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 50+ 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 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 TC-353D. 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 from ebay sellers 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"
{as another example, not long ago I had a guy call with a similar story, except he stated he was on his "NINTH" reel to reel from that popular on line auction site. I thought he was surely exaggerating and I asked, "you mean a couple or three" and he assured me it was "9!". Essentially same story as above. (sorry, but at this point I don't remember his name, nor which deck he purchased from us, but if I do, I'll post that info.)}
________________________________________________________________________

An email we recently received: "Jerry, Although it has been a several months since we spoke, I wanted to let you know how much I have enjoyed the R/R tape player (Sony TC-530) I purchased. I found that my 50-year-old tapes were indeed still in good condition, and I have spent many hours listening to the music that had once been only a memory of my early years. The joy it has brought me was worth every penny. I especially appreciate the time you spent speaking to me on the phone to ensure that this was indeed the right purchase for my needs. It was as if you had restored the machine just for me. Please accept my thanks for helping me recover memories I had feared were lost forever. Sincerely, David in West Virginia"

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.

Original observations / conditions:
"Surprisingly 'clean' inside and out. Once pushed up by hand, speed was at 775Hz (vs 1kHz), varied and gradually slowed as tape progressed over a few minutes. Playback and Recording had decently and surprisingly strong and even levels for a deck that was in 'as found' condition. Fast wind sluggish / iffy. Fast Wind reluctant to start depending on progress thru tape. Auto-Stop wire sticky. Very noisy 'Joint Roller'. Typically dirty & intermittent pots / controls."
 
 
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 of "varnished" lubes, re-lubed and reassembled. Again, the entire transport assembly was painstakingly disassembled, cleaned and re-lubed as well as the always at issue, 'Pinch Roller swing arm' 'plunge' assembly
 
 
New 'Main Drive' belt replaced for trouble-free service.
 
 
All three internal drive tires / wheels removed, reconditioned on drill press and solvent cleaned for positive grip
 
 
Capstan / flywheel removed, cleaned and burnished. Axle / bushing cleaned and re-lubed. New E-Clip installed for flywheel retainer.
 
 
Both Supply and Take-Up reel hubs / clutches removed, disassembled, cleaned and adjusted. Bearing / bushing surfaces re-lubed. Clutch surfaces re-textured
 
 
 All hub brake pads have been resurfaced and re-glued.
 
 
 Motor re-lubed at both front and rear ports
 
 
 Internal power supply adjusted to proper +25VDC. Checked for 'ripple' with Oscilloscope .

 
 New fiberglass tape on RF shields
 
 
 All Internal & External pots, controls, & switches (including the linear 'record' switches) cleaned and tested for noise-free function ("Tape / Source" cleaned multiple times).
 
 
 Both spindles in perfect alignment.
 
 
 We also checked the reel table heights for no "reel rub".
 
 
 Pinch roller reconditioned / re-surfaced.

  Re-Sprung Re-wind mechanism arms
 
 
 Auto-Stop wire disassembled, cleaned and new 500,000 silicone installed. Mechanism tested for proper 'drop' time and stopping time once remainder of deck restored.
 
 
 VU meter illumination and 'Record Indicator" lamps tested as working fine.
 
 
 Internal 'Bias', 'Record-Level' and 'Play Back Level' micro-pot levels adjusted (bottom side of lower circuit board).

 
 Both linear record switches cleaned.
 
 
 Heads were cleaned and de-magnetized as well as the entire transport.
 
 
 Tape pressure pad mechanism adjusted properly for 'just enough' tension on all heads.
 
 
 Head alignment / azimuth has been checked for peak performance with 10kHz factory test tone / alignment tapes and oscilloscope on both Playback and Recording.
 
 
 Both level meters adjusted for even playback level w/ 700Hz STL factory test tone tape.
 
 
 Floor noise tested to >54dB w/ fresh, blank tape on PB.
 
 
 Plays and Records GREAT w/ 0dB / 1kHz in = +5dB / 1kHz out on Ampex 456GM tape, AND, in 'real world' testing, we found that it actually performed great on standard, Scotch "150" tape (also allowed 0dB on both Pink Noise & 1Khz). DDD 'Real World' CD recording sounded GREAT with very little high frequency loss! Deck actually sounds awesome and is probably in the top couple dozen, best sounding tape decks we've finished over the past couple decades.
 

 
 Speed checked to 97.7% accuracy (meaning that a 1kHz test tape PB @ 1024Hz / +102.4%).
 
 
 During 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
18+ hours).
 Cosmetically in great condition!

 GREAT performing Sony TC-355 1/4" Open Reel stereo tape deck with 3-Speeds! Great for all-around Playback and recording of reels up to 7" in diameter. Also has all three consumer reel speeds as you will see listed below. Great for burning your tapes to CD or Hard Drive or for a 'media transfer business'.

A couple of other interesting features of this particular deck over many other R2Rs.

- It allows for Sound-On-Sound
- Also the hub brakes are completely released when its Paused Play mode. This means that you can manually manipulate the reels back and forth by hand for the scratch effect DJs get with direct drive turntables.
- The above brake release design also makes this deck conducive for making Tape Loops
- Finally, as its not only a 3-Head deck, but also 3-speeds (1 7/8ips which is slower than many R2R decks) it can also be used with a mixer as a Tape Delay for guitar, Vocals and other instruments and since it has the slower speed as well makes it much more versatile as a Tape Delay.

 
 SONY TC-355 Features include:
    
 
 
- Triple speeds at 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
 - 5*" / 7" Reel Capacity (*compatible with standard 4-Track / 2-Channel tape format)
 - 4-Track / 2-Channel Stereo operation, or 4-Track / 4-Channel 'MONO' operation (meaning it will also play tapes recorded in the early 1960's!)
 - Separate L & R input level controls
 - Auto-Stop
 - Dual analog VU meters for monitoring Playback and Record levels
 - "Sound-On-Sound" capable w/ independent L & R record engage switches
 - Built-in Sony "Noise Suppression" circuit
 - Dual front mounted 1/8" mic input jacks
 - 1/4" Stereo Headphone jack
 - Mechanical Tape counter
 - Pause "Inst-Stop" lever
 - RCA and DIN inputs and outputs

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

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

 AC mains selector and fuses checked and corrected as necessary

 Internal fuses checked for continuity and correct values. No issues found, fortunately. We don't like seeing incorrect fuses having been installed in a unit as that could mean it had prior issues, or if a fuse value was 'increased' it could have allowed too much current through an 'ailing' circuit causing un-due / un-necessary damage.

