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.

SHIPPING TO KEN IN GEORGIA

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

 We have completely and EXTENSIVELY gone through the mechanicals and electronics of this unit (and this was a BIG project as it's a VERY complex deck).

 Initially FS702 would blow when transport engaged. Found bad D702 rectifier and bad IC802. Replaced both to cure issue. Now all power supply Voltages correct.

 Initially had intermittent record issues, especially with one channel. Found both Omron "GTVN-234P / 24VDC" (R301 & R401) relays were occasionally intermittent. Replaced with NEW, correct, Omron OEM relays.

 Via extensive testing of all the systems and system combinations, we found bad and questionable components / semi-conductors / transistors at call-out locations; Q408, IC302, & Q409

 Via Following the above mentioned replacements, there still remains an issue with recording when in the SOS / SWS mode. We chose not to continue to pursue those aspects as few users would ever need to record "Sound on Sound" or "Sound with Sound". There are other, easier, cheaper ways to do that nowadays.

 Transport mechanisms disassembled, cleaned, lubed w/ 'SuperLube', silicone based gel and light machine oil as necessary 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.

 Capstan motor disassembled. New oil felts fabricated and installed

 Rubber pinch and impedance rollers removed, re-surfaced, conditioned and re-installed with fresh lubricant

 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)

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

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

 All four meter lamps replaced with #25-450 bulbs

 Both spindles in perfect alignment.

 We also checked / 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 / Phase was adjusted for peak performance with factory test tone tape and oscilloscope.

 Speed tested to 99.9+% accuracy following refurb with pitch control defeated or "Off" (meaning that our 'verified' 1000Hz test tape now plays back at 1000 +/- 1Hz) (separate, internal adjustments for each of the three speeds were addressed).
 
 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 multiple Tapes, ie; Scotch 207, Maxell XL-II, Ampex GM456, ATR, and Ampex 499. Tech noted, "Best I've ever heard").

 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 Otari MX5050B-II 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).  


 Recording tests performed with the following tapes and results:

Scotch 207
tape. Heres how it tested at 0dB; 1kHz / L= ~-1.75dB & R= ~-1.75dB
Maxell UDXL-II
tape. Heres how it tested at 0dB; 1kHz / L= ~-2.75dB & R= ~-2.75dB
ATR
tape. Heres how it tested at 0dB; 1kHz / L= ~0dB & R= ~0dB
Ampex GM456
tape. Heres how it tested at 0dB; 1kHz / L= ~0dB & R= ~0dB
Ampex GM499 tape. Heres how it tested at 0dB; 1kHz / L= ~0dB & R= ~+.75dB

 (Total time investment in refurb / testing ~ 42+ hours).

This is an fabulous deck for both recording or playback, again of 'Half-Track / 2-Track' tapes and playback of standard, 4-Track/2-Channel tapes AND for speeds of 3.75ips, 7.5ips or 15ips. Following refurbishment, the deck looks and works great and sounds amazing!!! 

As this deck plays 2 different tape formats and 3 speeds, it would make a great 'One-Size-Fits-Most' deck for a media tape transfer house as well.

The Otari MX5050B-II Stereo 'Half-Track / 2-Channel' / 'Quarter-Track / 2-Channel', 1/4" wide Reel to Reel tape deck. Ready to GO! First one of these we've had in 30+ years of dealing in vintage audio. This is one of the few reel to reel decks we get in that make it to our finished page. Following our refurb / bench time it's now an AMAZING performer (Check the 'recording test results' above and the 'specs' in larger 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 41+ hours of bench time.

The deck tests great! Cosmetically it's in good condition. Looks good and sounds great ! We have completely gone through it. Will play up to 10.5" reels.

