  (Total time investment in refurb / testing ~ 12+ hours).

  Face is made of beautiful brushed aluminum and is in great condition and has never been rack mounted. Deck looks and works great! 
____________________________
Looks GREAT & is "Ready-to-go"! The very sought after Pioneer RT-909 Stereo Reel to Reel tape deck. Will play / record stereo 1/4" tapes on reels 5, 7 & 10.5". This is one of the few reel to reel decks we get in that make it to our finished page. Great performer. This one made it through and all functions test great! If you're looking for a reel to reel deck to "actually use" here you go. Only about 25% of the used Reel decks out there can be "practically" restored to working order. Heads have no appreciable, visible wear, check the record test results above, evidence theyre sounding great! Recordings sound FANTASTIC on this unit now. Looks essentially NEW and sounds great too! This one has never been 'rack mounted' so no 'rack-rash' on the mounting ears. As touched on above, the heads are in beautiful condition, also with none of the common 'green corrosion'. The head cover and the reel tables are also free of the 'green corrosion' that is often seen growing on Pioneer RT's. Also, both the original plastic skids are intact and un-broken (afflicts about half the 901's and 909's out there (should typically be removed prior to shipping along with the reel spindles).
Again, we have completely gone through it. It has been in my personal office system here at OakTreeVintage for a few years, but I'm switching to a 'high speed' unit.

Overall, the sheet metal case is
in excellent condition.

These are great machines. I have had this one myself for years. It's a blast to put on a BIG 10.5" reel with Pink Floyds, "Dark Side of the Moon". Even though it was designed for the consumer market, many were and are in use in schools, universities, libraries, clubs, etc. I worked at a Sheraton Inn in the late 70's and early 80's, and we had two in the DJ booth, that supplied foreground music from about 11AM till the DJ showed up at about 9PM, 7 days a week!
Comes with an original (not it's) Pioneer RT-909 box and packing.
Also includes a pair of original, Pioneer PP-220 NAB Hub adaptors.

 

Also includes a 'non-Pioneer', Metal (Scotch brand with some surface wear), 10.5" take-up reel, as well as our normal accessory kit that includes a 'PlayBack Demo' made on the deck, a 7" plastic take-up reel, and a couple of other assorted 7" tapes to play with.

SHIPPING TO DON IN TEXAS


 Our technician has completely gone through and 'Certified' this unit.

 
We have completely and extensively gone through the mechanicals and electronics of this unit.

 Entire transport was cleaned, de-greased, and re-lubed including; Pinch Roller Pivot Arm, EOT Sensor Arm, Left Tape Tension arm mechanism, Capstan Motor (clean and re-lube), Capstan and flywheel shaft removed cleaned / re-lubed (pretty much every moving part)

 Transport cams checked for usable condition prior to any work starting (here in the West, we have less of an issue with the typical deterioration that you see in more 'humid' climates such as the Mid-West, South and Coasts (be very careful getting an Akai from the early to mid 1970's that has spent most of it's life in a 'humid' environment).

 Entire 8-Track transport assembly was removed and disassembled for service, including burnishing it's connector, and track elevator / selector contacts.



 Voltage re-set to correct 120VAC

 Circuit board edge card PCB contacts and connectors cleaned w/ solvent and burnished w/ fiberglass pen



 Replaced 'commonly black-legged', Hitachi C458 transistor as well as 'proactively' the other 3 transistors on Auto-Reverse control PCB

 Tape Tension arms cleaned and re-lubed, and their springs adjusted

 Bent Right reel spindle straightened

 Reel table height correct

 pinch-roller 'arm' mechanism completely disassembled, cleaned and re-lubed

 Capstan / flywheel removed, bushings and axles cleaned and re-lubed and flywheel burnished

 Capstan motor pulley burnished

 Capstan cleaned

 Rubber pinch roller removed and re-conditioned

 New MAIN drive belt, #42-550 installed

 Brand new counter belt, #042 installed

 Heads have been cleaned and de-magnetized as well as the entire transport (reel and 8-Track Cartridge).

 Brakes adjusted on fast wind modes at ALL points thru a tape. It's a fine line between having the brakes actuate with too much tension, 'abruptly' stopping the tape (risking stretching / breaking of tape) or too loose (allows tape to 'dump'). (VERY difficult to do on this series). Brakes optimized for 7" reels.

 Motor torque test perfectly. Following above adjustments, Reel Start and Stop tested at beginning, middle and end of 7" reels.

 Internal pots, switches (including linear record switch and 'rotary wafer' switches) and controls cleaned and tested for noise-free function (initially, of course, had typical static / noise which is to be expected in an 'un-serviced' deck after 45+ years) (also a bit easier on this "1810 than the "A-Type and B-Type X-1800SD" version. Just FYI).