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

 Entire transport was cleaned and re-lubed

 Entire transport and tape path de-magnetized

All tape path rollers cleaned

Pinch Roller 'lathe' re-surfaced, cleaned and re-conditioned w/ our shop standard, MG Chemicals Rubber Re-conditioner.

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

 Brand new and CORRECT, #FR13.4 main drive belt installed

 Both reel table belts reconditioned

 Braking adjusted on fast wind modes also.

 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 tapes

 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.

 Both internal speed pots adjusted to 99.9% accuracy (1000Hz=1001Hz) (with pitch control zero'd) (meaning that our 'verified' 1000Hz test tape now plays back at 1001Hz +/-1Hz).

(Tech note: >>All dB references in service manual are in dBV which requires our Fluke 8060A to be set to dBV...)

 Playback / Record Head alignment / azimuth was already 'spot on', but we still did all of our checks for peak performance (max levels) with factory test tone tape and oscilloscope before electrical adjustments.

 We adjusted all eight VU meters w/ factory test tone tapes, as well as the internal playback and record levels.

 Deck has been fully calibrated to factory manual specs adjusting PB levels, Meter adjustments, Bias / Frequency adjustments (VC1& VC2), and internal record levels, tested, with Nortronics, Panasonic, Sony, Soundcraft, STL, TEAC and BRL alignment / test tapes (see resulting record level listed below). Biased best for Ampex GM456 / ATR Reference tape and records on Maxell UD also very well.



 Record bias adjusted for Ampex 456 or ATR Magnetics Master Tape

 Bias traps adjusted proper levels per service manual

 Following the above work and calibration, Recording tests performed with Ampex GM 456 / ATR MASTER Tapes (using output to adjust PB typically from .775 to 1V).
Heres the results;
Ampex GM 456 @ 15ips. w/ 1kHz @ 0dB = 0 to -2dB 1-8

 Floor noise measured at -66dB following above procedures

 This Fostex Model-80 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 15 hours).

Face is made of beautiful Black anodized, brushed aluminum and case is in great condition. Deck looks NEW and NOW works great! 

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.

The deck tests great! Looks and sounds great too! Only issue remaining seems to be that 2-3 segments of the LED meters will randomly not light (it depends on what mode the deck is being used in at the time). The segments that are out in this photo, are sometimes lit, with other segments that might be out instead at that time.
We couldn't really determine a pattern about the symptom, and decided it wasn't worth expensive tech time to trace it down, only to ultimately add to it's final price. Cosmetically it looks fabulous with just some minor scuffing on the display plexi you can see if the angle of the light is just right (see photos above). As most multi-tracks, including this one, do not have 'on-board' input / output level controls, it should be used with a mixer or similar outboard gear. We have completely gone through it. Will play  7"reels.

Fostex Model-80 Features include:


- 3 Heads for instant monitoring of tape levels while recording
- Single, 15ips Tape Speed
- 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)
- Dolby-C noise reduction (global defeat switch on rear panel)
- LSI Full-Logic tape transport for "Touch" control
- De-featable 10% Pitch control
- Electronically Assisted brakes for much easier handling of tape (reduces or eliminates tape stretch and / or breakage)
- Digital tape counter for "real time" or inches and also with 2 Memory points
- Dual Multi-Pin accessory ports on rear panel for time code / synchronization such as SMPTE or for Remote functions with remotes such as the Fostex 8031 or possibly the Fostex 8030 or 8316 (remote not included)
- Dual 1/4" remote ports on rear panel (remote(s) not included) one being for Punch IN/OUT using a Fostex 8051
- 8 Individual, 12-Segment Track LED VU level meters


Fostex Model-80 Specs from the owners manual as follows:

Head / Head-stack Format: 8-Track / 8-Channel
Motors: 1x Capstan Motor &  Reel Motors
Tape Speed:
15ips
Pitch Control: +/- 10%
Wow and Flutter: 0.06% Peak
Frequency Response: 40-18,000 Hz, +- 3 dB @ 15 ips
S/N ratio: 72dB weighted & 60dB un-weighted for 15ips @ +10dB @ 1k

Record Level Calibration: 0dB referenced to 320 nWb/m level of tape flux
THD: <1% @ 1kHz & 185 nWb/m level (we try and use tape capable of a way better "nWb/m" level, such as Ampex GM 456 or ATR)

Erasure
: >70dB @ 1kHz
Fast Wind Time: ~ 130 secs. for 1800'
Input level (line): -10dBV (0.3V) @ 30k Ohms, unbalanced
Output level (line): -10dBV (0.3V) @ 10k Ohms, unbalanced

As stated earlier we have spent 15 hours completely going through it cleaning heads and all else, lubing, adjusting, reconditioning pinch roller and / or replacing other rubber parts, demagnetizing heads and entire transport and testing everything. Tape speed has been 'internally' adjusted to 100% accuracy using a 1000 Hz test tape for the pitch control in it's 'centered' position. Plays and records 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, black anodized, brushed Aluminum and looks very nice. Very clean and looks near new. Unit looks GREAT! 

Great deck for revisiting your old, multi-track tapes, or if you have a media transfer business and need to transfer 8-Track / Multi-track tapes to a digital format. Certainly also great if you want to set up an actual 'analog' multi-track studio to record new music on.


