This is a BEAUTIFUL, brushed Pewter face deck with complimenting brushed, Silver knobs. The Sony TC-K8B, Stereo Cassette Tape Deck w/ F&F heads, IC logic,
Liquid Crystal meters, and Dolby NR. This was one of the first units to utilize 'Liquid Crystal', and they are quite unique looking to most of the examples that followed. This was Sony's top of the line units at the time and retailed for $850.00 in 1978 which is equivalent to over $3,200.00 today!!! That should give you an idea of the stature of this deck for it's time.

Sony TC-K8B Features include:
  

- Super Hard, 'Ferrite & Ferrite' heads (we've had a number of Sony Reel to Reel decks with these and they never seem to wear out)
- IC logic "touch-control" tape transport with motor driven 'cam control mechanism'
- FG Servo Capstan Motor
- Dolby-B noise reduction built-in for recording and playback
- 3-Position Tape Bias Type / EQ selector for Normal, Fe-CO2, CrO2 & Metal tape
- Peak LED indicator and 'Peak Hold' function

- Very cool, Liquid Crystal VU signal level meters
- Manual Record Level with independent L&R control
- Variable Output Level control (one of the most important features on a deck in our opinion)
- Record 'Mute' function

- Dual front mounted 1/4" mic input jacks
- Front mounted Stereo Headphone jack
- Front mounted Stereo, 1/4" line-in jack (as well as standard, rear mounted RCA connectors)
- Analog Tape Counter
- Selectable 'Memory' point
- Rear mounted, 11-pin port for optional Sony, RM-30 'wired' remote control (not available from us)
- 3-Prong, Grounded AC cord. (first cassette deck we've ever had with a 'grounded AC circuit')
- True "WORLD AC POWER"™ allows unit to be operated on 50 or 60 Hz AC and will select voltages from 110V, 120V, 220V and 240 Volts AC input. (this is one of the few cassette tape decks that we've ever had, and the ONLY one now that allows both 60Hz and 50Hz operation)

Again, we have completely refurbished and thoroughly tested this deck, with multiple recording tests (as stated previously it took 16+ hours of tech time to do it proper justice). This is a VERY handsome deck (the photos can't do it justice). Cosmetically, it's in excellent condition! About the only items worth mentioning is slight wear to some of the silk screened lettering, primarily near the 'Peak Hold' selectors, some light scratches to the left, side panel of the sheet metal housing and some 'spots / splotching' to a couple areas of the face (we weren't able to remove by any of our normal means. See photos above).
Great deck for just about any system. Also great for transferring your tape collection to CD, Hard-drive or MP3.
Measures 17" wide x 12.25" deep x 6.75" 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!

Comes with our 90 day limited warranty.

ü
Cosmetics are not great, with numerous 'battle scars', but makes up for that in performance.

ü Plays perfectly and after adjustment, records AMAZINGLY well at 0dB! on Maxell UDXL-II tapes and +1dB on Maxell UR / Normal Bias tapes. (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 TDK and "Maxells" performed VERY 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 14+ HOURS

Again, we have completely cleaned, refurbished / serviced and thoroughly tested this TASCAM 112R cassette tape deck.

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 Capstan burnished

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)

The Teac A-510 / A-500 with 'Dolby NR and IC Logic Transport', 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. Very impressive looking deck.

Teac A-510 Features include:
  

-  "Soft touch / IC LOGIC 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 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)

Again, as mentioned above, our tech has gone through it completely cleaning all parts, controls and tape mechanism. As mentioned, the power supply was originally not functioning correctly, so before restoration could commence, we replaced a faulty voltage regulator.
We also checked, cleaned, reconditioned and / or replaced rubber components. We completely de-magnetized the heads and transport. Capstan motor speed adjusted to exact spec! Tape speed re-adjusted to 100% accuracy, ie; 1 kHz = 1 kHz! And with it's service work completed the deck records incredibly well and plays back utilizing Maxell UD XL-II tapes at 0dB down! About the only cosmetic issue worth mentioning, is that there are some scratches to the black paint, on the top sheet metal housing. Probably from someone setting a unit on top of it that didn't have feet. Of course you only notice that when looking 'down from above' the deck, so in a rack, wouldn't be seen. Overall, the deck looks good and sounds great! Great for transferring your tape collection to CD, Hard-drive or MP3. Plays and Records extremely well. Very clean and usable deck! Includes a pdf / e-copy download of the Nakamichi BX-2 owners / users / instruction manual. Measures 17" w X 10" d X 4.25" h and unpacked weight is 13 lbs. Comes with our 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. 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. 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’.

