ü Our technician has completely and EXTENSIVELY gone through and 'Certified' this unit which involves complete disassembly of the transport (not an easy task on this table), cleaning inside and out, COMPLETELY DISASSEMBLING, cleaning and re-lubricating all internal mechanisms and the balance of efforts listed below.


ü Heads inspected for excessive wear (obviously we do this 'early on' as 'excessive' wear will usually negate any further restoration work, although as these are 'GX' heads, it would be pretty hard to put much 'wear' on them). These have virtually NO visible wear to them.

ü Internal DC power supply tested

ü Capstan motor disassembled, cleaned and re-lubed.

ü Both Flywheel 'belt surfaces' solvent cleaned

ü Bronze Flywheel bushings solvent cleaned

ü Both Flywheel thrust pads cleaned

ü Capstan burnished

ü 'Reel drive' tires (7 IN ALL!!!) reconditioned for trouble-free service. (These are actually much more important to replace on this deck (and most) than the belts. Without these, the deck won't fast wind very well, and will likely 'eat tapes' as the 'take-up' reel won't turn properly)

ü New internal Capstan Drive belt (#FRM9.2) installed for trouble-free service. (so this operation required extensive effort. The belts that came in the so called "correct kit" currently available for the Akai GXC-730D, proved to cause incorrect speed in two different decks. We were then forced to find new belts that by 'trial and error' allowed enough 'traction' and the most speed accuracy. In fact, none of the belts in the 'official kit' that is currently available for an Akai GXC-730D allowed the deck to operate at anything resembling correct speed when tested on a frequency counter with factory test tapes!)

ü New 'Counter' belt (#.041) installed as well as 'spindle' belt #029.

ü 'Non-locking' 'Pause' control disassembled, cleaned and re-lubed

ü Rubber pinch rollers have been reconditioned

ü Tape well door 'eject' springs re-worked / repaired

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

ü Head alignments and azimuth checked and adjusted as necessary for 'peak performance' with O-Scope

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

ü Both d'arsonoval VU meters 'static adjusted', tested and working fine.

ü Both VU meter illumination lamps replaced.

ü Both hub spindles in perfect alignment.

ü FF, REW, & Play transport functions all test perfectly and controls tested for 'positive / accurate' responsive.

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

ü Replaced 'Erase Head', reed switch with OEM from another of the same model (very difficult to deduce and locate as source of issue with deck 'not erasing' correctly)

ü Playback meters zero adjusted 'electronically' with factory test tone tape.

ü Tape Counter Function tested

ü Plays perfectly and records well with 1kHz, recorded 0dB playing back @ L=-2dB & R=-3.5dB (between TDK and Maxell tapes). With DDD CD we experienced ~ -5 to -6dB, but great, overall sonics! (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).

ü Pinch roller and heads all in GREAT condition!!!

ü Floor noise tested to -60dBm with empty shell tape

ü Speed tested to 98% accuracy with 1kHz factory test tape (meaning 1kHz calibration tape plays back at 980Hz +/- 1Hz)

Only issue still remaining is that "Rewind" is noisy on some tapes as it nears completion.

ü Deck has had just over 18.5 hours of restoration work done.

Face is made of beautiful brushed aluminum, and overall the deck is in NEW cosmetic condition. Following the extensive restoration, we did 'test recordings' of a 'ddd' CD on 6 tapes; Sony Normal Bias, Fuji Normal Bias, TDK Normal Bias, Maxell Normal Bias, TDK 'SA' High Bias, and Maxell 'XL-II' High Bias. We found that for Normal and High Bias, of those tapes tested, both the "Maxells" performed VERY well on this particular deck.
Total technician time to restore ~18.5 HOURS!

Handsomely designed, and classic looking Akai GXC-730D, Auto-Reverse cassette tape deck. Features Piano-Key transport, Auto-Reverse, & Dolby B. Great deck for most systems and uses. One of the 'Biggest' cassette decks ever made.

AKAI GCX-730D Features include:
  

- 3-Mode Auto-Reverse ('Manual' reverse as well of course)
- Huge drive Motor
- Classic 'Piano Key' transport w/ Solenoid assist results in 'Soft Touch operation
- Dolby noise reduction built-in for recording and playback
- Akai's A.D.R. (automatic distortion reduction) changes the recording equalizer characteristics according to the signal level of a certain frequency band to achieve low distortion over an extended frequency range.
- Auto-Limiter (if selected) to limit 'over / peaks' on 'high energy' recordings. Great when recording in 'Live' situations.
- Tape Type selector for Normal, Fe-CO2, & CrO2 tape
- Dual, Large "VU" signal level meters
-
"Peak" LED level indicator that kicks in at +7dB
- Manual Record Level with independent L&R control
- Variable Output Level 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 front mounted 1/4" mic input jacks
- Front mounted Stereo Headphone jack
- Analog Tape Counter w/ "Memory Stop"

-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.


AKAI GCX-730D Specifications:

Track format: 
4 track / 2 channel
Heads: One "GX" recording / playback head and two Erase heads. 4 track / 2 channel
Motors: 
HUGE AC, High Torque, 4-Pole Hysteresis / AC synchronous
Freq Response: w/ FeCr tape; 35-17,000 Hz +/- 3dB @ -20dB

w/ CrO2 tape; 35-16,000 Hz +/- 3dB @ -20dB
w/ Normal / LN tape; 35-14,000 Hz +/- 3dB @ -20dB
Wow & Flutter (WRMS) - 0.080% WRMS
 S/N ratio: >50dB @ +3 on VU meter w/ LN tape. Dolby B NR adds ~10dB above 5kHz
Harmonic Distortion:  <1.5% @ 0dB w/ "LN" tape
Bias Frequency
100kHz
Erase Ratio
>70dB
Fast Wind time: <70sec* on C-60 Tapes (again, does have the above mentioned 'slowing' characteristic near the 'end' of FF operation)

There's just something about the feel of 'original piano key' tape transports. This one especially has a great "feel" to it. Like you're engaging some 'huge' mechanism internally. The 'Auto-Reverse' is very 'precise' in it's motion.
Again, we have completely refurbished and thoroughly tested this deck, with multiple recording tests (as stated previously). Cosmetically, it's in essentially NEW condition! Also great for transferring your tape collection to CD, Hard-drive or MP3. Includes original box and packing. Comes with an 'e-copy' / pdf download of the Akai GXC-730D owners manual and color brochure.
Measures 17.3" wide x 11.9" deep x 6.9" tall and weighs 26.5 lbs unpacked. Comes with our 90 day limited warranty.

The Teac CX-650R, Auto-Reverse with 'Bi-Directional Recording', Stereo Cassette Tape Deck. Great deck for doing your tape transfers if your tapes were recorded with no NR or with "Dolby B" or for making some awesome 'new' recordings or 'mix tapes' (hey, it's 'the thing' again). This deck is a pleasure to use, and has a great 'feel' due to it's size and transport function. As far as cosmetics, it's BEAUTIFUL. Was taken very good care of before it came to us, and is even more astounding now. The deck and the wood grain case could convince you that time had rolled back almost 40 years, and you were seeing it at the original store's retail display.