Measures 14" wide (standard 14" 'Rack width' wide with optional rack ears installed) x 13.5" tall x 6.75" (from tip of back feet-tip of hubs) deep and weighs 29 lbs unpacked. Comes with an 'e-copy' / pdf download of the Fostex Model-80 owners / operations / users manual and service manual if purchaser desires. Also comes with a pair of the thread-on, OEM, Fostex reel locks / clamps. Includes our standard 30 day limited warranty.

A few 'multi-tracks', 'half-tracks' and 'semi-pro' reel to reel decks.
Clockwise, starting at upper left; TEAC A-2340SX, TEAC 40-4, TEAC A-2340R, TEAC 32-2B

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...

 Our technician has gone through this unit.

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

Heads inspected for excessive wear (obviously we do this 'early on' as 'excessive' wear will usually negate any further restoration work).

 Capstan cleaned and burnished in drill press while removed

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

 Pinch-roller mechanism pressure adjusted

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

Fresh / New 'Main' / Capstan belt (#42-860).

 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

 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 individual board and burnished contacts on channel Circuit Boards and re-seated. Adjusted pin contacts for better connections, but are still having issues with channels coming and going intermittently. When we had the unit inverted with it's covers off, we were able to get all the channels to randomly play and record by manipulating the individual channel circuit boards. The scuttlebutt on the web is that this is due to *solder joint issues on the main board. We may try and address that in the future, but for now it's available *'As-Is'.

 All meter lamps working and running 'cool'

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

 Internal Speed tested to 100% accuracy following refurb (meaning that our 'verified' 1000Hz accuracy using a 1000 Hz STL test tape.  (test tape now plays back at 1000Hz +/-1Hz and 2000Hz @ 15ips).

 Floor noise measured at >-74dB 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.

  (Total time investment in refurb / testing 7.5 hours).

Mechanically, the deck tests great! Cosmetically it's also in great condition. Really not much cosmetically to talk about that the above photos don't show.

TASCAM 34 Features include:

- Multi-Track / 4-Track / 4-Channel Stereo / Mono head stack / tape format
- 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 via optional, 'momentary' foot switch
- 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, Sync 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.
- Analog VU level meter for each channel
- Fluorescent 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 from us)
- 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 100% accuracy using a 1000 Hz STL test tape. Pinch rollers and heads all in GREAT condition!!!

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 TASCAM 34 service manual. Measures  18.25" tall x 16.25" wide x 10.2" (from tip of back feet-tip of hubs) deep and weighs 44 lbs
unpacked. Due to channel intermittency issues*, being sold "As-Is". Again, mechanically the deck works great following the efforts our tech has expended on it. If time allows, we (I) may revisit the solder joints on the connectors / main board. The price will drastically increase following that work, assuming it pans out.
(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.)

WORLD AC POWER"
for sale


Original observations / conditions: "Clean. Powers up. Deck was actually functioning well for Playback, meters, FF and REW and braking. Sonically decent on playback. Record levels were muffled. Take-Up spindle tight on some reels"

While we havent done our standard, full 25-30 hour restoration on this unit, (due to its weight its beyond what my tech wants to handle on the bench to the extent we do with most 25-40lb units), we have done the high points and got it to an acceptable level for *Playback (*recording is muffled on R&L and we didnt pursue that).

 Internal relays all are functioning.

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

 Internal transport mechanisms cleaned of old grease & re-lubed, capstan burnished, heads have been cleaned and de-magnetized as well as the entire transport.

 Pinch Roller swing arm assembly working fine as well as the brake arms and tape tension arms.

 Impedance roller bearing silent and has great momentum once tape travel stopped

 Magnetic brakes checked / tested on fast wind modes also so it doesn't "dump tape" when stopped.

 Capstan motor re-lubed.

 Take-up Spindle filed to allow better fit for 'tight' reels

 All user potentiometers and controls cleaned and tested for noise-free function.

 Both spindles in perfect alignment and run true with little to no wobble.

 Tape Head azimuth adjusted with factory alignment tapes.

 Playback Preamplifier adjusted to correct 1.228V.

 PB frequency response measured VERY flat out to 10kHz.

 Both VU meters work great with even response.

 We also adjusted the reel table heights.

 Heads in great shape as well, with many years of performance left in them and head alignment / azimuth has been checked and adjusted for peak performance.

 Both level meters playback even.

 Speed checked to 99.6% accuracy (meaning that a 1000Hz tape plays back at 1004Hz)!

(Total time investment in refurb / testing ~ 7 hours. Pinch roller and heads all in GREAT condition!!! Entire deck including brushed face, bezels, knobs and Real Mahogany Wood Veneer case in excellent condition!
We have extensively played this deck following the semi-restore, going through about a dozen tapes (mainly because it was the deck that happened to be on our demo bench, so I used it to audition a stack of tapes). It worked flawlessly.

____________________________

Great, restored, AKAI GX-360 Stereo Reel to Reel tape deck. Will play stereo 1/4" tape 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" for playback, 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 and tests functional for playback use!
Great deck for re-visiting your reel to reel tapes, or transferring them to computer hard drive. We did not test, nor service the Comput-O-Matic recording function.

- Manual Reverse Play Direction Switches
- Built-in Amplifier and Speakers with volume and tone controls (also has RCA Line Outs for connection to your stereo system or computer)
- 3-Heads for instant monitoring of tape levels / record quality while recording (again, a moot point, as we didnt address the record issue)
- 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)
- X-Field Bias system (again, a moot point, as we didnt address the record issue)
- 7" reel capacity
- "Soft-Touch", Solenoid assist tape transport controls
- Both RCA & DIN I/Os

- Dual analog, lit VU level meters
- Auto transport stop
- "Comput-O-Matic" automatically adjusts for optimum recording levels using in internally located, servo operated potentiometer (if feature is engaged) (again, a moot point, as we didnt address the record issue, and we didnt service that aspect)
- "Reverse-O-Matic" features allows you to pre-set auto-reverse segments if you choose
- Magnetic Brakes with tape mil selector for fine tuning for optimum braking performance in fast wind modes
- Auto power "Shut-Off" feature (selectable On / Off)
- "Sound-On-Sound" capable (again, a moot point, as we didnt address the record issue)
- "Clean Heads" warning lamp

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

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

     *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.