 External / User adjustable pots, switches and controls cleaned on the playback / record amp and tested for noise-free function (tech notes; Line out set to 0dB using 0dB reference @ 400Hz. Vol controls @ approx 1:30)

 Replaced VU meter lamps / bulbs #25-080

 We adjusted the VU meters mechanically and electronically w/ factory test tone tapes, as well as the internal playback levels for both directions independently and record levels.

 We adjusted the output, 'Minimum Input', 'Specified Input', 'Record Level' and deck records well on Ampex 456.

 Both spindles in good alignment.

 Repaired broken internal connection lead wire for cap motor

 Heads in great shape as well, with many years of performance left in them

 Alignment / azimuth was adjusted for peak performance on Playback and Record Heads on both the R2R and the 8-Track with factory test tone tape and oscilloscope.

 "X-Field / Bias" head had it's clearance checked / adjusted w / feeler gauges.

 Repaired both 'Manual' Auto-Reverse switches

 Following initial restoration tests, we found we would have a channel drop out after playing for a while or when changing directions, and traced it to contact issues in the relays, thus the following operation...

 Both Play and Record relays (RL0201 & RL0202) had their contacts burnished on the 'Direction Change' PCB (not an easy task. Then tested 4 Hours with multiple manual reverses)

 Speed tested to 99.3% accuracy following refurb (meaning that our 'verified' 1000Hz test tape now plays back at 1007Hz +/- 2Hz. (within spec).
 
 Adjusted to record sonically well* with the following results w/ Input at ~ 9:00 when recording, then Output control re-set to ~"2:00 PM" for playback.

 'Real World, DDD CD recorded sounds great w/ more *quality tapes such as Maxell UD-35, TDK Audua, or Ampex GM456 rather than say Scotch 150 or Sony 150 etc.


 'Electronic' Floor noise measured at >-60dB w/ blank tape, L&R.

 Depending on the impedance of any headphones utilized with the unit, the volume can be lower they would be expected thru the headphone output.

 Motor was disassembled, had front and rear bushings cleaned and re-lubed w/ 30W. VERY quiet now.

 This AKAI X-1810 now functions, plays, and records WELL (and we really put them through the paces, testing both with well mixed, recently recorded CD material and CD recorded / factory test tones looking for correct head Azimuth and speed accuracy).  (Total time investment in refurb process / and final testing ~ 44 hours...DOUBLE OUCH!!!).

The AKAI X-1810 Stereo Reel to Reel tape deck. Ready to GO! This is one of the few reel to reel decks we get in that make it to our finished page. Great performer. If you're looking for a reel to reel deck to "actually use" here you go. Only about 25% of the used Reel decks out there can be "practically" restored to working order. This one made it through with flying colors after about 44 hours of bench time.

Following mechanical / electronic refurb, entire unit was cosmetically detailed inside and out. Face is made of flat-black finished, aluminum and is dent free and in great condition. Only minor cosmetic issues to mention, all to do with finish / Formica chips to the case edge (see photos above). Deck looks and sounds great!

Probably half the folks stationed overseas in the military during Viet Nam that purchased a Reel to Reel came back with an 1800 series. Unfortunately of course, 45 years has not been kind to Akai Reel decks (or any electro-mechanical devices that are 20 years old or older). The internal lubes were never meant to last that long, certainly without maintenance, and 'rubber' doesn't 'age well' either, thus requiring the above stated work. There's also the Akai Transport cams that need to be inspected for their degree of condition and replaced if necessary (difficult and potentially expensive). We've already inspected them for any detrimental issues. Ready to go now. Will play & Record stereo 1/4" tapes on reels up to 7". This is one of the few reel to reel decks we get in that make it to our finished page. If you're looking for a reel to reel deck to "actually use" then here you go. Only about 25% of the used Reel decks out there can be "practically" restored to working order. This one made it through. Playback & transport functions test great and records well! 8-Track, built-in amp and speakers all work great as well. Looks and sounds great too!

AKAI X-1810 Features include:


- 3 Motor design
(means less 'Rube Goldberg' mechanisms inside like many R2R's)
- DURABLE AC powered capstan motor (lasts decades longer than DC capstan motors of the 'later' models)
- 4-Speed
* Reel to Reel, 8-Track Cartridge deck w/ built-in speakers and amp
- Up to 7" reel capacity (while you could go down as far as 3" in diameter, the torque and braking on this deck has been optimized for 7"reels)
- Akai's "Cross-Field" Bias Head, gets the tape 'bias signal' off of the 'Record' head (so the 'Record Head' can be concentrated only on recording the 'music' signal) and biases with a separate head
- One-Micron Gap Recording Head (reel)

- Stereo or MONO playback / recording (reel tape) (means that in "MONO" mode, you can record 4 separate passes on a tape or playback tapes made on older decks that did 'four separate tracks')