Teac CX-650R Features include:
  

- Heavy duty transport featuring 'oversized' capstan motor, and VERY large, 'asymmetrical' flywheels
- Triple-Mode Auto-Reverse, with 'Bi-Directional' Recording (not just 'A' side recording!)
-  "Soft touch-control" tape transport
- Selector for Normal (EX / I), CrO2 (SX / II) & Metal (ZX / IV) Tape Type
- 3-Position Selector for Tape Equalization for Normal (EX / I), CrO2 (SX / II) & Metal (ZX / IV) Tape Type on playback
- Dual Analog VU Level Meters
- Analog counter 
- Built-in MPX filter for killing the 19kHz pilot tone in FM transmissions
- Variable Output Level control (one of the most important features on a deck in our opinion)
- Dolby B NR
- Record Muting
- 'Auto-Space' records a 4-second space prior to 'stop' when engaged.
- Real 'Potentiometer' Record level controls that are 'gear coupled' (meaning when you turn one, the other one responds as well. They can be turned independently for 'fine adjustment' as they're 'clutch coupled' as well)
- Memory Stop / Repeat for counter
- Dual, Front mounted, 1/4", Microphone Jacks
- Front mounted, 1/4", Stereo Headphone jack
- Timer Play / Record function.
- Multi-pin port on rear panel for optional wired remote, TEAC RC-100 (remote not included)

Again, we have completely cleaned, refurbished / serviced and thoroughly tested this Teac CX-650R cassette tape deck.
Great for transferring your no NR or Dolby B NR encoded tape collection to CD, Hard-drive or MP3 especially with the 'Tape EQ' selector for 'fine tuning' older tapes. Built very well! Looks near new, works great and sounds fabulous. Due to it's size, overall feel, the 'input controls' and the 'transport control' this deck really is a blast to use. Comes with an 'e-copy / pdf download' of the TEAC CX-650R cassette tape deck owners / users / instruction manual. Measures 18.5" wide x 13.5" deep x 7" tall and weighs a VERY HEAVY 26 lbs unpacked. Just in case you 'too casually' read past that last little bit,
IT'S A TWENTY-SIX POUND CASSETTE DECK!

CASSETTE TAPES TAPE

We just bought a very limited quantity of these "mini-reel to reel" cassette tapes. Follow this link to order...Click Here 
 

 



Did you know?
3-Heads vs 2-Heads;
'Normal / 2-head' decks have an erase head and a 'combination' playback / record head that serves 'double duty' depending on whether it was being sent a 'record signal' or receiving a 'playback signal', thus the "2-heads". Most 'higher end' cassette tape decks / recorders offered '3-Heads' for superior 'recording' performance. The 'Third-head' was a separate playback head, positioned immediately after the record head to allow 'almost instantaneous' (about a third second behind, as a cassette shell only has 'so many openings') monitoring of the actual recorded signal on the tape, as opposed to simply monitoring the 'input' signal to the deck. However, the '3rd-head' 'generally' does nothing for playback of already recorded tapes. There's some credence to the argument that playback heads can have a closer 'gap' designed into them than record heads, so if you get a '3-head' deck that has a playback head with a closer gap, then it would (could) offer better playback performance. Possibly, if you check the specs (if available) and find that is the case, the heads aren't worn and the balance of the deck is of substantial quality. Many better 2-head decks offered playback heads in the 18-20kHz.
I get a lot of folks that are shopping for cassette decks, with only the purpose of 'playing back' their old tapes, but thinking they want a 'Three-Head Cassette Tape Deck' because they've been 'told' that it would be better quality. Since the third head does 'little to potentially nothing' for playback (except it does make doing final audio adjustments / fine biasing adjustments when servicing MUCH easier), there's minimal reason to hold out for that feature, nor to pay extra for it…unless you just want it, or you ARE going to be 'recording' or it's coming along on a deck that has other features you wish. Now if you are going to be 'recording' then I 'HIGHLY' recommend a deck with 'Tape Monitoring' via the third head, thus "3-Heads"!

ü Our technician has completely and EXTENSIVELY gone through and 'Certified' this unit cleaning inside and out, tape transport mechanism removed, cleaning and re-lubricating internal mechanisms and the balance of efforts listed below. (this was already a VERY CLEAN & LIKE NEW deck inside before we started our service work)

ü AC voltage set for 'North American' use, and Internal DC power supply tested to correct Voltages before any work commenced

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

ü Head rotating gears on both wells inspected with a jewelers loop prior to starting any restoration work, and found to be 'hairline' crack free.

ü Main Drive and Counter belts inspected and are in 'like new' cond.

ü Rubber pinch rollers have been reconditioned

ü One VERY important note about this deck. The spindles are 'gear driven' which means that it should WAY OUTLAST most other decks that utilize standard, rubber 'idler tires' for reel activation (everyone thinks that 'belts' are all you need to replace to make a cassette deck work.  While belts are important, it's almost always the 'idler tire' that is the "Achilles Heel"  of cassette decks and causes the VAST majority of cassette deck problems).

ü Both spindles in perfect alignment.

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

ü Head alignment and azimuth at 125Hz, 1kHz and 10kHz adjusted for BOTH directions on both decks for 'peak performance' with O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

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

ü Front panel removed and disassembled to allow cleaning of the Record and Balance potentiometers.

ü All LED's and fluorescent displays functioning well, with low current draw

ü FF, REW, & Play transport functions all test perfectly and controls tested for 'positive / accurate' responsive.

ü 'Mechanized' Eject door operates smoothly.

ü Tape Counter Function tested

ü Dolby NR circuits / function tested

ü 'Memory / Zero Return' function tested

ü Meters adjusted to even zero with symmetric with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Both Internal playback amplifier channels adjusted with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Meters adjusted to even zero with symmetric input with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Both Internal Record amplifier channels adjusted with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.
ü Pinch roller and heads all in GREAT condition!!!

ü Overall floor noise measured at >-60dB.

ü Speed adjusted internally to 100% accuracy BOTH directions, with 1kHz factory calibration tape and frequency counter (meaning 1kHz calibration tape plays back at 1000Hz +/- 1Hz)

ü Plays great and after full service and adjustment, records AMAZINGLY well w/ following results;

1kHz recorded @ 0dB with Dolby C engaged on Maxell XL-II (High bias) tapes plays back @ -2 dB L&R.

Full Bandwidth 'White Noise' recorded @ 0dB w/o NR engaged on Maxell XL-II (High bias) tapes plays back @ -3dB L&R


Full Bandwidth 'White Noise' recorded @ 0dB with Dolby C engaged on Maxell XL-II (High bias) tapes plays back @ 0dB L&R, which equals ZERO dB loss!!

"Real World" test, 'DDD' CD recorded at 0dB +/- 3dB with Dolby C engaged, on Maxell UDXL-II / High Bias tapes sounds great

Bottom line is this deck sounds amazing for playback or recording (always make sure you're playing back 'good quality' tape recordings)


ü Again, Cosmetically, the deck has a few 'battle scars' and isn't going to win any 'beauty contests', but makes up for it in performance.
Total technician time to restore 4+ HOURS!

- Record Level control
- Record Mute function

ü NEW, 'reel drive' tire installed for trouble-free service. (These are actually much more important to replace on this deck (and most) than the belts. Without these, the deck won't fast wind very well, and will likely 'eat tapes' as the 'take-up' reel won't turn properly)

ü All three Main Drive and Counter belts replaced for trouble-free service.