Original observations / conditions:
"Clean. Powers up (but AC cord loose due to cracked phenolic board in jack). No capstan motion (drive belt melted). TU reel spindle has issues and looks to be non-original. PR arm mechanism impeded by typical stiff lube.
Following partial restoration procedures we further found; Record levels low relative to what they should be. Lot's of 'hash' noise in playback and recording. Rear, Right sine wave has flattened bottom (distortion) on oscilloscope.   Levels randomly incorrect for PB or REC or Metering. Supply side bearing noisy on fast wind. Skids broken.
"

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

 Internal fuses checked for continuity and correct values. No issues found, fortunately. We don't like seeing incorrect fuses having been installed in a unit as that could mean it had prior issues, or if a fuse value was 'increased' it could have allowed too much current through an 'ailing' circuit causing un-due / un-necessary damage.

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

 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.

 New AC input port installed as the original was cracked and not safe.

 One of the reel spindles had been 're-built' or changed / modified when this came in to us. It had DIY tridents on one table from another spindle that didn't quite fit and barely functioned. We noticed there was a 'hair-line' crack on the reel table spindle that was not solid enough. We replaced the entire spindle / reel table with an OEM (original Pioneer) part (taken from one of my personal decks). Now spindles run 'true' with no excess vibration / wobble, lock on to the reels properly and don't 'hang up' on the reel.

 The biggest issue with this deck as that pretty much all of the transistors on the Playback / EQ amp board, Record Amp board, and Bias boards had developed 'black leg' and was causing channels to intermittently cut out, and was causing noise and distortion in both recording and playback.    This was from the commonly problematic transistors (twenty-three in total); 2SA672, 2SC1213, & 2SC1344 as well as some electrolytic capacitors. Some of these took the effort of recording MANY tapes while monitoring to locate as being the issues, as well as extensive time with alternate heating and cooling of circuit boards with a heat gun and freeze spray. We then replaced with quality NTE replacements (not Chinese look-a-likes)    (this step took many hours to replace 25 or 30 transistors, and re-test / check every three transistors during the process).

 Playback and Record Amp circuit boards had their solder joints reflowed. (this step took a lot of time)
Following all of the above work, we recorded entire 7" / 1800 foot tapes, on all of the EQ / Bias switch combinations over multiple days (monitoring at one of the benches while tech worked on other projects, listening for random noise). After changing the above mentioned transistors and finally a couple problematic caps, the deck recorded and played clean on all EQ / Bias positions consistently for days.


 The original 'guide roller ball bearing' unit was being very noisy on fast wind (meant that it was worn out), so we sourced an NOS, Nachi built (most of what's available are cheap, Chinese made units, which we didn't want to use). It took a lot of leg work to find the correct bearing for this that wasn't just a cheap, look-a-like (the local supplier only had two left, and the rest were Chinese from now on, so I bought both of the good one's they had left).

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

 PR mechanism solenoid mounts adjusted

 'Shut-off' arm removed, disassembled, had bushing and axle cleaned and re-lubed.

 Tape Lifter arms rotated to 'like new' section / area

 Capstans / flywheels removed, bushings and axels cleaned and re-lubed w/ 80/90 wt.

 Capstans burnished

 Rubber pinch rollers have been cleaned and re-conditioned

 Brand new MAIN drive belt installed (#42-540)

 Brand new Counter belt installed (#046)

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

 Brakes adjusted on fast wind modes also (optimized for 10.5" reels, but works great for 7" as well*). .

 Back tension adjusted on both reel motors (optimized for 10.5" reels, but works great for 7" as well*).

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

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

 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.

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

 Speed measured @ 98.9% accurate (meaning that a 1000Hz tape plays back at 1011Hz.)

 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.

 Deck has been fully calibrated as close to factory manual specs as practical, tested, and found to perform well in all categories

 Internal Record levels adjusted with proper, factory alignment / test tapes

 Internal EQ levels adjusted with proper, factory alignment / test tapes



 Record Bias adjusted internally with Bias Level at 22.0VAC and Bias trap at <1.0VAC L&R, but then sonically optimized for Ampex GM 456 tape, Scotch 150 and Maxell XLII on the different positions for the 'User selectable' EQ and Bias selectors.

 Following the above work and calibration, Recording tests performed with Ampex GM 456 / ATR MASTER Tapes (using output to adjust PB typically from .775 to 1V).
Heres the results;
Ampex GM 456 @ 7.5ips. ANY EQ / Bias position, w/ 1kHz @ 0dB; L= 0dB L & R = 0dB
~ 0.3dB!!!
Bottom line is, this thing is a RECORDING MONSTER!


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

 Two OEM, 'skid' sourced and installed, as the originals had missing sections.

 This Pioneer RT-1020H 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 ~ 38 hours).

Face is made of brushed stainless steel, aluminum and 'real walnut wood veneer' case is in great condition with only minor dings, scuffs, smudges, with some 'whitish' staining around the transport control bezel as well (see photos above). Nothing too distracting. Deck looks, works and sounds great! 

This one is from my personal collection that I finally had my tech do before he 'rides off into the sunset). It's "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.

The deck tests great! Looks and sounds great too! We have completely gone through it. Will play 5", 7" & 10.5" reels (10.5" reels require optional NAB hub adaptors that we generally have available at their additional cost).
____________________________

Looks great & following above service, is "Ready-to-go"! The very sought after and rare, Pioneer RT-1020H Stereo Reel to Reel tape deck. Will play / record stereo 1/4" tapes on reels up to 10.5". This model is very unique for a couple reasons. One is that it will record and play at double, the standard 'consumer, 'High' speed', meaning that you can get top quality recordings from it. Also, as well as playing standard consumer 4-track / 2-channel tapes (as long as they're not the slow, 3.75ips speed), but also will play 4-channel "quadraphonic" tapes and ALSO 4-Track / 4-Channel "Pro-Multi-Track" tapes made from such decks as the Tascam 2340 or 3440! That means if you have some of those 'multi-track' tapes you need to transfer into a DAW, then here you 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 and all functions test great! Looks and sounds great too! We have completely gone through it. 