- Quad speeds at
7.5 ips / 19cms (with included speed sleeve adapter), 3 3/4ips / 9.5 cms,1 7/8 ips / 4.8 cms & *15 ips / 38cms
- As it's got its own, Built-in Power amp and speakers, it can be used as a 'stand alone' unit. (very handy for a media transfer business setting up another 'station' without a stereo / audio system)

-
Spring loaded, Reel locks / Spindle tips (does not require rubber reel clamps / stoppers)
- Stereo playback / recording 8-Track Cartridge tape
- Auto-Reverse capable with 'sensing foil' installed (on correct side of tape)
- 'Manual-Reverse' at anytime with L & R selectors

- 'Continuous Play' or 'End of Tape Stop' for 8-Track
- S.R.T. Super Range Tape Equalization setting for recording
- Auto-Off for Reel deck
- Dual Analog VU meters
- Can also transfer from Reel tape to 8-Track Cartridge tape
*

- 8-Track 'Track Selector' w/ typical indicator lights
- Dual front mounted 1/4" Microphone inputs
- Front mounted 1/4" Headphone jack
- RCA and DIN I/O's
- Separate L&R Input / Volume controls
- Separate L&R Tone controls (for built-in amp)

- Internal Speaker On/Off switch (Auto switches when using 'External' speakers)


- NOT an OFFICIAL feature, BUT one function this deck will allow is a sort of CUE by slightly pushing up on the 'pause' lever, while the deck is in play, you can get a 'variable speed' CUE function. You'll either need to very gradually release the pressure or with your other hand move the 'Play' lever to 'Stop' when you reach the spot you wanted to 'cue to' or the tape will track off the front edge of the pinch roller. Takes a bit of practice to get it right.

- ANOTHER 'UN-OFFICIAL' feature of this deck is that due to it's internal 'brake' design, it's possible to 'SCRATCH' the tape across the playback head forward or backward! Just like with a DJ turntable!


(*15 ips ONLY w/ optional speed sleeve / pinch roller kit (not typically avail. The 15ips was utilized for transferring Reel tape signals to the 8-Track tape. While the Reel deck could record at 15ips, there's not a 15ips Tape EQ setting, which may or may not be detrimental to your needs)

-True "WORLD AC POWER" allows unit to be operated on 50 or 60 Hz AC and will select voltages from 110v, 120v, 220v and 240 volts AC input.

This is only about the third AKAI X-1810 we have restored in ~24 years. Great machine for playback / archiving your tapes to CD or Hard Drive or for recording new tapes. This is a clean deck. Performs very well following extensive refurbishing.
The vinyl wrapped, wood-grained case is in great 'structural' and decent cosmetic condition with only the above mentioned finish chips. The decks face, knobs, covers and all cosmetics are fabulous!
This machine would really be great for a 'media transfer' business or for someone who has a lot of tapes to preview prior to sending for transfer, or for a library or university with a lot of tapes of different speeds / and track formats to transfer. Of course it would also be great for anyone wanting to add an 'all purpose' reel to reel to their system. If your interest is primarily to 'record 8-tracks', I would simply choose a much simpler, '8-track only' deck that records better and would be less money.
Measures 17.5" wide x 18" tall x 9.8" deep and weighs 47 lbs unpacked. Comes with a pdf 'e' copy of Akai X-1810 / X-1810 owners manual and original brochure. Can include the AKAI X-1810 / X-1810 Service Manual pdf 'e' download if you wish as well. Includes our standard 90 day limited warranty.

 Our technician has completely gone through and 'Certified' this unit.

 
We have completely and extensively gone through the mechanicals and electronics of this unit.

 Entire transport was cleaned, de-greased, and re-lubed including; Pinch Roller Pivot Arm, EOT Sensor Arm, Left Tape Tension arm mechanism, Capstan Motor (clean and re-lube), Capstan and flywheel shaft removed cleaned / re-lubed (pretty much every moving part)

 Transport cams checked for usable condition prior to any work starting (here in the West, we have less of an issue with the typical deterioration that you see in more 'humid' climates such as the Mid-West, South and Coasts (be very careful getting an Akai from the early to mid 1970's that has spent most of it's life in a 'humid' environment).

 Entire 8-Track transport assembly was removed and disassembled for service, including burnishing it's connector, and track elevator / selector contacts.



 Voltage re-set to correct 120VAC

 Circuit board edge card contacts and connectors cleaned w/ solvent and burnished w/ fiberglass pen



 Tape Tension arms cleaned and re-lubed, and their springs adjusted

 Reel table height correct

 pinch-roller 'arm' mechanism completely disassembled, cleaned and re-lubed

 Capstan / flywheel removed, bushings and axles cleaned and re-lubed and flywheel burnished

 Capstan motor pulley burnished

 Capstan cleaned

 Rubber pinch roller removed and re-conditioned

 New MAIN drive belt, #42-550 installed

 Brand new counter belt, #042 installed

 Heads have been cleaned and de-magnetized as well as the entire transport (reel and 8-Track Cartridge).