          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’.

    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 complete 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 All drive tires reconditioned for trouble-free service.

ü All new internal rubber belts replaced for trouble-free service. (a note about the 'belt kits' out there. We were out of a couple of the belts we needed, so to make it easy / quick, we thought we'd order a 'belt kit' from an ebay seller (yes, we should know better). We installed them, and went on with the restoration. At the first opportunity to do some testing during it's 'bench time', we noticed 'fast' WOW / 'slow' Flutter when recording test tones (especially prevalent with recording, then playing back 'Piano' music). After spending 'hours' trying to track down the issues, and in the interim we had 're-stocked' our normal belts, changed out the ebay purchased ones for our 'stock' units, and the problem was solved. That seller was selling 'round' belts ("round belts" typically shouldn't be an issue), but the Marantz 5220 deck MUST have 'Square' belts. Just FYI (at our expense).)

ü Rubber pinch roller reconditioned

ü Capstan burnished

ü Missing Capstan thrust screw replaced

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 All internal light bulbs changed

ü All internal 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 and head alignment / azimuth has been checked for peak performance.

ü Both Internal playback amplifier channels adjusted for 'even output'

ü Meters adjusted to even zero with symmetric input.

ü Both Internal Record amplifier channels adjusted for 'even output'

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

ü Playback meters zero with factory test tone tape.

ü Tape Counter and 'Memory' Function tested

ü Plays perfectly and records well @ ~0dB (with Maxell UDXL-II tapes @ 1kHz) and @ ~-2.5dB (with TDK D tapes with Pink Noise)( 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!!! -Both level meters playback even.

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

Face is made of beautiful brushed aluminum, and overall the deck is in fabulous 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 TDK 'D' / Normal Bias tape performed the best on this particular deck.
 Total technician time to restore ~16 HOURS! (12 Hours Tech time, then another 3-4 hours testing / evaluating)
  ____________________________
  
From Marantz's Classic and always sought after, 'Blue Face' years. This is the first of Marantz cassette deck from this series that we've had make it through our process in over 21 years, and it was a 'long journey'. Marantz only made 3 'vertical' models of cassette decks, with the 'Smoked Plexi' look. The 5020 (lesser model), the 5200 (same as this deck, but without Dolby), and this 'Top of the Line' 2-Track, 5220! Mid-70's cassette deck with classic, Piano-Key transport operation, Dolby, stereo cassette tape deck. Great deck to add to your classic, brushed silver and 'Blue Face' Marantz 'stack or rack'.


Marantz 5220 Features include:
  

- Super Hard, 'Ferrite' heads
- Classic 'Piano Key' transport operation
- 4-Input Channel 'Mixing' capability (Allows both Microphone inputs and both 'Line Level' inputs to be mixed ALL AT ONCE to tape, or simply out to your speakers)

- MPX Filter, for eliminating the 19kHz 'pilot' signal from FM broadcasts. You can use this while recording, or as a ' Listening filter all the time' by putting the deck into 'Record Pause'. (located on rear panel)
- FM Deemphasis for either 'Flat' or 25μSec

- Separate, L&R, Variable
Play / FM Calibration (for utilizing this deck as an external 'Dolby' processor for another deck that is lacking Dolby)

SOLD TO RYAN IN VIRGINIA


ü Our technician has completely and EXTENSIVELY gone through and 'Certified' this unit which involves complete removal and disassembly of the entire tape transport, cleaning inside and out, DISASSEMBLING, cleaning and re-lubricating all internal mechanisms and the balance of efforts listed below (unit actually worked very well prior to disassembly as well).

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

ü All new internal Capstan Drive belts replaced for trouble-free service.

ü New 'Shift Roller' acquired (from Slovikia) and installed.

ü Left Rubber pinch roller has been reconditioned

ü Capstan 'Thrust Bearings' cleaned and re-lubed w/ silicone based lube

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

ü Head alignments and azimuth at 125Hz, 1kHz and 10kHz adjusted for 'peak performance' with O-Scope. Both channels now even w/ 'max' output.

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 'Auto mechanism' operates smoothly.

ü Tape Counter Function tested

ü Dolby B & C NR circuits / function tested

ü HX-Pro tested

ü 'Memory / Zero Return' function tested

ü Heads are in great condition

ü Meters adjusted to even zero with symmetric input.

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

ü Both Internal playback amplifier channels adjusted for 'even output'

ü Meters adjusted to even zero with symmetric input.

ü Both Internal Record amplifier channels adjusted for 'even output'

ü Playback meters zero with factory test tone tape.