ü Rubber pinch rollers have been reconditioned

ü Flywheel 'belt surfaces' solvent cleaned

ü Bronze Flywheel bushings solvent cleaned

ü Entire flywheel assemblies re-lubed upon re-assembly

ü Interconnects on 'transport circuit board' repaired

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

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

ü Head alignment and azimuth at 125Hz, 1kHz and 10kHz adjusted for BOTH directions for 'peak performance' with O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü FF, REW, & Play transport functions all test perfectly and controls tested for 'positive / accurate' responsive w/ new idler tire installed.

ü 'Silicone Damped' Eject door operates smoothly.

ü Tape Counter 'Reset' button fabricated & tested

ü Tape Counter Function tested

ü Dolby NR circuits / function tested

ü 'Memory / Zero Return' function tested

ü Meters adjusted to even zero with symmetric with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Both Internal playback amplifier channels adjusted with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Meters adjusted to even zero with symmetric input with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Both Internal Record amplifier channels adjusted with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes.

ü Pinch roller and heads all in GREAT condition!!!

ü Overall floor noise measured at >-60dB.

üSpeed adjusted internally to 100% accuracy BOTH directions, with 1kHz factory calibration tape and frequency counter (meaning 1kHz calibration tape plays back at 1000Hz +/- 1Hz)

ü Cosmetically, there are some 'whiteish spots" that we weren't able to affect. 409, Alcohol, nor Naptha seemed to have any effect on them.

ü Plays great and after adjustment, records AMAZINGLY well w/ following results;

ü With White Noise recorded @ -0dB w/o Dolby engaged PB = -3dB & With White Noise recorded @ -10dB w/o Dolby engaged PB = 0dB

ü With White Noise recorded @ -10dB w/o Dolby engaged PB = -10dB & @ 10kHz w/o Dolby engaged PB = -10dB on Maxell UDXL-II / High Bias tape

ü With 1kHz recorded at 0dB with Dolby engaged on Maxell XL-II (high bias) tapes PB = -2dB

ü With 'ddd' CD recorded at 0dB with Dolby engaged; -3dB on Maxell UDXL-II / High Bias tape

Bottom line is this deck sounds great for playback or recording (always make sure you're playing back 'good quality' tape recordings)
Total technician time to restore 11+ HOURS!

____________________________

The Teac A-510 / A-500 with 'Dolby NR and IC Logic Transport', Stereo Cassette Tape Deck. Great deck for doing tape transfers if your tapes were recorded with no NR or with "Dolby B" or for making some awesome 'new' recordings or 'mix tapes' (hey, it's 'the thing' again). This deck is a pleasure to use, and has a great 'feel' due to it's size and transport function. As far as cosmetics, it's BEAUTIFUL. Was taken very good care of before it came to us, and is even more astounding now. Very impressive looking deck.

Teac A-510 Features include:
  

-  "Soft touch / IC LOGIC control" tape transport (allows you to switch between 'Fast Wind' or 'Play' modes without pressing 'Stop' w/ no fear of 'spilling / dumping tape')
- Selector for Normal (EX / I), CrO2 (SX / II) & Metal (ZX / IV) Tape Type
- 3-Position Selector for Tape Equalization for Normal (EX / I), CrO2 (SX / II) & Metal (ZX / IV) Tape Type on playback
- Dual Fluorescent VU Level Meters
- Analog Tape counter 
- Variable Output Level control (one of the most important features on a deck in our opinion)
- Dolby B NR
- Record Muting
- Real 'Potentiometer' Record level controls that are 'gear coupled' (meaning when you turn one, the other one responds as well. They can be turned independently for 'fine adjustment' as they're 'clutch coupled' as well)
- Memory Stop for counter
- Dual, Front mounted, 1/4", Microphone Jacks
- Front mounted, 1/4", Stereo Headphone jack
- RCA and DIN I/O's on rear panel
- Timer Play / Record function. (IMPORTANT NOTE ABOUT 'TIMER SWITCH' ON THIS DECK. If the 'Timer' switch is in any position other than "OFF", and the tape plays thru to 'Auto-Stop', then no other function on the deck will commence until the 'Timer' switch is turnted to "Off". That is what the 'sticker' on the top of the unit indicates (and we found to be the case))
- Multi-pin port on rear panel for optional wired remote, TEAC RC-90 (remote not included)

Teac A-510Specifications:
 
Track format: 
4 track / 2 channel
Motors:
 2x, 1x DC Coreless 'Reel', & 1x FG Servo Controlled DC 'Capstan'
Wow & Flutter (WRMS):

1-7/8 ips
Speed Deviation: 0.015% (we did not find ANY speed deviation when bench testing following restoration and / or auditioning
Harmonic Distortion / THD: <2.0% @ 1kHz & 0dB (High Bias Tapes)
S/N ratio w/ CrO2 tape:
>48db w/ Dolby dis-engaged (and Normal Bias Tapes)

Again, we have completely cleaned, refurbished / serviced and thoroughly tested this Teac A-510 cassette tape deck.
Great for transferring your no NR or Dolby B NR encoded tape collection to CD, Hard-drive or MP3 especially with the 'Tape EQ' selector for 'fine tuning' older tapes. Built very well! Again, not going to win any beauty contests, but performs decently. Due to it's size, overall feel, the 'input controls' and the 'transport control' this deck really is a blast to use. Comes with an 'e-copy / pdf download' of the TEAC A-510 / A-500 cassette tape deck service manual if the purchaser desires. Measures 18.6" wide x 13.5" deep x 7.25" tall and weighs a VERY HEAVY 24 lbs unpacked. Just in-case you 'too casually' read past that last little bit,
IT'S A TWENTY-FOUR POUND CASSETTE DECK!
Includes our standard 90 day limited warranty.

- NOTES ON PURCHASING A VINTAGE CASSETTE DECK -

I own and have owned ‘hundreds’ of cassette decks. I started selling them ‘new’ in the early 1980’s.
Very few of the decks that we have on our ‘incoming’ shelves will function to any degree of ‘practical usability’, if at all, in their ‘as found’ condition. So it amazes me at all the articles out there on “How to Buy a Used / Vintage Cassette Deck”, and no one seems to mention how the ‘clock needs to be rolled back’ 30-40 years on one to get to a level of ‘practical usefulness’. They all want to mention to make sure it’s got the right ‘features’ for what you need,  that it’s in “good condition” (typically referring to its often purported, “minty” looks),  that the shipping is “reasonable”,  the methods of payment work for you,  and that the ‘sellers feedback rating’ is adequate….
WHAT ABOUT IT’S INTERNAL CONDITION????? IT’S GOT 20-40 YEARS UNDER THE HOOD!!!
      There’s lots of ‘rubber’ and ‘lubricated parts’ inside a cassette deck. ‘Time’ is NOT a friend to either. Rubber can do a few things. It can crack, stretch, break, glaze over (think about how a ‘pencil eraser’ gets after about a year in a drawer), or turn back to its original form, which is a ‘gooey / tar’ substance. Oil and grease ‘gel up’ and stop being lubes, and start becoming ‘glues’ (think the grease caked under an old / vintage car / tractor. It has to be ‘chipped’ away with a putty knife).  Both of those aspects and others affect a tape deck’s (or turntable, or VCR or camcorder, or CD / DVD player, or film projector, or just about anything that is powered by electricity and has moving parts (AND THERE’S A LOT OF MOVING PARTS IN A CASSETTE DECK) performance. Most folks assume that if you simply 'change the belt(s), then the deck is 'good to go'. "Not even close". Most cassette decks also utilize an 'idler tire' to drive the tape reels, not only for 'Fast Wind' functions, but also for 'Take-up' reel function. This tire becomes 'glazed', cracked, deformed and / or disintegrated, and a deck WILL NOT function correctly with 'tire' issues. The 'kicker' is that the 'idler tire' is almost always 'buried' deep within the transport mechanism which typically requires a near complete disassembly of the entire tape transport to even asses if a replacement tire can be found, an available one modified, or if one can be fabricated.
Thus following is a list of questions to ask about any tape deck…

          How is its overall ‘Speed’? Inaccurate speed is one of the first ‘tell-tale’ sign of a decks overall heath. You won’t likely be able to tell without an accurate ‘speed / test tone / calibration’ tape and a frequency counter. If you’re not a musician, not ‘musically inclined’, or are ‘tone deaf’ maybe you won’t notice, but most folks will notice ‘something is not quite right’ when listening to a slow (or occasionally fast) running tape. Just throwing on a new belt, doesn’t address speed accuracy. Most mechanisms will need to be disassembled, cleaned and re-lubed before any speed adjustments can be attempted.