 Brakes adjusted on fast wind modes at ALL points thru a tape. It's a fine line between having the brakes actuate with too much tension, 'abruptly' stopping the tape (risking stretching / breaking of tape) or too loose (allows tape to 'dump'). (VERY difficult to do on this series). Brakes optimized for 7" reels.

 Motor torque test perfectly. Following above adjustments, Reel Start and Stop tested at beginning, middle and end of 7" reels.

 Internal pots, switches (including linear record switch and 'rotary wafer' switches) and controls cleaned and tested for noise-free function (initially, of course, had typical static / noise which is to be expected in an 'un-serviced' deck after 45+ years) (also a bit easier on this "1810D than the "A-Type and B-Type X-1800SD" version. Just FYI).

 External / User adjustable pots, switches and controls cleaned on the playback / record amp and tested for noise-free function

(tech notes; Line out set to 0dB using 0dB reference @ 400Hz. Vol controls @ approx 1:30)

 Replaced VU meter lamps / bulbs #25-080

 We adjusted the VU meters mechanically and electronically w/ factory test tone tapes, as well as the internal playback levels for both directions independently and record levels.

 We adjusted the output, 'Minimum Input', 'Specified Input', 'Record Level' and 'Bias' all to spec, then further adjusted 'Bias' for Sony or Scotch "150", but Ampex 456 really shines.

 Both spindles in perfect alignment.

 Heads in great shape as well, with many years of performance left in them

 Alignment / azimuth was adjusted for peak performance on Playback and Record Heads on both the R2R and the 8-Track with factory test tone tape and oscilloscope.

 "X-Field / Bias" head had it's clearance checked / adjusted w / feeler gauges.

 Slightly noisy tape guide bearing replaced

 Repaired both 'Manual' Auto-Reverse switches

 Following initial restoration tests, we found we would have a channel drop out after playing for a while or when changing directions, and traced it to contact issues in the relays, thus the following operation...

 Both Play and Record relays (RL0201 & RL0202) had their contacts burnished on the 'Direction Change' PCB (not an easy task. Then tested 4 Hours with multiple manual reverses)

 Speed tested to 98.0% accuracy following refurb (meaning that our 'verified' 1000Hz test tape now plays back at 980Hz +/- 2Hz. (within spec).
 
 Adjusted to record sonically well* with the following results w/ Input at ~ 9:00 when recording, then Output control re-set to ~"2:00 PM" for playback.

 'Real World, DDD CD recorded sounds great w/ more *quality tapes such as Maxell UD-35, TDK Audua, or Ampex GM456 rather than say Scotch 150 or Sony 150 etc.


 'Electronic' Floor noise measured at >-52dB w/ blank tape, L&R.

 Depending on the impedance of any headphones utilized with the unit, the volume can be lower they would be expected thru the headphone output.

 Motor was disassembled, had front and rear bushings cleaned and re-lubed w/ 30W. VERY quiet now.

 This AKAI X-1810D functions, plays, and records VERY WELL (and we really put them through the paces, testing both with well mixed, recently recorded CD material and CD recorded / factory test tones looking for correct head Azimuth and speed accuracy).  (Total time investment in refurb process / and final testing ~ 26 hours).

The AKAI X-1810D Stereo Reel to Reel tape deck. Ready to GO! This is one of the few reel to reel decks we get in that make it to our finished page. Great performer. If you're looking for a reel to reel deck to "actually use" here you go. Only about 25% of the used Reel decks out there can be "practically" restored to working order. This one made it through with flying colors after about 26 hours of bench time.

Following mechanical / electronic refurb, entire unit was cosmetically detailed inside and out. Face is made of flat-black finished, aluminum and is dent free and in great condition. Really no cosmetic issues to mention. Deck looks and sounds great!

 Our technician has completely gone through and 'Certified' this unit for PLAYBACK*.

 
We have completely and extensively gone through the mechanicals and electronics of this unit.

 Entire transport was cleaned, de-greased, and re-lubed including; Pinch Roller Pivot Arm, EOT Sensor Arm, Left Tape Tension arm mechanism, Capstan Motor (clean and re-lube), Capstan and flywheel shaft removed cleaned / re-lubed (pretty much every moving part)

 Transport cams checked for usable condition prior to any work starting (here in the West, we have less of an issue with the typical deterioration that you see in more 'humid' climates such as the Mid-West, South and Coasts (be very careful getting an Akai from the early to mid 1970's that has spent most of it's life in a 'humid' environment).

 Entire 8-Track transport assembly was removed and disassembled for service, including burnishing it's connector, and track elevator / selector contacts.