Otari MX5050B-II Features include:

- Half-Track / 2-Track / 2-Channel Stereo head stack / tape format for recording and playback and additionally a 4-Track / 4-Channel head-stack for playback of standard, commercially recorded tapes.
- 3 Heads for instant monitoring of tape levels while recording
- Up to 10.5" Max Reel Capacity (The BIG Reels!)
- Direct Capstan drive...YEA, NO belt to worry about! (NO 'Counter' belt required either!)
- Built-in Test Tone Oscillator for Bias, Recording Level / Tape Type adjustments and head adjustments (1kHz and 10kHz generator)
- Fixed or Completely variable Bias adjustment (owners manual includes a chart with suggested Bias settings for most contemporary tape types / brands / models, but I prefer to do it 'by ear')
- Completely variable Playback Tape EQ adjustment (owners manual includes a chart with suggested EQ settings for most contemporary tape types / brands / models, but I prefer to do it 'by ear')
- 3 Motors (means less 'Rube Goldberg' mechanisms inside like many R2R's)
- Solenoid tape transport for "Touch" control
- Triple speeds at 15ips / 38cms, 7.5 ips / 19cms & 3.75 ips / 9.5cms (switchable internally between 15/7.5 & 7.5/3.57 pairs)
- Sound-on-Sound / Sound-with-Sound / Punch In / Punch Out capabilities (SOS & SWS is essentially inoperative due to further circuitry issues we were not able to resolve as it wasn't monetarily practical. The chance that anyone would need those functions from the deck is "slim to none".)
- Very 'Serviceable' internal design with either 'swing In/Out' cards or detachable connectors

- Cue Lever for lifting tape away from head in Fast Wind modes or for moving tape close enough to head to monitor fast wind progress
- Input (Source) / Repro (Monitor) selector independently for each channel
- Output level control for each channel
- Low or High output ranges (selectable on rear panel)
- IEC or NAB Equalization (selectable on rear panel)
- Low / Mid / High Flux Reference level (selectable on rear panel)

- Dual analog VU level meters w/ LED 'Peak' indicators
- Digital Tape Counter w/ "Memory Stop" function
- XLR Line & MIC I/O's for all channels
- Dual Microphone inputs with 20dB attenuators
(selectable on rear panel)
- Ground connector on rear panel for reducing / addressing 60Hz hum
- Rack mountable with optional ears
- Can be used in either 'Vertical' or laying back, all the way to 'Horizontal'
- Accessory connectors for optional Otari Remote control
- Tape 'Splice Block' located on the head cover


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 99.9% 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. Again, check the 'test results' listed above). Pinch rollers and heads all in GREAT condition!!! Very clean and GREAT!

As I mentioned earlier it's about as 'Swiss Army' knife as you could get. It can do 3 speeds from 3 3/4ips to 15ips, AND can play 2-Track or 4-Track tapes. We've had other decks that can do one of those two options, but never one that can do BOTH!!! This is a GREAT deck with UNBELIEVABLE PERFORMANCE. I think it is now my favorite model of Reel to Reel deck (at least among the many dozens I've had over the past 3 decades). Probably the best sounding deck I've had the pleasure to audition due to the built in oscillator, fine bias and variable EQ alone.
Again, as mentioned earlier, cosmetically it's in great condition.
This was
considered a 'standard' among studio engineers. A real 'Workhorse' throughout much of the 1980's into the '90's.

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.

 Flywheel / capstan removed, bushings cleaned and re-lubed when re-assembled.

 Capstan cleaned / burnished

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

 All three internal drive tires / wheels resurfaced on drill-press, then reconditioned for positive grip

 We discovered that one of the idler wheels had a bronze bushing that with enough wear that caused excessive mechanical noise. We replaced it with an original / OEM wheel from another TC-377 we had and re-conditioned it. Now the entire deck is quite as it should be.

 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 reel tables removed, disassembled, clutch pads resurfaced, then reassembled and tensioned correctly

 Both spindles in perfect alignment.

 We also adjusted the reel table heights for tighter fitting reels, and no 'flange rub' by adding a layer of rubber under the original table mats (assuming you're installing reels that are also 'running true')

 Pinch roller reconditioned / re-surfaced.