From the original brochure: "Stability, Strength from the 5mm thick chassis board and die-cast framework" (same frame construction method as the RT-909)
(This deck series was the predecessor to the Pioneer RT-909, and the main difference in construction is that the RT-901 / RT-909 uses a "DC" powered motor. While that does allow the RT-901 and RT-909 to have a Pitch Control, DC motors tend to have a much shorter lifespan {as in about 10-20% of an AC motor}. That is evidenced by the number of calls we get to our parts department for replacement RT-909 capstan motors {which are pretty much 'un-obtainium'}).
The Pioneer RT-1020H is much rarer than it's sibling, the RT-1020L. The two are almost exactly the same, except the two speeds that the "H" model does is 7.5 ips and 15 ips, which allows better quality recording (see the 'Frequency Response' specs below). Now as this deck does the higher 'consumer' speed of 7.5ips and the pro-speed of 15ips, it does not run at the lesser quality, consumer speed of 3.75 ips. If you're a consumer or media transfer house and need to utilize tapes that were recorded at 3.75 ips, you could play them at 7.5ips into a computer, then use standard audio software to slow it down to half speed. The quality would vary depending on many factors, primarily the quality of the computer / software you were using.


Pioneer RT-1020H Features include:

-  4-Track 2 or 4 Channel playback and 2-Channel recording
- 3 Heads for instant monitoring of tape levels while recording
- Handles up to 10.5" reels!
- 3 Motors for trouble free performance (has a lot to do with it still being a viable piece of gear due to fewer rubber parts)

Original observations / conditions:
"Clean. Powers up. No capstan motion (drive belt melted). Original owner stated that it had stopped recording sometime ago and now only played, but couldn't get it to run at all anymore. Tape lifter mechanism VERY stiff. Flat spots on tape guides. Pinch roller arm cushions / bumpers hardened / deteriorated. Counter / Memory LED's look 'odd'. PR arm mechanism impeded by stiff lube.
Following partial restoration procedures we further found; tape skews off PR in Rev PB. Record levels low relative to what they should be. Tape PB azimuth incorrect. Tape speed incorrect. Levels randomly incorrect for PB or REC or Metering.
"


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

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

 AC mains selector and fuses checked and corrected as necessary

 Internal fuses checked for continuity and correct values. No issues found, fortunately. We don't like seeing incorrect fuses having been installed in a unit as that could mean it had prior issues, or if a fuse value was 'increased' it could have allowed too much current through an 'ailing' circuit causing un-due / un-necessary damage.

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

Controls were 'flooded' w/ 'De-OxId' and are quiet

 Entire transport was cleaned and re-lubed

 Entire transport and tape path de-magnetized

Both capstan / flywheel assemblies removed, cleaned and re-lubed

New rubber PR arm cushions / bumpers installed

Both Rubber pinch rollers have been, lathe re-surfaced, cleaned and re-conditioned w/ our shop standard, MG Chemicals Rubber Re-conditioner.

Adjusted PR pressure / stroke

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

 Brand new and CORRECT, main drive belt sourced and installed (was not easy to deduce as most of the ones spec'd for this unit are NOT correct)

 Braking adjusted on fast wind modes also.

 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

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

 Repaired / re-attach counter and memory LED's

 Both spindles in perfect alignment (no bent / tweaked spindles or compromised tridents).

 We also adjusted the reel table heights.

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

 Both internal speed pots adjusted to 100% accuracy on either speed independently in forward / -> direction. Reverse / <- direction is accurate to 99.4% (1000Hz=1006Hz) (with pitch control zero'd) (meaning that our 'verified' 1000Hz test tape now plays back at 1000Hz).

>>The following operations took MANY hours (17-19hrs) to fine tune and complete, one because this is a complicated deck to get correct, AND two, it's capable of 'Bi-Directional' recording, so everything has to be duplicated for Reverse Recording...<<

 BOTH direction Playback and Record Head alignment / azimuth was adjusted for peak performance (max levels) with factory test tone tape and oscilloscope before electrical adjustments.

 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.

 Deck has been fully calibrated to factory manual specs adjusting PB levels, Meter adjustments, Bias / Frequency adjustments (VC1& VC2), and internal record levels, tested, with Nortronics, Panasonic, Sony, Soundcraft, STL, TEAC and BRL alignment / test tapes (see resulting record level listed below). Biased best for Ampex GM456 / ATR Reference tape and records on Maxell UD also very well.



 Record bias adjusted for both directions, both channels and both types of tapes

 Bias traps adjusted proper levels per service manual

 Following the above work and calibration, Recording tests performed with Ampex GM 456 / ATR MASTER Tapes (using output to adjust PB typically from .775 to 1V).
Heres the results;
Ampex GM 456 @ 7.5ips. Norm position, no NR, w/ 1kHz @ 0dB; L= +1dB L & R = 0dB


Ampex GM 456 @ 7.5ips. Norm position, w/ dbx, w/ 1kHz @ 0dB; L= +1.0dB L & R = +0.5dB

Ampex GM 456 @ 7.5ips. EE position, no NR, w/ 1kHz @ 0dB; L= +1.5dB L & R = +0.5dB

Ampex GM 456 @ 7.5ips. EE position, w/ dbx, w/ 1kHz @ 0dB; L= +2.5dB L & R = +0.5dB

Recorded DDD CD material averaged -4 to -5dB L&R when pushed EE, No NR and no output compensation.

 Floor noise measured at >-74dBu following above procedures

 This Teac X-2000RBK-EE 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 34+! hours).

Face is made of beautiful Black anodized, brushed aluminum and case is in great condition. Deck looks NEW and NOW works great! 

This is one of my personal favorites! The TEAC X-2000RBK 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.