 Voltage re-set to correct 120VAC

 Circuit board edge card contacts and connectors cleaned w/ solvent and burnished w/ fiberglass pen



 Tape Tension arms cleaned and re-lubed, and their springs adjusted

 Bent Reel spindle disassembled completely and center axle straightened on anvil

 Reel table height correct

 pinch-roller 'arm' mechanism completely disassembled, cleaned and re-lubed

 Capstan / flywheel removed, bushings and axles cleaned and re-lubed and flywheel burnished

 Capstan motor pulley burnished

 Capstan cleaned

 Rubber pinch roller removed and re-conditioned

 Main drive belt reconditioned

 Brand new counter belt, #041-042 installed

 Heads have been cleaned and de-magnetized as well as the entire transport (reel and 8-Track Cartridge).

 Brakes adjusted on fast wind modes at ALL points thru a tape. It's a fine line between having the brakes actuate with too much tension, 'abruptly' stopping the tape (risking stretching / breaking of tape) or too loose (allows tape to 'dump'). (VERY difficult to do on this series). Brakes optimized for 7" reels.

 We adjusted the VU meters mechanically and electronically w/ factory test tone tapes, as well as the internal playback levels for both directions independently and record levels.

 Both spindles in perfect alignment.

 Heads in great shape as well, with many years of performance left in them

 Alignment / azimuth was adjusted for peak performance on Playback and Record Heads on both the R2R and the 8-Track with factory test tone tape and oscilloscope (** still no appreciably positive effect on recording quality).

 "X-Field / Bias" head had it's clearance checked / adjusted w / feeler gauges. (**still no appreciably positive effect on recording quality).

 "X-Field / Bias" head had it's impedance measured at ~2.1-2.2 Ohms, which is what others measure at. (** still no appreciably positive effect on recording quality).

 Slightly noisy tape guide bearing re-lubed with 'heavier' lubricant to quiet operation

 Disassembled and cleaned both 'Manual' Auto-Reverse switches

 Following initial restoration tests, we found we would have a intermittent 'auto-reverse', and traced it to contact issues in the relays, thus the following operation...

 Both Play and Record relays (RL0201 & RL0202) had their contacts burnished on the 'Direction Change' PCB (not an easy task. Then tested 4 Hours with multiple manual reverses)

 Auto-Shut-Off switch cleaned for trouble-free operation (was definitely causing trouble prior to cleaning)

 Speed tested to 99.8% accuracy following refurb (meaning that our 'verified' 1000Hz test tape now plays back at 1000Hz +/- 2Hz. (VERY much within spec).
 
 **Will actually record to a 'usable' level following these tips;
So you can actually make 'usable' recordings on it. You'll have to record at 7.5ips, push the levels more than you normally would into the 'Red', and Record with the EQ setting for 7.5ips. Then Playback with the 'Output' controls set much higher, and the EQ then set to 1 7/8 ips. The playback is decent, just not up to our normal standards. To get the best results, we would recommend Ampex GM-456 or similar, high quality tape. Same technique applies to the 8-Track, except EQ is not used with the 8-Track deck.


 'Electronic' Floor noise measured at >-52dB w/ blank tape, L&R.

 Also following initial refurb, we thought the main cap motor was noisier than it should be, so entire deck was again, removed form housing, and stripped to allow access to Motor, which was then disassembled, had front and rear bushings cleaned and re-lubed w/ 30W. We also changed the cooling fan to a modified unit to reduce 'fan / air' noise at 7.5 ips speed. VERY quiet now.

 Internal, built-in amp and speakers all work fine. Nothing needed for that aspect.

 This AKAI X-1810D PLAYS VERY WELL from the reel to reel section and the 8-Track cartridge section using factory test tones, looking for correct head Azimuth and speed accuracy.  (Total time investment in refurb process / and final testing ~ 30+ hours. OUCH!).

The AKAI X-1810D Stereo Reel to Reel tape deck. Ready to GO! This is one of the few reel to reel decks we get in that make it to our finished page. Great deck for 'Playback' use. As eluded to above, we were not able to get the 'recording capabilities' of either the R2R or the 8-Track Cart aspect up to standard, so again, this deck is for 'Playback' use. This one made it through after about 30+ hours of bench time.

Following mechanical / electronic refurb, entire unit was cosmetically detailed inside and out. Face is made of flat-black finished, aluminum and is dent free and in great condition (except for an additional port / hole in the lower section and a finish chip on the lower, right edge of the case). Really few issues to mention. Deck looks and plays great!