 Mains AC cord replaced

 Power supply board tested to it's intended +25VDC. We had full voltage to the record amplifier and was able to adjust record amp to intended levels.

 New VU meter illumination lamp installed (#25-090) and both record indicator lamps test fine.

 Internal 'Line Level', '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.

 Plays and Records GREAT both channels


Records GREAT @ 0dB / 1kHz on High Bias tape (Ampex GM456 and / or ATR Tape) w/ L=~+2dB and R=~+2dB. Recorded program material SOUNDS FANTASTIC!!!

 Speed checked once 'warmed up', to 99.1% accuracy. (Meaning a 'factory' 1kHz tape plays back at 991Hz. (tech note: has Sony 60Hz / #0 motor pulley installed from factory)

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

Again, Pinch roller and F&F Heads all in GREAT condition.

(Total time investment in refurb / testing
~ 17.5 hours).

Cosmetically there's a few striations in the upper, left corner of the face, the lower, left corner and circular 'witness marks' from metal reels being 'stopped by hand' at some point in it's life. There's also a small ding in the lower, left corner of the face (see photos above of details).

(one of the most important features on a deck in our opinion. Allows you to match volume level of other sources, allows adjustment for 'best' pre-amp input to avoid distortion, allows you to change the volume of the deck if you have it located remotely from the pre-amp / receiver as I do, and many other applications)
- Lockable Pause "Inst-Stop" lever
- Mic Attenuator selector
- RCA inputs and outputs
- Spring loaded tape hub spindles (no need for rubber reel retainers)
- Can be mounted in cabinet for 'vertical' orientation (as currently installed) or inverted for 'horizontal' use.

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. Tapes made on this type of 'tape deck / head / track format' will play on a '4-Track / 2-Channel' deck to a 'usable' degree for the most part (we've done it). You simply 'mute / turn-down / disconnect' one side or the other from the playback deck.

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...

CIRCA MID 1960'S
MIJ
RESTORATION PROJECT / REFURB CANDIDATE / AS-IS

for sale

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 good Fast Forward and Re-Wind function at decent speed at most or all locations on a 7" reel
- Capstan turns
- Counter functions
- Tape plays / sounds decent
- Tape deck does record surprisingly well for an 'As-Found' deck (includes a tape we just recorded on it)
- 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 a few cracks on some, but are serviceable IMO (we certainly would have no issue reconditioning them with full faith)
- Heads appear to be in good condition (see above photos)
- 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)
- No apparent missing parts
- Mostly original NEC tubes with a couple of American GE tubes
- Internal Tube Amp sounds decent from both L & R
- External Speakers both function well
- All I/O jacks works well

Sony TC-500A Features:

- All Tube Electronics
- Original Specified Tube Compliment; 2X 12AD7 (or 12AX7), 2x 6AU6, 2X 6AQ5, 1x 12BH7A, 1x 6CA4 (at least one "12AU7" has been installed in-place of the 12AD7)
- Point to Point wiring
- Built-In Stereo Tube Amplifier
- Can work as a PA system as well
- Mix Microphone input with Line Input signal (great for 'singing along' into recordings)
- Back-Lit, Analog, Level Meters

- Variable Output / Volume control
(one of the most important features on a deck in our opinion. Allows you to match volume level of other sources, allows adjustment for 'best' pre-amp input to avoid distortion, allows you to change the volume of the deck if you have it located remotely from the pre-amp / receiver as I do, and many other applications)
- Dual Mic / Line level controls
- Auto stop for play and fast wind functions

- "Inst Stop" to reduce backlash when in FF mode
- Analog Tape Counter
- Pause control

- Dual, 4.5" driver Speakers fold up onto case for a portable unit (about a 60 lb "portable unit")
- RCA and DIN I/O jacks
- Dual front mounted " Microphone inputs
- External, 1/4" Speaker jacks
- External Line Fuse
- Dual AC convenience outlets

-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.