This deck comes from a culmination of decades of experience by TEAC of building tape transports (they make the transport in the "little black boxes" on aircraft BTW), and one thing the TEAC X-2000R is known for is 'gentle tape handling'. From the original OM, "To maintain very stable tape motion with optimum tape tension, it uses a full tension, servo control system in which a photo-interrupter senses the position of the tension arm so that the servo mechanism can adjust the torque of the reel motor"...means that it virtually eliminates the likely-hood of tape stretch or breakage.

The deck tests great! Looks and sounds great too! We have completely gone through it. Will play 3", 5", 7" & 10.5" reels (10.5" reels require optional NAB hub adaptors that we generally have available at their additional cost).

TEAC X-2000RBK-EE Features include:

 - Super hard, 'Cobalt Amorphous' (CA) heads
- 6 Heads (3 for each direction) 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)
- EE (Extra Efficiency) recording capability
- dbx PROFESSIONAL noise reduction
- Tri-mode Auto-Reverse w/ Bi-Directional Recording (Auto-Reverse requires correct installation of 'Sensing' tape on your audio tapes)
- Dual Capstan Drive
- LSI Full-Logic tape transport for "Touch" control
- Dual Capstan / Closed Loop Tape transport
- De-featable 6% Pitch control
- Electronically Assisted brakes for much easier handling of tape (reduces or eliminates tape stretch and / or breakage)
- Dual front mounted 1/4" Microphone inputs
- Digital tape counter for "real time" or inches and also with Program and CUE, Repeat, "Rapid Search" functions, STC & STZ features 
- Timer Play
- Auto-Spacer for record mode
- 12-Pin optional wired remote port on rear panel (remote not included)
- 5-pin DIN "Dupli Sync" port on rear for "daisy chaining" units together
- Dual speeds at 7.5 ips / 19cms and 3 3/4ips / 9.5 cms
- Separate dual mic and line level controls
- Dual 1/4" front mounted mic inputs
- Source / Monitor selector
- Output level control
- Dual analog VU level meters

As stated earlier we have spent 34+ hours completely going 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 in both Hi and Lo speed positions have been 'internally' adjusted to 100% Fwd and 99.6% Rev accuracy using a 1000 Hz test tape for the pitch control in it's 'centered' position. 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, black anodized, brushed Aluminum and looks very nice. Very clean and looks near new. Unit looks GREAT!

Original observations / conditions:
"Actually runs fairly well, but NO brakes! Transport control paddles stiff and sluggish. Counter not working. Had playback sound fairly consistently from both L&R, unless head position selector manipulated. Recording too intermittent to draw any concise results. Typical 'deferred maintenance' like most 40 to 50 year old decks. Once face was removed, it was discovered that the brake pads had completely deteriorated and disappeared."

Our technician has EXTENSIVELY 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 removed / disassembled, cleaned, re-lubed with synthetic lube and reassembled.

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



 Even though this unit was built by Akai, it doesn't utilize all the 'deposited metal' cam dogs that all the other Akai's from the late 60's thru the upper-mid 70's use, with one exception. It uses one for the 'head position' selector and it does have some small hairlines in it (as most all Akai and Robert decks do). It does still function, but we are shipping this deck with the selector handle removed. You can still use it and it does still function fine, but it may fail at some point in the future. Moving the head position is such a 'little used' feature that we chose to remove the knob to avoid the possibility of someone moving it in the future to one of the 'mono' positions, then having it break and not be able to get it back to the 'stereo' position.

 Capstan removed (with motor), bushings and axel cleaned and re-lubed

 Capstan burnished

 Both spindle hubs disassembled and clutch discs inspected (in near new condition)



 Drive motor removed, partially disassembled, cleaned and re-lubed.

 Pinch roller removed, resurfaced / reconditioned on drill press, and had it's bushing lubed prior to re-install

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

 Brake pads sourced from three other donor machines (in order to get the correct combination of sizes required for this model), cleaned / reconditioned

 Brakes adjusted on fast wind modes so that hub clutches could function properly. YES, like all of our decks, it's been fully tested on both 7" and 10.5", completely loaded tapes from full speed all the way to 'dead stop' going both directions, at all points of tape progress for fast wind starting and braking.

 Utilizes and 'oil bath' start / run capacitors for the motors so no need to every worry about replacing them.



 This is a 'Direct Drive' deck so no 'Main' drive / capstan belt' needed

 Brand new, #050 'Tape Counter' belt installed

 All transport functions now 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.

 Both spindles in perfect alignment, with minimal wobble / run-out and no missing fins

 We also adjusted the reel table heights.

 Meter lamps good (as they're very 'cool running')

 Heads cleaned and de-magnetized (as well as entire transport) and are in great shape as well, with many years of performance left in them.

 Mic / Line / Tone control pots cleaned for static free performance

 Deck has been calibrated as close to factory manual specs as you can on a 60 y.o. deck, adjusting PB levels, Meter adjustments for PLAYBACK ONLY.

 Speed tested to 99.6% accuracy @ 7.5ips (1kHz = 996kHz)

VERY, VERY Fast wind tests as follows w/ 1800' tape: REW= ~55 sec

 Flutter tests produced no audible issues.

 We spent extensive time with the erase head / record head voltage oscillator board. We replaced or tested every component on it and even though we were getting the correct voltages at the correct frequencies, we could not get it to erase tapes, then it failed recording on blank tape, thus it's being offered as a Playback Only deck.

 This Roberts 5000X plays very well. Great deck for archiving your existing tapes to another format.  (Total time investment in refurb / testing ~ 31+ hours).
____________________________

Looks GREAT & is "Ready-to-go"! Will play / record stereo 1/4" tapes on reels 2.5", 5" & 7" (brakes optimized for 7" reels). 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  as a playback tape deck.
***So following it's initial restoration, we discovered an issue with 'erase' function. We spent a lot of time on it trying to deduce why it wasn't erasing. It would record VERY well with blank or bulk erased tape, but would not erase. In the process of troubleshooting the erase / bias circuit board we replaced a couple transistors with subs, which once assembled, not only did not address the lack of erase function, but then caused issues with record quality. At that point we decided to make it a 'Playback only' deck as that erase work had put us to double the time we had in the balance of it's restoration.
Deck does come in carrying case with latch-on lid.