          How ‘Steady’ is the speed? This refers to ‘WOW & Flutter’. This generally won’t be noticed until you put on a tape with a ‘steady tone’ or a musical piece with sustained piano notes. Then ‘Flutter’ issues will drive you nuts. Also can be noticed with sustained string instruments. Just wait till there’s violin with vibrato, then added on top is ‘out of time’ vibrato caused from excessive ‘Flutter’ of the tape transport. If someone just throws any selection of music in, or a 'spoken word' tape, they'll likely not notice the 'Flutter' issue.  WOW’ is less of an issue in cassette decks, but can occasionally be caused by ill-fitting / wrong belts being installed.

          Does the deck ‘fast wind’ at ANY AND ALL positions on the tape, and will fast wind, BOTH WAYS throughout an entire tape,...repeatedly...Every time? While playing does the ‘take up’ pulley / reel run correctly, or is it ‘jerky’. Is ‘fast wind’ (in either or both directions) smooth, or jerky. It will typically be jerky and intermittent if it functions at all. If it doesn't turn correctly / sufficiently in 'Playback' mode, that will cause the deck to 'eat tapes'!
This is caused by a ‘glazed’ / cracked ‘idler tire’, and about 99.999999% of decks are going to have a glazed or cracked or otherwise deteriorated idler tire’. It's 'decades' old rubber.  It almost HAS to be compromised.  You usually can't 'dodge physics'.  AND those things are not easy to address. The idler tire will almost always be ‘buried’ a few layer inside the transport. Then once you get there you go on the hunt for a replacement, only to find that there were dozens or hundreds of rubber, idler tires made, only a few of which are still available, and none of which will fit correctly. So now you have to make the choice (at least of you want to move forward with a decks restoration) as to whether you substitute an ‘O-ring’ (often works as a sub) or you take a tire that is close to fitting, and modify it to function correctly.

     How is the condition of the heads, regarding 'head wear'? It takes and 'experienced eye' to 'visually' estimate the condition of tape heads. Excessively worn heads, will never sound the way they should, with any amount of adjustment, and you can't just go into your local 7-11 and pick up a new set. Replacement heads for a specific deck, will likely need to come from another of the same (or darn close) specific deck. Having the heads 'lapped' was once a sometimes viable possibility, but that is, for the most part, a 'long, lost art'.  Even if you manage to acquire replacement heads, they have to be installed correctly. That will require alignment tapes and test gear (O-scope and / or milli-Volt meters) and a lot of patience.

     If the deck is ‘auto-reverse’, how’s the condition of the gear in the mechanism that ‘spins the head’? They are commonly, slightly ‘cracked’. There is note a practical fix for that. The head will go part way and ‘lock up’. If you can get it to go ‘back’ to its original position, just leave it, and accept that the deck is not ‘auto-reverse’.

     When the tape gets to the end of it's travel in play and fast wind modes, does the decks 'auto-stop' mechanism work? Every time?

     Does the tape counter work, and spin smoothly throughout the entire length of the tape? Every time?

        How’s the ‘azimuth’. Yes, I know it’s not a word that you use every day, but it’s vitally important on a tape deck. When the azimuth is out of alignment, a tape will sound ‘muffled’ (loss of treble) and / or ‘out of phase’ (not much bass). While you can use a ‘pre-recorded’ tape and get it close, it’s really only adjusted correctly and COMPLETELY by utilizing a ‘calibrated alignment’ tape and an O’Scope or at least a ‘milli-Volt’ meter.

          How many ‘dB’ down does the deck playback from its recording level? If you record a signal at “0dB”, how far does playback deviate from that? You should usually expect 3-6dB if the deck is in ‘reasonable’ condition. If it’s down 10 or 12dB (or more) you’re not likely going to be very happy with its recording quality. Unless it’s simply due to dirty heads, addressing this is fairly complicated for all but the technically qualified.

           Is playback even out of both channels and via both meters? You can’t just put on your favorite tape of ‘Death-Polka Favorites’ (or some other 'recorded program material' and listen to it to make an accurate determination. You would need a calibrated test tape (with 'constant' test tones), and an O’scope, or at least a millivolt meter to first make sure the playback head is in alignment, then the internal playback amplifiers are producing an ‘even amplitude’ and then that the meters are both ‘mechanically’ adjusted correctly and that their ‘voltage feed’ is evenly adjusted. Don’t know what any of that means? Then I wouldn’t be ‘messing with it’.

Do you hear any 'crinkling / scrunching' noises with your ear right up next to the transport, and / or when you pull out a tape that has been played on it, is there evidence of 'crinkling / wrinkles / creasing' on the tape section that just went past the pinch roller?

          Is there a loud, obnoxious ‘motor boating’ sound that and or your meter(s) are cyclically ‘pegging’? No. How about after the third time of putting the deck into record mode? Or the 6th time or the 20th time? Then the there’s a problem with the internal record switch (or it needs to be flooded / cleaned). (this issue is usually only a potential problem on a deck with a ‘mechanical internal record switch’, and not more ‘modern decks’ that use ‘electronics’ to switch the deck in and out of record)
  
    Does the deck make any extraneous noises when in play / record, such as squeaks, growls, scrapes, grinds etc? if not immediately, how about after 15 minutes, a half hour, an hour or a day? In all modes?

    Are the ‘Recording Level’ control pots ‘quiet’ or do they need to be cleaned?

    Do the “Source / Monitor” or “Tape EQ” switches quiet or do they make noise and need to be cleaned?

    If the deck has ‘Auto-Tape-Type’ sensing, is it triggering correctly? If not, that could mean an issue with the mechanism trigger tab, or a dirty / compromised micro switch.

    If the deck is equipped with any type of noise reduction ie; Dolby B, C, dbx etc, is if functioning properly? We don’t see issues with that often, but it does happen.

       Is the deck quiet when playing back a ‘blank tape’ or better yet, a cassette ‘shell’ with no tape in it? (some decks will not allow this test easily, as it’s ‘auto-stop’ mechanism is triggered by the tape counter, which is typically tied to the ‘supply’ reel and if that reel is not moving then the deck will go into ‘auto-stop’ mode.) This is ‘floor noise’ and is not to be confused simply with ‘tape hiss’, which is why we want to hear the transport moving without tape passing the playback head.