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 1/27/2021
SHIPPED TO GEORGE IN FLORIDA

  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.

 Capstans burnished

 Impedance roller removed, bushings and axels cleaned and re-lubed

 Rubber pinch rollers have been properly resurfaced and then re-conditioned

 Brand new counter belts installed #040 & #042

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

 Power supply CB adjusted to correct 24VDC which enables best performance from Cap motor, Playback and Record amp circuits (slightly low Voltage was originally causing a slight 'low record' situation on the left channel. Also repaired shorted diode on 'Servo' cb.

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 VU meters electronically w/ factory test tone tapes, as well as the internal playback and record levels.

 Deck has been fully calibrated to factory manual specs, tested, and found to perform great.

Both spindles in great alignment.

 Slight 'flutter' issue was improved by 'truing' capstan more accurately

 We also adjusted the reel table heights.

 Heads have virtually no appreciable, visible wear.

  Recording tests performed with Maxell UDXL-II tape. Heres how it tested at 0dB; 1kHz / L= ~-1.5dB & R= ~-1.75dB

  Floor noise measured at >-60dBm

 This Akai GX-630D 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 ~ 16.5+ hours).

 Face is made of beautiful brushed aluminum and is in great condition. Deck looks and works great!

SOLD 2/3/2021
SHIPPED TO DAVID IN MARYLAND


This unit has its fair share of 'battle scars' and up close, isn't going to win any beauty contests, but...

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.

 Capstans burnished

 Impedance roller removed, bushings and axels cleaned and re-lubed

 Rubber pinch rollers have been properly resurfaced and then re-conditioned

 Brand new counter belts installed #039 & #042

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

 Missing skids replaced with 'oversize' feet.

 Replaced AC line cord

 Originally missing 'Monitor' switch replaced with an original / OEM switch from another GX-630D.

 Power supply CB adjusted to correct 24VDC which enables best performance from Cap motor, Playback and Record amp circuits (slightly low Voltage was originally causing a slight 'low record' situation on the left channel. Also repaired shorted diode on 'Servo' cb.

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 VU meters electronically w/ factory test tone tapes, as well as the internal playback and record levels.

 Deck has been fully calibrated, tested, and found to perform well.

Both spindles in decent alignment. The 'Supply' spindle has a bit of run-out, but nothing that affects performance.

All 4 tape guides rotated 180 degrees to present 'fresh' surface to tape.

 Slight 'flutter' issue was improved by 'truing' capstan more accurately

 'Record' lamps replaced with new 24VDC bulbs

 We also adjusted the reel table heights.

 Heads have virtually no appreciable, visible wear.

Recording tests performed. Heres how it tested at 0dB;
with Maxell UDXL-II tape: 1kHz = ~-2.5dB L&R
with Ampex GM-456 tape: 1kHz = ~+1.5dB L & ~+0.5dB R
with TDK Audua tape: 1kHz = ~-3.5dB L & ~-2.5dB R

Speed tested to 99.8% accuracy with 1kHz factory test tape (meaning 1kHz calibration tape plays back at 1002Hz +/- 1Hz)

  Floor noise measured at >-60dBm

 This Akai GX-630D 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 ~ 30 hours).

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!
So there's a 'laundry list' of minor, cosmetic issues with this unit, and there's a separate photo collage above that shows them, but here's the list;
Wood grain, vinyl wrapped case has numerous chips / dings, and a nice cigarette burn on top. The face has crescent reel flange marks (those are actually fairly common on many machines). The pinch roller is missing it's hub cap. There some scratches under the capstan. The head cover has numerous scratches and some 'yellow' staining (wouldn't come off). There's some light corrosion under the meters on the aluminum bezels. The 'supply' reel spindle has the outermost, end of it's tip chipped off (still functionally fine). The rear vent panel, has been replaced with a non-original one. The originally missing skids have been replaced with oversize feet (actually a 'good thing').