Looks great & "Ready-to-go", for PLAYBACK, AKAI X-1810D Stereo Reel to Reel tape deck. Very 'famous' and popular reel tape deck. Probably half the folks stationed overseas in the military during Viet Nam that purchased a Reel to Reel came back with an 1800 series. Unfortunately of course, 45 years has not been kind to Akai Reel decks (or any electro-mechanical devices that are 20 years old or older). The internal lubes were never meant to last that long, certainly without maintenance, and 'rubber' doesn't 'age well' either, thus requiring the above stated work. There's also the Akai Transport cams that need to be inspected for their degree of condition and replaced if necessary (difficult and potentially expensive). We've already inspected them for any detrimental issues. Ready to go now. Will play & Record stereo 1/4" tapes on reels up to 7". This is one of the few reel to reel decks we get in that make it to our finished page. If you're looking for a reel to reel deck to "actually use" then here you go. Only about 25% of the used Reel decks out there can be "practically" restored to working order. This one made it through. Playback & transport functions test great and records well! 8-Track, built-in amp and speakers all work great as well. Looks and sounds great too!
Another note I'd like to make is that the 8-Track is among the BEST I've auditioned for playback (and we've restored and sold A LOT of 8-Track decks 'as vintage', and I sold them when NEW as well).

AKAI X-1810 Features include:


- 3 Motor transport
(means less 'Rube Goldberg' mechanisms inside like many R2R's)
- DURABLE AC powered capstan motor (lasts decades longer than DC capstan motors of the 'later' models)
- 4-Speed
* Reel to Reel, 8-Track Cartridge deck w/ built-in speakers and amp
- Up to 7" reel capacity (while you could go down as far as 3" in diameter, the torque and braking on this deck has been optimized for 7"reels)
- Built-In Amp and Speakers for listening WITHOUT a stereo / sound system if desired
- Akai's "Cross-Field" Bias Head
- One-Micron Gap Recording Head (reel)

- Stereo or MONO playback (reel tape) (means that in "MONO" mode, you can playback 4 separate passes on a tape for playback of tapes made on older decks that did 'four separate tracks')

- Quad speeds at
7.5 ips / 19cms (with included speed sleeve adapter), 3 3/4ips / 9.5 cms,1 7/8 ips / 4.8 cms & *15 ips / 38cms
-
Spring loaded, Reel locks / Spindle tips (does not require rubber reel clamps / stoppers)
- Stereo playback / recording 8-Track Cartridge tape
- Auto-Reverse capable with 'sensing foil' installed (on correct side of tape)
- 'Manual-Reverse' at anytime with L & R selectors

- 'Continuous Play' or 'End of Tape Stop' for 8-Track
- S.R.T. Super Range Tape Equalization setting
- Auto-Off for Reel deck
- Dual Analog VU meters

- 8-Track 'Track Selector' w/ typical indicator lights
- Dual front mounted 1/4" Microphone inputs
- Front mounted 1/4" Headphone jack
- RCA and DIN I/O's
- Separate L&R Input / Volume controls
- CUE monitoring in 'fast wind' mode at a moderate volume

- NOT an OFFICIAL feature, BUT one function this deck will allow is a sort of CUE by slightly pushing up on the 'pause' lever, while the deck is in play, you can get a 'variable speed' CUE function. You'll either need to very gradually release the pressure or with your other hand move the 'Play' lever to 'Stop' when you reach the spot you wanted to 'cue to' or the tape will track off the front edge of the pinch roller. Takes a bit of practice to get it right.

- ANOTHER 'UN-OFFICIAL' feature of this deck is that due to it's internal 'brake' design, it's possible to 'SCRATCH' the tape across the playback head forward or backward! Just like with a DJ turntable!

- Separate L&R Tone controls

-True "WORLD AC POWER" allows unit to be operated on 50 or 60 Hz AC and will select voltages from 110v, 120v, 220v and 240 volts AC input (currently set for proper power for North America).

This is only the third AKAI X-1810 we have restored in ~24 years. Great machine for playback / archiving your tapes to CD or Hard Drive. This is a beautiful deck. Performs incredibly well following extensive refurbishing for PLAYBACK.
The vinyl wrapped, wood-grained case is in great 'structural' and cosmetic condition with only a few issues worth mentioning. One, there's a Formica / finish chip on the lower, right edge of the case. Two, someone added an access port to the front panel, near the 'selector' switches for?. Three, there's a bit of surface corrosion on the rear, lower edge of the black, metal panel. There's also a bit of aluminum corrosion on the lower, front trim piece. Along the sides of the wood housing, are 2 holes from being 'rack mounted' in the past (see photos above). Overall the decks face, knobs, covers and all cosmetics are in good condition.

This machines 'Forte' would really be best suited for a 'media transfer' business, especially where you have a bench / station that doesn't have dedicated sound system (as it's go it's own, built-in amp and speakers) or for someone who has a lot of tapes to preview prior to sending for transfer, or for a library or university with a lot of tapes of different speeds / and track formats to transfer. If you're going to be listening to 'quiet, chamber' music while reading, the "AC powered" motor / fan noise could be distracting while 'casually' listening to quiet passages of music. If you tend to like the volume at more than 'low, back ground' levels, then you'll not likely notice "AC powered motor" hum (mechanical only and does not transfer into the 'signal' of the unit).