     How is the 'quality' of the recording and playback? Bad, distorted recordings can also be due to Bias issues (besides the above mentioned "worn heads", azimuth alignment errors and dirty controls and switches.

    Are all of the indicators and lights working? These aren’t typically ‘functional deal breakers’, but can definitely increase or decrease ‘curb appeal’.

If 'analog', do the meters settle at their left most index line? Do they both respond quickly? Do they 'stick' at any point in their travel? If 'really pegged' do the get stuck at the top?

    Does the ‘well door’ close and latch, EVERY TIME and correctly, REPEATEDLY?

Those would be most of the ‘high points’ regarding the functionality of a tape deck.   Once you, or someone technically qualified has addressed AT LEAST ALL of the above, then we can talk about how ‘minty-fresh’ it’s cosmetics are.

      I get the question of, “what’s the best brand / model” of tape deck out there. Well, 25-50 years ago, when you could go to a few ‘real audio shops’ and take your pick of a dozen or two NEW tape decks, that question held much validity. Now my opinion of the "which is the best deck", is the “one that has been properly refurbished / restored / fully service to a level of ‘proper utility’, recently, by someone qualified to do so”.

A QUESTION:
    Most folks know the difference, without too much thought, between a Chevrolet ‘Corvette’ and a Chevrolet ‘Chevette’. If I ask most folks "which is a better car, a ‘Corvette’ or a ‘Chevette’", most folks will answer "the Corvette” (barring all the arguments based on other personal opinions)…Now, I’ll give you the rest of the story. The Corvette has been sitting in a barn for the past 25 years, and hasn’t been started since it was parked there originally. Or it was in a flood. Or it’s had a dog living it, or a rat has built a home in the dashboard, or the engine was blown by the 'now deceased owner’s son', or, or, or…
     Now the Chevette has just been thru a qualified auto repair shop, and had the engine compression checked (and was within spec), new plugs / wires / dist cap, timing adjusted, new starter, alternator checked for charging, new battery, the coolant flushed, the clutch replaced, the brake system flushed, new calipers, drums and shoes, new belts, carb rebuilt and properly jetted, vacuum lines checked for leaks and replaced, air conditioner serviced, new seat covers, new tires, new wiper blades, windshield cleaner system replaced, cracked windshield replaced, all lights tested / replaced, horn checked, wiper motor / mechanism checked / lubed, and thoroughly test driven around town, starting and stopping, on the highway at all speeds. It was started in the cold weather, and once warm, started again. Repeatedly. It is pretty much doing what it did when new.  And you need to take a trip across the country tomorrow.  Now I ask again,  "which is the better car?"

ü Our technician has completely and EXTENSIVELY gone through and 'Certified' this unit which involves total disassembly of the transport, cleaning inside and out, COMPLETELY DISASSEMBLING, cleaning and re-lubricating all internal mechanisms and the balance of efforts listed below (incredibly difficult on this deck!!!).

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

ü Main Capstan / Flywheel belts replaced w/ #42-450 & #42-980.

ü Counter belts replaced w/ #42-260 & #42-1060.

ü Rubber pinch roller mechanism bushings & axles cleaned of old lube, reconditioned and re-lubed.

ü Capstans motor had it's bronze bushings lubed w/ 30wt

ü Capstans cleaned / burnished

ü All internal trim pots, switches and controls cleaned and tested for noise-free function.

ü All meter lamps and LED indicators working fine.

ü Both hub spindles in perfect alignment.

ü "FF, REW, & Play transport functions all test and controls tested for 'positive / accurate' responsive" is what we normally like to say, but due to the internal design of this one, we were not able to get it to perform 100%, EVERY time. Occasionally the 'STOP' button will have to be pressed a time or two, or another button will need to be pressed to then be able to engage 'STOP'. Other buttons sometimes 'hang up' temporarily, but usually selecting another transport function will 're-set' them as they're 'self cancelling / mechanical' with an internal mechanism that was unusually difficult to service and get to the current 'usable' state.

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

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

ü Head alignment and azimuth at 125Hz, 1kHz and 10kHz adjusted for BOTH directions for 'peak performance' with O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output for PLAYBACK..

ü Both Internal playback amplifier channels adjusted with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output for PLAYBACK..

ü Meters adjusted to even zero with symmetric input with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output for PLAYBACK.

ü Both Internal Record amplifier channels adjusted with Volt meter, O-Scope and sine-wave generators and 'pink / white noise sources', however we were not able to get great recordings. The left channel is often 'low / and distorted' on 'Recording' (sounds fine as a 'PLAYBACK' deck).

ü Pinch roller and heads all in GREAT condition!!!

ü Speed adjusted to 100% accuracy BOTH directions, with with TEAC MTT-257H 1kHz factory calibration tape (meaning 1kHz calibration tape plays back at 1000Hz +/- 1 Hz)

ü Pinch roller re-surfaced, and in GREAT condition!!!

ü Tape Counter works well

ü Speed adjusted internally to 100% accuracy with 1kHz factory test tape (meaning 1kHz calibration tape plays back at 1000Hz +/- 1Hz) (utilized TEAC MTT-257H)

ü Floor noise measured at -60dBm

So again, this deck was ultimately passed as a 'Playback' deck.

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 (there’s probably issues we didn’t or couldn’t 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 you’re 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 they’re generally a ‘single digit percentage’ of what’s out there available for sale.

SOLD 4/22/20
SHIPPING TO SHADRACH IN CANADA


ü Our technician has completely and EXTENSIVELY gone through and 'Certified' this unit which involves total disassembly of the transport, cleaning inside and out, COMPLETELY DISASSEMBLING, cleaning and re-lubricating all internal mechanisms and the balance of efforts listed below.

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

ü Spindles are GEAR DRIVEN which means NO idler tires / wheels to glaze over, crack and mis-behave with none of the typically associated ills.

ü Counter belt - NO counter belt. It's GEAR DRIVEN!!!

ü Main Capstan / Flywheel belt reconditioned.

ü Rubber pinch roller mechanism bushings & axles cleaned of old lube, reconditioned and re-lubed.

ü Capstans cleaned / burnished

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

ü All Fluorescent displays and LED's working fine.

ü Both hub spindles in perfect alignment and end locks intact and staying put.

ü FF, REW, & Play transport functions all test perfectly and controls tested for 'positive / accurate' responsive.

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

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

ü Head alignment and azimuth at 125Hz, 1kHz and 10kHz adjusted for BOTH directions for 'peak performance' with O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Both Internal playback amplifier channels adjusted with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Meters adjusted to even zero with symmetric input with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Both Internal Record amplifier channels adjusted with Volt meter, O-Scope and sine-wave generators and 'pink / white noise sources'. Both channels now even output.

ü Pinch roller and heads all in GREAT condition!!!

ü Speed adjusted to 100% accuracy BOTH directions, with with TEAC MTT-257H 1kHz factory calibration tape (meaning 1kHz calibration tape plays back at 1000Hz +/- 1 Hz)

ü Pinch roller re-surfaced, and in GREAT condition!!!

ü Playback meters zero with factory test tone tape.

ü Tape Counter and 'Memory' Function tested

ü White Noise recorded @ 0dB w/ Dolby-C engaged = PB @ -2dB on Maxell UDXL-II / High Bias tapes

ü 1kHz Sine-wave recorded @ 0dB w/ Dolby-C engaged = PB @ -1.5dB on Maxell UDXL-II / High Bias tapes

ü 'ddd' CD recorded recorded @ 0dB w/ Dolby-C engaged = PB @ ~ -1dB on Maxell UDXL-II / High Bias tapes


ü 1kHz Sine-wave recorded @ 0dB w/ *dbx engaged = PB @ -1.5dB on Maxell UDXL-II / High Bias tapes.