 As touched on above, the heads are in beautiful condition. Spindle tridents are in great condition with strong springs, and no cracks, splits or broken spines.

Akai GX-630D Features include:

- 4-Track / 2-Channel
- Up to 10.5" Reel Capacity (compatible with standard / normal 4-Track / 2-Channel tape format, but could do some justice to 4-Track / 1-Channel or 2-Track / 1-Channel)
- 3 Heads for instant monitoring of tape levels while recording
- Three Motors for trouble free performance (has a lot to do with it still being a viable piece of gear due to less rubber parts)
- Direct Drive (no main drive belt to worry about)
- Auto-Reverse for Playback (when using tape with "auto-reverse" sensing foil) (Forward Recording, with forward & reverse playback)
- Dual speeds at 7.5 ips / 19cms and 3 3/4ips / 9.5 cms

 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 disassembled, cleaned, re-lubed and reassembled including; Both Tape Lifters, 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)

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




 Originally 'Frozen' pinch-roller 'pivot' mechanism heated for removal, completely disassembled, cleaned and re-lubed,

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

 Capstan burnished

  Rubber pinch roller removed and re-conditioned



 MAIN drive belt reconditioned and re-installed

 Brand new counter belt, #152 installed (FYI; requires removal of TU reel table trim, Top front Trim, and dismounting of Power Transformer)

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

 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.

 Re-lubed all 3 motors (all have 'oil tubes')

 Fabricated new 'oil slinger' for capstan shaft

 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" 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).

 Cleaned all 'user' slide switches and control pots

 Checked VU meter lamps / bulbs

 Power supply checked / tested for proper "23VDC" output and for 'ripple' on O'Scope.

 We adjusted all  four 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.

 We also adjusted the reel table heights for average reel flanges.

 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.

 Entire deck detailed inside and out cosmetically




 Speed tested to 99.6% accuracy following refurb (meaning that our 'verified' 1000Hz test tape now plays back at 1004Hz).

 Adjusted* to record VERY WELL using Fluke8060A allowing proper "DBV" measurements! Biased for Ampex GM 456 studio tape with the following results w/ Output control ~"2:00 PM":
1kHz recorded @ 0dB resulted in PB @ L=~+0.5dB & R=~-1dB
W/ Maxell UDXL-II; 1kHz recorded @ 0dB resulted in PB =~-3dB L&R


* Adjusted BOTH layers of 'Record Amp' circuit board. Most folks trying to service these are not aware that there's a 'top' layer for tracks 1&3 and therefore at best, only get the 'rear channels' / tracks 2&4 adjusted.

 'Real World, DDD CD recorded @ zero dB w/ GM456 Sounded fabulous

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

 This Teac A-2340R 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).

Face is beautiful, brushed, Stainless Steel and case is in LIKE NEW condition.

The Teac A-2340R 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 19.5 hours of bench time.

The deck tests great! Looks and sounds great too! We have completely gone through it. Will play 5" & 7" reels (would play small 2-5" to 3" as well).

Teac A-2340R Features include:

- 4-Track / 4-Channel / Quadraphonic, 4-Track / 2-Channel Stereo OR 4-Track / 1-Channel, head stack / tape format
- "SIMUL-TRACK" DOES 4 TRACK "HEADS-UP" RECORDING (meaning ALL four tracks at once)
- 3 Heads for instant monitoring of tape levels while recording
- 3 Motors for trouble free performance (has a lot to do with it still being a viable piece of gear due to less rubber parts)

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

- Solenoid tape transport for "Touch" control
- Analog tape counter
- Auto-Reverse capable with 'sensing foil' installed (on correct side of tape)
- 'Pause' control
- Dual speeds at 7.5 ips / 19cms and 3 3/4ips / 9.5 cms
- Four Separate dual mic and line level controls
- Four 1/4" front mounted mic inputs
- Four Input & Four Output RCA connectors
- Four Source / Monitor selectors
- Four Output level controls
- QUAD analog VU level meters
- Dual / Front-Rear 1/4" front mounted headphone outputs (works w/ 'Quadraphonic' headphones as well)
- Four Dual position tape REC Bias type selector
- Spring loaded tape hub spindles (no need for rubber reel retainers)


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 99.4% 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.