Measures 17.5" wide x 18" tall x 9.8" deep and weighs 47 lbs unpacked. Comes with a pdf 'e' copy of Akai X-1810 owners manual and original brochure. Can include the AKAI X-1810 Service Manual pdf 'e' download if you wish as well. Includes our standard 90 day limited warranty.

SHIPPING TO JOEL IN NEW JERSEY

as a 'PLAYBACK' unit

**OK, so you CAN actually make 'usable' recordings on it. You'll have to record at 7.5ips, push the levels more than you normally would into the 'Red', and Record with the EQ setting for 7.5ips. Then Playback with the 'Output' controls set much higher, and the EQ then set to 1 7/8 ips. Same process and results for the 8-Track cartridge deck, except ignore the 'EQ' portion. The playback IS decent, just not up to our normal standards.

(Reels shown in photos are not included, but we sometimes / occasionally have them for sale. Inquire at time of order.
However, all of our decks will come with 2x tapes for testing 'Playback' and 'Recording' as well as a 7" 'take-up' reel, and RCA patch cables for connection to your system)

 Our technician has completely gone through and 'Certified' this unit.

 
We have completely and extensively gone through the mechanicals and electronics of this unit.

 Entire transport was disassembled down to the chassis, and every mechanical part was cleaned, de-greased, and re-lubed including; Pinch Roller Pivot Arm, EOT Sensor Arm, Left Tape Tension arm mechanism, Capstan Motor (clean and re-lube), Capstan and flywheel shaft removed cleaned / re-lubed (pretty much every moving part)

 Transport cams checked for usable condition prior to any work starting (here in the West, we have less of an issue with the typical deterioration that you see in more 'humid' climates such as the Mid-West, South and Coasts (be very careful getting an Akai from the early to mid 1970's that has spent most of it's life in a 'humid' environment).

 Entire 8-Track transport assembly was removed and disassembled for service, including burnishing it's connector, and track selector contacts.

 Voltage re-set to correct 120VAC

 Circuit board edge card contacts and connectors burnished w/ solvent and fiberglass pen

 Tape Tension arms disassembled, cleaned and re-lubed, and their springs adjusted

 Reel table height correct

 pinch-roller 'arm' mechanism completely disassembled, cleaned and re-lubed

 Capstan / flywheel removed, bushings and axles cleaned and re-lubed and flywheels burnished

 Capstan motor pulley burnished

 Capstan cleaned (as well as the internal and external surfaces of the original speed sleeve)

 ALL Internal idler tires cleaned / reconditioned

 Rubber pinch roller removed and re-conditioned

 New MAIN drive belt, #42-550 installed

 Brand new counter belt, #048 installed

 Heads have been cleaned and de-magnetized as well as the entire transport (reel and 8-Track Cartridge).

 Brakes adjusted on fast wind modes at ALL points thru a tape. It's a fine line between having the brakes actuate with too much tension, 'abruptly' stopping the tape (risking stretching / breaking of tape) or too loose (allows tape to 'dump'). (VERY difficult to do on this series). Brakes optimized for 7" reels.

 Motor torque test perfectly. Following above adjustments, Reel Start and Stop tested at beginning, middle and end of 7" reels.

 Internal pots, switches (including linear record switch and 'rotary wafer' switches)and controls cleaned and tested for noise-free function (initially, of course, had typical static / noise which is to be expected in an 'un-serviced' deck after 45+ years) (also a bit easier on this "Type-C" version. Just FYI).

 External / User adjustable pots, switches and controls cleaned on the playback / record amp and tested for noise-free function

(tech notes; Line out set to 0dB using 0dB reference @ 700Hz. Vol controls @ approx 1:30)


 Replaced VU meter lamps / bulbs #25-450

 Cleaned 8-Track cartridge heads

 We adjusted the VU meters mechanically and electronically w/ factory test tone tapes, as well as the internal playback levels for both directions independently and record levels.

 We adjusted the output, 'Minimum Input', 'Specified Input', 'Record Level' and 'Bias' all to spec, then further adjusted 'Bias' for Ampex GM-456

 Both spindles in perfect alignment.

 Heads in great shape as well, with many years of performance left in them

 Playback and Record Head alignment / azimuth was adjusted for peak performance with factory test tone tape and oscilloscope.

 Speed tested to 98.8% accuracy following refurb (meaning that our 'verified' 1000Hz test tape now plays back at 988Hz +/- 2Hz. {well within spec by 18Hz}).
 