ü 'ddd' CD recorded recorded @ +3dB w/ *dbx engaged = PB @ ~ -6dB on Maxell UDXL-II / High Bias tapes
So this is the one aspect of the deck that we were not able to 'practically' rectify. It's record and playback capability with dbx NR engaged is about 9dB down. It probably needs it's 'dbx chips' replaced, but beyond the scope of practicality for us and this deck.


ü Speed adjusted internally to 100% accuracy with 1kHz factory test tape (meaning 1kHz calibration tape plays back at 1000Hz +/- 1Hz) (utilized TEAC MTT-257H)

ü Floor noise measured at -60dBm

Total technician time to restore
~5 HOURS!

ü Our technician has completely and EXTENSIVELY gone through and 'Certified' this unit which involves complete removal and disassembly of the entire transport, cleaning inside and out, DISASSEMBLING, cleaning and re-lubricating all internal mechanisms and the balance of efforts listed below.

ü Heads inspected for excessive wear (obviously we do this 'early on' as 'excessive' wear will usually negate any further restoration work). These have virtually NO visible wear to them.

ü Capstan motor spindle bushing re-lubed

ü Capstan burnished

ü Internal DC power supply tested

ü 'Reel drive' tires reconditioned installed for trouble-free service. (These are actually much more important to replace on this deck (and most) than the belts. Without these, the deck won't fast wind very well, and will likely 'eat tapes' as the 'take-up' reel won't turn properly)

ü New internal Drive (#42-340) and Counter (#42-470) belts installed for trouble-free service.

ü Rubber pinch rollers have been reconditioned

ü Both Flywheel 'belt surfaces' solvent cleaned

ü Bronze Flywheel bushings solvent cleaned

ü Both Flywheel thrust pads cleaned

ü Both Brake pads replaced

ü Entire flywheel assemblies re-lubed upon re-assembly

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

ü All original illumination working well

ü Head alignments and azimuth at 125Hz, 1kHz and 10kHz adjusted for 'peak performance' with O-Scope and original TEAC alignment tape

ü All internal pots, switches and controls cleaned and tested. Performing well now, with a bit of residual noise on one of the 'output' pots (fortunately, once 'output' pots on tape decks are 'set', they're usually not moved).

ü Both spindles in perfect alignment.

ü FF, REW, & Play transport functions all test perfectly and controls tested for 'positive / accurate' responsive.

ü 'Silicone Damped' Eject door operates smoothly following disassembly and re-lubing w/ silicone gel (must 'hold' down "Eject" button on this series until door releases)

ü Tape Counter Function tested

ü Dolby NR circuits / function tested

ü 'Memory / Zero Return' function tested

ü Heads are in great condition

ü Internal playback levels adjusted for even playback w/ alignment tape, Oscilloscope, and mVAC meter

ü Playback meters adjusted for 'playback' zero'd with factory test tone tape.

ü Internal Record amplifier channels adjusted for 'even output'

ü Pinch roller and heads all in GREAT condition!!!

ü Overall floor noise measured at >-60dB.

ü Speed adjusted internally to 100% accuracy BOTH directions, with 1kHz factory calibration tape and frequency counter (meaning 1kHz calibration tape plays back at 1000Hz +/- 1Hz)

ü Plays great and after adjustment, records AMAZINGLY well w/ following results;
With 1kHz recorded at 0dB / 1 7/8ips / w/o Dolby engaged; -1.25dB on Maxell UDXL-II / High Bias tapes
With DDD CD recorded at 0dB / 1 7/8ips / w & w/o Dolby engaged; -1 to -2 dB on Maxell UDXL-II / High Bias tapes

Bottom line is this deck sounds amazing for playback or recording (always make sure you're playing back 'good quality' tape recordings)
Total technician time to restore
8+ HOURS!

(Tech note: This model deck is "VERY SERVICEABLE" since it's in their 'Pro-Line'.
(Only remaining issues would be that REW is a bit noisy when nearing completion on most brands of tapes and Right output pot still a bit noisy when manipulated)

____________________________

The Tascam 133, Pro-Series, 2-SPEED, Stereo Cassette Tape Deck. Great deck for a 'project recording studio' as a 'mastering deck' (utilizing the 'High Speed'). With an original MSRP of over $1500, this was one of Tascams most expensive cassette decks ever. Of course also makes an incredible 'home system' deck and of also a great deck for doing your tape transfers if your tapes were recorded with no NR or with "Dolby B". Think of making some awesome 'new' recordings or 'mix tapes' (hey, it's 'the thing' again). This deck is a pleasure to use, and has a great 'feel' due to it's size and transport function. As this was made for 'video / radio' production it limits frequency response to 15k (per FCC limits), but makes up for it in robust build quality.

TASCAM 133 Features include:


- Two Speeds; 1 7/8 ips (normal) and 3.75 ips (HIGH Speed for best recording quality)

- Dolby B NR
- Rear I/O RCA jacks for connecting external dbx (or other NR) unit
- Heavy duty transport featuring 'oversized' capstan motor, and large flywheel
- "Soft touch / IC Logic control" tape transport
- Triple Analog VU Level Meters
- Digital Tape counter 
- Variable Output Level 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)
- Real 'Potentiometer' Record level controls
- Memory Stop / Repeat Play and for 'Rewind' for counter
- Dual, Front mounted, 1/4", Microphone Jacks
- Front mounted, 1/4", Stereo Headphone jack w/ Level / volume control
- Multi-pin port on rear panel for any optional dbx NR unit (not included)
- Multi-pin port on rear panel for optional wired remote, (Tascam RC-133 remote not included)

TASCAM 133 Specifications:
 
Track format: 
4 track / 3 channel
Motors:
 2x 1x DC 'Reel', & 1x FG Servo Controlled DC 'Capstan'
Freq Response w/ Philips tape;
30Hz to 15kHz +/- 3dB @ 'High Speed'
Wow & Flutter (WRMS):
as low as; 0.06% @ 'High Speed' & 0.04% @ Normal Speed
Tape Speeds:
1-7/8 ips & 3.75 ips
Harmonic Distortion / THD: <1.5% @ 1kHz & 0dB (High Bias Tapes)
Speed Accuracy:
<+/-0.5% deviation either speed
Preset Bias frequency:
60kHz
Erasure:
>65dB @ 1kHz
S/N ratio:
>55db w/ Dolby dis-engaged (and High Bias Tapes @ either speed)
Adjacent Track Crosstalk: >45dB @ 1kHz (one of the best we've seen)
Fast Wind time: <90sec on C-60 Tapes)

  
Again, we have completely cleaned, refurbished / serviced and thoroughly tested this Tascam 133, 'PRO' cassette tape deck.
Makes fabulous recordings. Also great for transferring your no NR or Dolby B NR encoded tape collection to CD, Hard-drive or MP3 especially with the 'Tape EQ' selector for 'fine tuning' older tapes. Built very well! Due to it's size, overall feel, the 'input controls' and the 'transport control' this deck really is a blast to use. Would make a great '2-Track' deck to match your Tascam 234 'Multi-Track' if you have one. Sorry, but we did not get the rack ears so no covering over face plate ends on the sides. Comes with an e-copy / pdf download of the Tascam 133 owners / user / instruction manual and the service manual if the purchaser desires.
Measures 19" wide x 13.5" deep x 5.75" tall and weighs a heavy 20 lbs unpacked.
Includes our standard 90 day limited warranty.