 Motor 'cooling fan' repositioned for quieter operation

 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 tighter fitting reels, and no 'flange rub' by adding a layer of rubber under the original table mats

 Pinch roller reconditioned / re-surfaced.

 Mains AC cord replaced

 Power supply board tested to it's intended +25VDC. We had full voltage to the record amplifier and was able to adjust record amp to intended levels.

 New VU meter illumination lamp installed (#25-090) and both record indicator lamps test fine.

 Internal 'Line Level', '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.

  Plays and Records GREAT both channels


  Records GREAT @ 0dB / 1kHz on High Bias tape (Maxell UDXL) w/ L=~+1dB and R=~+2dB, however, there is an issue with, random 'low volume' 'artifacts' that appear on one channel during recording. We noticed it when recording 'zero' signal on blank tape, but it's there. I'm the only one here who noticed it, but during very quiet passages, you might notice it when recording.

 Speed checked once 'warmed up', to 98..91% accuracy. (Meaning a 'factory' 1kHz tape plays back at 1011Hz. (tech note: has Sony 60Hz / #0 motor pulley installed from factory)

 Internal cabinet braces re-worked / re-glued.

 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!

GREAT performing Sony TC-377 1/4" Open Reel to Reel stereo tape Record / Play deck and has all 3 consumer speeds! Good for reel sizes up to 7" in diameter. Great for burning your tapes to CD or Hard Drive or for making new tapes. Also great for having fun in your project recording studio.
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")

Sony TC-377 Features include:
   
- Triple speeds @ 7.5 ips / 19cms, 3 3/4ips / 9.5 cms and extra long 1 7/8 ips / 4.75 cms
- 3-Heads for instant monitoring of tape levels / record quality while recording
- Plays up to a 7" reel as well as 3" & 5" reels
- Playback / Recording of either stereo or mono tapes
- "F&F" Ferrite & Ferrite Heads (super hard heads to prevent un-even headwear and maintain a perfectly parallel gap for preserving top end in recordings)
- Separate L & R Signal Input level controls
- Separate L & R Microphone level controls
- Auto-Stop
- Dual analog VU meters for monitoring Playback and Record levels
- "Sound-On-Sound" capable w/ independent L & R record Source / Monitor engage switches
- Tape 'Echo' effect capable
- Built-in Tape Type selector for normal or "Low Noise / Extended Headroom" tapes
- Dual front mounted 1/4" mic input jacks
- 1/4" Stereo Headphone jack
- Mechanical Tape counter
- Variable Output level control located near I/O ports
(one of the most important features on a deck in our opinion. Allows you to match volume level of other sources, allows adjustment for 'best' pre-amp input to avoid distortion, allows you to change the volume of the deck if you have it located remotely from the pre-amp / receiver as I do, and many other applications)
- Lockable Pause "Inst-Stop" lever
- Mic Attenuator selector
- RCA inputs and outputs
- Spring loaded tape hub spindles (no need for rubber reel retainers)
- Can be mounted in cabinet for 'vertical' orientation (as currently installed) or inverted for 'horizontal' use.
- 3-Prong, Grounded AC cord

Again, following the above stated bench work / testing, our technician has 'Certified' this deck and it is an great performer sonically and mechanically primarily for 'PLAYBACK', noting the above mentioned issue with 'Recording' on one channel. 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 near new. 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. Measures 16.25" wide x 8.5" deep x 15.75" tall and weighs 24 lbs unpacked.