Built-in amp and speakers make this a "stand alone" unit, yet can still be connected to your stereo system.  

A few other notes of interest regarding this deck;
It utilizes a 'direct drive' capstan, thus no belt to worry about. Also, the capstan motor (actually and "Akai Syncom" motor) is ginormous, relative to most others.



Lot's of torque. Thirdly, the motor is AC powered so way longer lasting than DC motors (as in about 10 times longer life). Also, the start / run capacitors in this unit are 'oil can' types, so should never wear out or get 'old' like most "Start / Run" capacitors.



Also, the 'built-in' amp and speakers actually sound pretty good. Having speakers built-in may have made your 'short list' of features to have on a reel to reel, but they're actually VERY handy once you use them.


Roberts 5000X Features include:

- 4-Track / 2-Channel or Mono-1 Channel Recording and Playback
- 3-Heads for instant monitoring of recording (***again, a bit of a moot point, as it's only being offered as a "Play" deck)
- Built-in stereo amp and dual 4x6 speakers
- 3 Motors
- Direct Drive Capstan

- Dual Speed transport, supporting 3 3/4 ips and 7 1/2 ips (no speed sleeve required)
- Dual front mounted " Microphone inputs
- Analog Tape Counter
- Tape EQ selector for 3.75ips and 7.5ips
- Variable Output / Volume controls
- Tape-Track / Stereo selector
- Dual Mic / Line level controls
- Dual, lighted analog VU level meters
- Front mounted Stereo Headphone Jack
- Side-mounted 1/4" Phono jacks for input and output (comes with a 4-pack of gold finished 1/4" to RCA adaptor plugs)
- Bass Boost (Loudness) switch located on the side for internal amplifier

 - Dual " External 8 Ohm speaker outputs
- Auto stop for play and fast wind functions

As stated earlier we have completely gone through it cleaning, lubing, adjusting, demagnetizing and testing everything.
Deck also in good cosmetic condition. About the only issues worth mentioning is some finish chipping on the tape counter and a few scuffs around the 'Head position' selector knob. Also a couple of the plastic feet from the back panel cracked / broken so we removed all four of them (see above photos).
If you want to simply listen to your existing tapes, have a media transfer business, and / or need a deck to fast wind tapes VERY fast, then here you go.
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.

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

Original tech notes on 'pre-inspection';
"Fairly clean, and does have some normal function...main drive tire dried & cracked and will need to be replaced...dents in pinch roller...FF & REW partially function. Heads have nominal wear. Entire transport needs total overhaul...motor is quiet...main drive belt may be recent replacement...Right channel very low output and sometimes 'motor-boating' on PB...Left channel 'muffled'  due to pressure pad issues. Left meter ''mechanically' stuck. PB. speed; unable to determine as entire transport doesn't function well enough...Brakes not great. VERY noisy controls...leaf switches intermittent to non-functional...Rec pressure pad too flat...very little high frequency likely due to pressure pad issues (the pressure pad issue ended up being an inordinately difficult and time consuming issue to resolve)."

 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.

 Capstan 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.

 New Main AC / Line / Power cord included

 Burnished leaf switches

 VU meters replaced with meters and lens from two other TC-530 donor units to get one good set

 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.

 All idler tires milled and 'reconditioned'

 Main Drive reconditioned and counter belt (#044) replaced for trouble-free service.

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

 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.

 Pressure pad fabricated and positioned correctly (this alone took about 6 hours and is VERY critical on these Sony decks for good playback and recording freq response)

 Records well, but much lower on VU than input (about -12-15 dB). Sonically fine. Biased for Scotch 150 (very common to acquire) tape with the following results:
1kHz recorded @ 0dB resulted in PB @ -15dB (with minimal 'artifacts')

'Real World', DDD CD recorded at 0 = -12dB, however sounded actually quite nice. While this deck is a much better 'playback' unit than a 'record' unit, it actually makes quite passable and listenable recordings. If you didn't monitor the meters, you wouldn't know any difference
* We also had great results with Scotch 203 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 -54dBm 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 99.98% accuracy utilizing 'factory' test tapes meaning that 1000 Hz tape plays back at 1002Hz +/-1Hz!

 FF / REW and braking from top speed all good throughout the length of tape travel

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

(Total time investment in refurb / testing 20.5 hours).
Deck is now in overall, GREAT condition!!!

(speed is correct to 100% @ 1kHz) and making test recordings. All fast wind and stop functions work perfectly at any point in the tape. Cosmetically overall in great condition. 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.

Original observations / conditions:
"Bent TU spindle. Sluggish on all transport functions, esp play either direction. Recording very intermittent on forward or reverse (found multiple switches related to head movement needed cleaning) (also found an additional 'reverse recording' switch while restoring / testing that needed further service). When it did record, it was on average -5-8dB. Left VU meter physically binding at times. Brakes 'iffy'. Counter not moving once transport gets going. Missing rear cabinet feet. Auto-Reverse intermittent (mostly not working correctly. Found to be 'idler wheel'). Pinch roller had excessive ("excessive" for our standards) 'flutter' even after typical reconditioning multiple times (eventually sourced a new one from Italy which solved the issue). Once initial restoration completed we found that the brakes were not sufficient at a couple spots in tape progress during fast forward to not 'dump tape' when loaded with our heaviest, dual metal reels. In doing that operation, we discovered that one of the input level pots had developed a 'bad feel' when rotated, and that the meter mounting pin cushions had deteriorated.

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

 Internal fuses checked for continuity and correct values. No issues found, fortunately. We don't like seeing incorrect fuses having been installed in a unit as that could mean it had prior issues, or if a fuse value was 'increased' it could have allowed too much current through an 'ailing' circuit causing un-due / un-necessary damage. We also verified that the voltage selector was set to correct, 120VAC.

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

 Most transport subassemblies were disassembled down to the chassis, cleaned, re-lubed and reassembled. 