ü Our technician has adjusted, EXTENSIVELY tested and 'Certified' this unit

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

ü GEAR DRIVE reel tables, so none of the typical 'cassette deck' worries about sluggish Fast Wind or Tape Eating = trouble-free service.

ü Rubber pinch roller has been reconditioned

ü Capstans cleaned

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

ü Head alignments and azimuth at both 1kHz and 10kHz adjusted for BOTH directions (averaged) for 'peak performance' with O-Scope

ü Heads are in great condition

ü Playback meters adjusted for 'playback' zero'd with factory test tone tape.

ü Head alignment and azimuth at 125Hz, 1kHz and 10kHz adjusted for BOTH directions for 'peak performance' with O-Scope and w/ SONY A100 and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Both Internal playback amplifier channels adjusted with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü FF, REW, & Play transport functions all test perfectly and controls tested for 'positive / accurate' responsive.

ü Eject door operates smoothly.

ü ALL Tape Counter Functions tested

ü Dolby B & C NR circuits / function tested

ü Floor noise measured to -60dBm

ü Cosmetics are decent with a only few scuffs / scratches

ü Plays perfectly and after adjustment, records very well at -2dB = 0dB down on about any formulation of tape (as it's got 'fine bias'). We did 'test recordings' of Pink Noise and 'ddd' CD's on Maxell 'XL-II' High Bias. We found that they all performed VERY well on this particular deck (and most decks). We did however find that the deck likes to record at about -20dB on the meters, for 'smoother saturation' of tape (which is the industry standard, we just like to 'push them'). Again, we really didn't have a favorite, plus the deck has adjustable Bias (although we left it 'centered' for our tests).
Total technician time to restore 3+
hours.

Great deck for doing your tape transfers if your tapes were recorded with no NR or with "Dolby B" or for making some awesome 'new' recordings or 'mix tapes' (hey, it's 'the thing' again). This deck is a pleasure to use, and has a great 'feel' due to it's size and transport function.
As far as cosmetics, it's BEAUTIFUL. Just a couple little minor scuffs / dings on the included, but originally optional wood grained case (see photos above). Was taken very good care of before it came to us, and is even more astounding now. The deck and the wood grain case could convince you that time had rolled back almost 40 years, and you were seeing it at the original store's retail display.

AKAI GX-F60R Features include:
  

- "Twin-Field / Super GX Head" (features separate 'gap sizes' for Playback and Recording in a single R/P head)
- 'Quick Infrared' Auto Reverse (Reverses at 'beginning' of 'leader / tape' splice, instead of playing all the way thru the leader to the point of 'Auto-Stop' resistance, the needing to play back through the leader just to get to the recorded material on side B)

- Triple-Mode Auto-Reverse

- "Soft touch / IC Logic control" tape transport
(allows you to switch between 'Fast Wind' or 'Play' modes without pressing 'Stop' w/ no fear of 'spilling / dumping tape')
- Selector for two positions of Normal (EX / I), CrO2 (SX / II) & Metal (ZX / IV) Tape Type
- Dual Fluorescent VU Level Meters
- Analog Tape Counter
- Built-in MPX filter for killing the 19kHz pilot tone in FM transmissions
- Variable Output Level 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)
- Dolby B NR
- Record Muting
- 'Auto-Space' records a 4-second space prior to 'stop' when engaged.
- Real 'Potentiometer' Record level controls that are 'friction-coupled' (meaning when you turn one, the other one responds as well. They can be turned independently for 'fine adjustment' as they're 'clutch coupled' as well)
- Memory Stop / Repeat for counter
- Dual, Front mounted, 1/4", Microphone Jacks
- Front mounted, 1/4", Stereo Headphone jack
- Timer Play / Record function.
- Standard RCA I/O jacks as well as DIN
- Multi-pin port on rear panel for optional wired remote, Akai RC-21 (remote not included)

ü Our technician has completely and EXTENSIVELY gone through and 'Certified' this unit which involves total disassembly of the transport, cleaning inside and out, COMPLETELY DISASSEMBLING, cleaning and re-lubricating all internal mechanisms and the balance of efforts listed below.

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

ü VERY DIFFICULT TO ACCESS, 'Reel Drive Tire' removed and replaced with a new one (#R-209). (These are actually much more important to replace on this deck (and most) than the belts. Without these, the deck won't fast wind very well, and will likely 'eat tapes' as the 'take-up' reel won't turn properly)

ü Reel drive belt replaced w/ #42-160.

ü Main Capstan / Flywheel belt reconditioned.

ü Rubber pinch roller mechanism bushing & axle cleaned of old, 'varnished lube', reconditioned and re-lubed.

ü Capstan burnished

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

ü 'Servo-Face' mechanism completely disassembled, overhauled and re-assembled. (actually worked fine prior to refurbishment, but we did 'proactive maintenance' so should be good for a long time to come)

ü Multiple solder joints re-flowed, primarily on the landing pads of the 'control pots / switches'.

ü All Fluorescent displays and LED's working fine.

ü Both hub spindles in perfect alignment.

ü  FF, REW, & Play transport functions all test perfectly and controls tested for 'positive / accurate' responsive.

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

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

ü Head alignment and azimuth at 125Hz, 1kHz and 10kHz adjusted for BOTH directions for 'peak performance' with O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Meters adjusted to even zero with symmetric with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Both Internal playback amplifier channels adjusted with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Meters adjusted to even zero with symmetric input with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Both Internal Record amplifier channels adjusted with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Pinch roller and heads all in GREAT condition!!!

ü Speed adjusted to 100% accuracy BOTH directions, with 1kHz factory calibration tape (meaning 1kHz calibration tape plays back at 1000Hz +/- 1Hz)

ü Pinch roller re-surfaced, and in GREAT condition!!!

ü Playback meters zero with factory test tone tape.

ü Tape Counter and 'Memory' Function tested

ü White Noise recorded @ 0dB w/ Dolby-C engaged = PB @ -2dB on Maxell UDXL-II / High Bias tapes

ü 1kHz Sine-wave recorded @ 0dB w/ Dolby-C engaged = PB @ -1dB on Maxell UDXL-II / High Bias tapes

ü 'ddd' CD recorded recorded @ 0dB w/ Dolby-C engaged = PB @ ~ -2dB on Maxell UDXL-II / High Bias tapes

ü Speed adjusted internally to 100% accuracy with 1kHz factory test tape (meaning 1kHz calibration tape plays back at 1000Hz +/- 1Hz) (utilized TEAC MTT-257H)

ü Floor noise measured at -60dBm

ü Our technician has completely and EXTENSIVELY gone through and 'Certified' this unit which involves complete removal and disassembly of the transport (not an easy task on this deck), cleaning inside and out, DISASSEMBLING, cleaning and re-lubricating all internal mechanisms and the balance of efforts listed below.



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

ü Head rotating gear inspected with a jewelers loop prior to starting any restoration work, and found to be 'hairline' crack free.

ü 'reel drive' tire reconditioned for years of trouble-free service.

ü All new internal Drive and Counter belts replaced for years of trouble-free service.