 Adjusted to record VERY WELL. Biased for Ampex GM 456 studio tape with the following results w/ Input at ~ 9:00 when recording, then Output control ~"2:00 PM" for playback.

 'Real World, DDD CD recorded sounds great w/ Ampex GM456.


 'Electronic' Floor noise measured at >-60dB w/ blank tape, L&R.

 Motor had a slight amount of run-out detected at the belt pulley (side to side movement / play) which causes excessive, ambient noise, so we swapped it with another of the exact motor (we had a 'donor unit'), which was then also, completely disassembled, cleaned and lubed w/ 30W.

(tech notes; internal amp tests well w/ ~ 1mVDC across outputs w/ 8 Ohm load. Also as a side note, the Akai X-1800SD C-Type utilizes the same output transistors as the later Akai X-1810.
)

 This AKAI X-1800SD functions, plays, and records VERY WELL (and we really put them through the paces, testing both with well mixed, recently recorded CD material and CD recorded / factory test tones looking for correct head Azimuth and speed accuracy).  (Total time investment in refurb process / and final testing ~ 21 hours).

The AKAI X-1800SD Stereo Reel to Reel tape deck. Ready to GO! This is one of the few reel to reel decks we get in that make it to our finished page. Great performer. If you're looking for a reel to reel deck to "actually use" here you go. Only about 25% of the used Reel decks out there can be "practically" restored to working order. This one made it through with flying colors after about 21 hours of bench time.

Following mechanical / electronic refurb, entire unit was cosmetically detailed inside and out. Face is made of aluminum and is dent free and in great condition. Cabinet covered in real TEAK wood veneer, is in decent condition with just a few 'battle scars', checking / fading to the finish (see photos above) and just had a fresh coat of Howards 'Restore a Finish' and followed Howards 'Feed-n-Wax'. All the case hardware intact and working, and had all it's fasteners torqued down. Deck looks and sounds great!

AKAI X-1800SD Features include:


- 4-Speed
* Reel to Reel, 8-Track Cartridge deck w/ built-in speakers and amp
- DURABLE AC powered capstan motor (lasts decades longer than DC capstan motors of the 'later' models)

- Up to 7" reel capacity (while you could go down as far as 3" in diameter, the torque and braking on this deck has been optimized for 7"reels)
- Akai's "Cross-Field" Bias Head, gets the tape 'bias signal' off of the 'Record' head (so the 'Record Head' can be concentrated only on recording the 'music' signal) and biases with a separate head
- One-Micron Gap Recording Head (reel)

- Stereo or MONO playback / recording (reel tape) (means that in "MONO" mode, you can record 4 separate passes on a tape or playback tapes made on older decks that did 'four separate tracks')

- Quad speeds at
7.5 ips / 19cms (with included speed sleeve adapter), 3 3/4ips / 9.5 cms,1 7/8 ips / 4.8 cms & *15 ips / 38cms (requires optional 15ips kit, not available from us.
- As it's got its own, Built-in Power amp and speakers, it can be used as a 'stand alone' unit. (very handy for a media transfer business setting up another 'station' without a stereo / audio system)
- Stereo playback / recording 8-Track Cartridge tape
- Continuous Play or 'End of Tape' Stop for 8-Track (however at this point the 'Auto-Stop' does not seem to recognize the 'sensor' tape on 8-tracks so only does "Continuous Play" at the end of track #4)
- 8-Track 'Track Selector' w/ typical indicator lights
- Auto-Off for Reel deck
- Can also transfer from Reel tape to 8-Track Cartridge tape
*
- Built-in 'Tape Cleaner' pad (can also lube 'back coated' tapes so they don't squeak if you can obtain the correct silicone lube. No, we don't know where to get it at this point...yet)
- Dual front mounted 1/4" Microphone inputs
- Side mounted 1/4" Headphone jack
- RCA and DIN I/O's
- Separate L&R Input / Volume controls
- Separate L&R Tone controls (for built-in amp)

- Internal Speaker On/Off switch (Auto switches when using 'External' speakers)

- NOT an OFFICIAL feature, BUT one function this deck will allow is a sort of CUE by slightly pushing up on the 'pause' lever, while the deck is in play, you can get a 'variable speed' CUE function. You'll either need to very gradually release the pressure or with your other hand move the 'Play' lever to 'Stop' when you reach the spot you wanted to 'cue to' or the tape will track off the front edge of the pinch roller. Takes a bit of practice to get it right.


(*15 ips ONLY w/ optional speed sleeve / pinch roller kit (not typically avail. The 15ips was utilized for transferring Reel tape signals to the 8-Track tape. While the Reel deck could record at 15ips, there's not a 15ips Tape EQ setting, which may or may not be detrimental to your needs)

-True "WORLD AC POWER" allows unit to be operated on 50 or 60 Hz AC and will select voltages from 110v, 120v, 220v and 240 volts AC input.