 


 'Pinch Roller swing arm' assembly disassembled, cleaned and lubed

 Both spindle hubs disassembled, and spindles straightened

 Capstan Drive motor (Sony UC-214G) inspected, cleaned and lubed   

 Reel Drive motors (Sony UC-624G) inspected, cleaned and lubed

 Knurled drive pulley cleaned of old rubber residue

 FRESH, NEW Pinch roller sourced from Europe, then pre-conditioned, and lubed prior to re-install (after trying your standard reconditioning on the original pinch roller, and repeating a couple more times, we still weren't happy with the performance, so we ordered the new one)

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

 Also brake hubs have been cleaned & re-lubed

 New brake pads installed and adjusted on fast wind modes also.

 Brakes adjusted on fast wind modes also.

 Back tension adjusted on both reel tables.

 Brand new, #034 & #040 'Tape Counter' belts installed

 Internal felts re-secured as their old epoxy was failing

 Take-Up hub brakes had extra spring added to compensate for fatigued original and brakes adjusted to work with dual metal reels

 'Tape Counter' cleaned & lubed to eliminate typical 'counter rattle' noise.

 VU meters disassembled, locate pins and aluminum scales re-secured, covers re-installed and new pin cushions fab'd and installed.  



 All transport functions now 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.

 Right Input level pot replaced with a sourced, OEM unit due to deteriorated internal plastic   

 Rear OEM feet / bumpers sourced from another Sony and installed

 Both spindles in perfect alignment, with minimal wobble and no missing fins

 We also adjusted the reel table heights.

 'Direction Change Stopper' wheel, resurfaced / rebuilt for correct tension arm operation as well as other internal tires replaced or reconditioned.



 Heads cleaned and de-magnetized (as well as entire transport) and are in great shape as well, with many years of performance left in them.

 Mic / Line control pots cleaned for static free performance

 Deck has been fully calibrated to factory manual specs adjusting PB levels, Meter adjustments, Bias / Frequency adjustments and internal record levels, tested, with Nortronics, Panasonic, Sony, Soundcraft, STL, TEAC and BRL alignment / test tapes (see resulting record level listed below). Biased best for Ampex GM456 / ATR Reference tape and records on Maxell UD also very well. Tested on all tape types recording at -0dB (most manufactures test at -20dB). You won't always want to record at 0dB, but generally somewhere between -10 up to -3 works best with most decks.

 Tape head azimuth adjusted out to 15k for record and playback heads.




 Speed tested to 100% accuracy (1kHz = 1.000kHz +/- 1Hz!) (That's pretty awesome speed accuracy BTW)

 Floor noise measured at >-60dB following above procedures

 Following the above work and calibration, Recording tests performed with Ampex GM456 (again, same formulation as new ATR tape), Maxell UD (Gold / Black), Scotch 203 and Scotch 150 Tapes.
Heres the results;
Ampex 456 @ 7.5ips. 1kHz @ 0dB = L= -2dB L & R =+0.5dB
Forward
Ampex 456
@ 7.5ips. 1kHz @ 0dB = L= -1dB L & R = 0dB Reverse
Maxell UDXL @ 7.5ips. 1kHz @ 0dB = L= -3dB L & R = -1.5dB
Forward
Maxell UDXL @ 7.5ips. 1kHz @ 0dB = L= -3dB L & R = -2dB Reverse
Scotch 203 @ 7.5ips. 1kHz @ 0dB = L= -7dB L & R = -1.5dB
Forward
Scotch 203 @ 7.5ips. 1kHz @ 0dB = L= -6dB L & R = -6dB
Reverse
Scotch 150 @ 7.5ips. 1kHz @ 0dB = L= -3dB L & R = -4dB
Forward
Scotch 150 @ 7.5ips. 1kHz @ 0dB = L= -1dB L & R = -7dB Reverse

Ok, that's how "1k" sounded, but how about MUSIC?
Ampex GM456 with Recorded program from "ddd" source extensively. Forward recording is very good quality. Reverse was Exceptional! Overall, with quality tape, the and deck sounds fantastic!

 This SONY TC-730 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 ~ 58++!!! hours. OUCH!!!).

 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 EXTENSIVE restoration with the above mentioned 60'ish hours of tech time. It's pretty much had the clock rolled back 40 years on it. Restored, extensively tested / played, then re-benched after 'burn-in' to double check performance / adjustments. The only comment I would make regarding mechanical performance, is that the dual, recording switch paddles / buttons can be a bit 'fiddly' to engage or disengage sometimes. It helps to make sure that there is no slack in the tape (which is pretty much the case with all decks, but this deck requires zero slack, or the auto stop will engage). There's a bit of extra "hiss" and mild 60Hz "hum" from the internal amp, but we didn't pursue that too far as we realize that most folks will connect this to a stereo / sound system / computer, and those extra sounds are not present at the Line-Out jacks. Cosmetically there's a few minor battle scars and missing toggle tips previously mentioned, but nothing significant (see photos above).
 Looks great & Ready to go! Comes with a take-up reel. Again, GREAT for burning your tapes to CD or Hard Drive or for a 'media transfer business'. Also handy for archiving / researching / revisiting your tapes without having to have a system nearby as it has a built-in amp and speakers. The built-in amp and speakers actually sound great with separate bass and treble controls. The amp has ample power to driver external speakers as well pretty decently. We had a blast doing our final testing with this unit as it's actually 'FUN' to use. Can include a pdf 'e' copy of the Sony TC-730 Owners manual (very poor copy) and a copy of the Sony TC-730 service manual if the purchaser wishes. Includes our standard 30 Day limited warranty. Measures 21" wide x 9" deep x 19.5" tall and weighs 51 lbs unpacked.

On a side note: While we deal in many Open Reel / 'Reel to Reel' Tape machines, have recently seen folks making references to 'Real to Real' & 'Reel to Real' tape recorders / decks...
We think this might be referring to some sort of 'cloning machine' or 'replicator' such as shown aboard Star Treks' Enterprise ship in the 'Next Generation' and 'Voyager' series.
...Just throw'in it out there.