*ü Following initial service, we determined there was audibly detectable Wow & Flutter, so we changed the capstan belt again, and eliminated it.

ü Rubber pinch roller has been reconditioned

ü Capstan burnished

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

ü Head alignments and azimuth at both 1kHz and 10kHz adjusted for BOTH directions for 'peak performance' with O-Scope

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

ü Both spindles in perfect alignment.

ü FF, REW, & Play transport functions all test perfectly and controls tested for 'positive / accurate' responsive.

ü Eject door operates smoothly following repairs.

ü Tape Counter Function tested

ü Dolby B & C NR circuits / function tested

ü 'Memory / Zero Return' function tested

ü Heads are in great condition

ü Internal playback levels adjusted for even playback w/ alignment tape, Oscilloscope, and mVAC meter

ü Internal Record amplifier channels adjusted for 'even output'

ü Meters adjusted to within 1.5dB with symmetric input.

ü Pinch roller and heads all in GREAT condition!!!

ü Both level meters playback even.

ü Speed adjusted to 100% accuracy BOTH directions, with 1kHz factory calibration tape (meaning 1kHz calibration tape plays back at 1000Hz +/- 1Hz) (VERY difficult to do on this deck by the way)

ü Cosmetically, it's definitely not going to "win any beauty contests" (see above 'horizontal' photo collage), but it makes up for it in performance.

ü Plays perfectly and after adjustment, records AMAZINGLY well at -1dB! on Maxell UDXL-II tapes and -.5dB on Maxell UR / Normal Bias tapes (but 'top end' will not be as good as on CrO2). (Following the extensive restoration, we did 'test recordings' of a 'ddd' CD on 6 tapes; Sony HF Normal Bias -3dB, Fuji Normal Bias -2.5dB, TDK Normal Bias -1.5dB, Maxell Normal Bias, TDK 'SA' High Bias -2dB (didn't saturate as well as the Maxell UDXL-II), and Maxell 'XL-II' High Bias. We found that for Normal and High Bias, of those tapes tested, both "Maxells" performed well on this particular deck. The Maxell's did however much 'outshine' the TDK's for being able to 'over saturate' on the levels. While doing the test recording's, it became apparent that the recorded sound was fairly remarkable.
Total technician time to restore 17.5 HOURS!

ü Our technician has completely and EXTENSIVELY gone through and 'Certified' this unit cleaning inside and out, DISASSEMBLING, cleaning and re-lubricating internal mechanisms and the balance of efforts listed below. (this was already a VERY CLEAN & LIKE NEW deck inside before we started our service work)

ü AC voltage set for 'North American' use, and Internal DC power supply tested to correct Voltages before any work commenced

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

ü Head rotating gears on both wells inspected with a jewelers loop prior to starting any restoration work, and found to be 'hairline' crack free.

ü Main Drive and Counter belts inspected and are in 'like new' cond.

ü Rubber pinch rollers have been reconditioned

ü One VERY important note about this deck. The spindles are 'gear driven' which means that it should WAY OUTLAST most other decks that utilize standard, rubber 'idler tires' for reel activation (everyone thinks that 'belts' are all you need to replace to make a cassette deck work.  While belts are important, it's almost always the 'idler tire' that is the "Achilles Heel"  of cassette decks and causes the VAST majority of cassette deck problems).

ü Both spindles in perfect alignment.

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

ü Head alignment and azimuth at 125Hz, 1kHz and 10kHz adjusted for BOTH directions on both decks for 'peak performance' with O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

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

ü Front panel removed and disassembled to allow cleaning of the Record and Balance potentiometers.

ü All LED's and fluorescent displays functioning well, with low current draw

ü FF, REW, & Play transport functions all test perfectly and controls tested for 'positive / accurate' responsive.

ü 'Mechanized' Eject door operates smoothly.

ü Tape Counter Function tested

ü Dolby NR circuits / function tested

ü 'Memory / Zero Return' function tested

ü Meters adjusted to even zero with symmetric with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Both Internal playback amplifier channels adjusted with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Meters adjusted to even zero with symmetric input with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Both Internal Record amplifier channels adjusted with Volt meter, O-Scope and w/ STL and TEAC MTT-257H calibration / alignment tapes. Both channels now even output.

ü Pinch rollers and heads all in GREAT condition!!!

ü Speed adjusted to 100% accuracy BOTH directions, with 1kHz, TEAC MTT, factory calibration tape (meaning 1kHz calibration tape plays back at 1000Hz +/- 1Hz)

ü Pinch roller and heads all in GREAT condition!!!

ü Overall floor noise measured at >-60dB.

ü Speed adjusted internally to 100% accuracy BOTH directions, with 1kHz factory calibration tape and frequency counter (meaning 1kHz calibration tape plays back at 1000Hz +/- 1Hz)

ü Plays great and after full service and adjustment, records AMAZINGLY well w/ following results;

1kHz recorded @ +3dB with Dolby C engaged on Maxell XL-II (High bias) tapes plays back @ +3 dB L&R, which equals ZERO dB loss!! (same results with no NR)

Full Bandwidth 'Pink Noise' recorded @ 0dB with Dolby C engaged on Maxell XL-II (High bias) tapes plays back @ 0dB L&R, which equals ZERO dB loss!!

10k was down 5dB or less across the board.
White noise was down ~ 5dB recorded at -5dB and -10dB on Deck 1
White noise was down ~ 2dB recorded at -5dB and -0dB recorded at -10 on Deck 2

"Real World" test, 'DDD' CD recorded at +4dB with Dolby C engaged, on Maxell UDXL-II / High Bias tapes equals +4dB. Again, ZERO dB loss!!!

Bottom line is this deck sounds amazing for playback or recording (always make sure you're playing back 'good quality' tape recordings)

ü Cosmetically, the deck looks near new. Just a few very minor scuffs.
Total technician time to restore
5+ HOURS!

- Record Level control
- Record Mute function
- Timer Play / Record / Off selector
- 1/4" Stereo Headphone jack
 - Wireless Remote Control (INCLUDED)

Did you know?
Technics; The name Technics was introduced as a brand name for premium loudspeakers marketed domestically by Matsushita in 1965. In 1969, they introduced the SP-10, the first direct-drive turntable model for the professional market, and in 1971 the SL-1100 for the consumer market. The SL-1200 has since it's inception been the 'standard' of the industry for DJ's around the world. Most of there turntables are of 'industry standard' quality, even on the 'low-end' of the price scale, for most of their model years.
Technics was the first to introduce 'auto-reverse' (1972) into cassette decks (some would say to the detriment of audio quality, but certainly 'handy' in many applications) and 3-heads in a cassette deck (1973).
      In the late 1970's, Technics introduced what are some of the currently most sought after reel to reel decks out there. The Technics 1500 and 1700 series. They are overall 'amazing'!
I am a HUGE fan of Technics gear, especially their cassette decks. I worked for a Technics dealer in the early 1980's and loved to sell Technics gear because, not only did I know it would perform splendidly for most applications, it rarely came back with an issue. In fact, I extend that opinion to today, now 30 years on, as if I have to place a 'blind bet' on an 'as-found' item either still functioning, or being not far from it, I will go with Technics almost every time. Yamaha would typically be my second choice followed by the other 'famous' manufacturers a ways down the list. That's not to say 'Technics can do no wrong', because like everyone, they built a few 'lemons', but overall they do MOSTLY right.