ü Speed tests at 100% accuracy (this deck has a 'FG-Servo / Synchronous' motor with a circuit board mounted, 'Comparator' system to maintain perfect speed so is 'always' 'on speed'), with 1kHz factory calibration tape (meaning 1kHz calibration tape plays back at 1000Hz +/- 1Hz)

ü
Cosmetics are not great. The sheet metal case has some creases / dents (don't know how they got there), and the originally, optional Rose wood side panels have a few dents (don't know if they were there before someone acquired them, or happened after installation). The wood panels could be removed, and we thought about it, but even with their cosmetic issues, they add to it's overall look being left intact.
ü Plays perfectly and after adjustment, records AMAZINGLY well. Normally we would give a "dB Down or UP" rating / results, but this deck has so many ways to have it's record levels and quality 'tweaked' that there's no 'one number' that can be assigned to it. Yes it can record at 'positive dB's' but with different attributes depending on the tape type and how 'hot' you wish to record. We found the best results with at Maxell UDXL-II tapes. We tried recordings using the 'Calibration' system, but usually found that we liked adjusting the 'Bias' control to suit our ears. Then we discovered the +/-3dB 'Record Level' control (No not the typical "Input Level" control, that is always labeled "Record Level", but a control on the outside that gives you access to the actual 'internal "record level"' normally located on the circuit board and adjustable by a technician via 'pc mounted' pots. This opened up a whole new layer of recording that we normally only get to experiment with while a unit is on the bench.
While doing the test recording's, it became apparent that this decks recording capabilities were AMAZING.

Total technician time to restore 8+ hours.

____________________________

The Sony TC-K850ES, 3-Head / 3-Motor Cassette Tape Deck. Great deck for doing your tape transfers if your tapes were recorded with no NR or with "Dolby B" or "Dolby C", but REALLY SHINES if you want to make new tapes as it's got HX-PRO and 'TONS' of serious recording features. Again, as stated above, records AMAZINGLY well! Also has 'gear driven' reel tables, which means there not 'pesky' idler tire or drive belts to worry about (which takes 'eating tapes' off the table).

SONY TC-K850ES Features include:
  

- 3 Heads (allows instantaneous monitoring of recordings for the best audio results)
- "Laseramorphous Magnetic Alloy" head (wow, that's a mouthful, but means that it's got a super accurately cut gap, and is of a 'really hard, non-magnetic material, which thus means, "it sounds good now and will for a long time")
-
*User adjustable RECORD LEVEL control (+/- 3dB, and NO, NOT the same as the typical 'Input (record) Level Control'
- User adjustable BIAS control
- Tape 'Calibration' system
- HX-PRO (HX-PRO is used to 'encode' your tapes as you record. Once a tape is encoded in HX Pro, it will playback on any deck, then exhibiting the benefits of HX-Pro)
- FG Capstan motor with 'Quartz Locked' speed (never needs adjusting and will always be 'speed accurate')
- 'Closed Loop / Dual Capstan' tape transport system

- 3 Motors
- IC logic "touch-control" tape transport
- Motor driven Tape Load and Eject
- Auto Selector for Normal (EX / I), CrO2 (SX / II) & Metal (ZX / IV)Tape Type
- Multi-Functional Fluorescent display window

- Digital, tape counter
- Dolby B&C NR
- Record Muting
- "CD DIRECT" input (bypasses MPX filter, Balance and likely other circuits)
- Built-in MPX filter for killing the 19kHz pilot tone in FM transmissions
- Input level control with L & R balance (balance control sometimes has best meter balance at somewhere between "11:00 and 1:00" depending on tape type and / or Biasing position and  / or 'Record Level' position)
- Memory Stop / Repeat for counter

- AMS (Automatic Music Sensor) system for finding next or previous tracks (must have a min of 4 seconds between tracks / songs)
- Front mounted, 1/4", Stereo Headphone jack
- Timer Play / Record function.

Again, we have completely cleaned, refurbished / serviced and thoroughly tested this SONY TC-K850ES cassette tape deck.
It does have a few 'battle scars' (see above photos), but will make up for it in performance, again check the recording results, and the 1kHz = 1kHz speed!
If I didn't already have 'a sufficient number' of cassette decks in my collection, this one wouldn't be leaving, especially after experimenting with the 'Bias and Record Level' controls.
Great for transferring your no NR or Dolby B / C NR / HX-PRO encoded tape collection to CD, Hard-drive or MP3, or BETTER YET, 'making your own tapes' with HX-PRO. Built very well! Looks like new, works and sounds great.
Comes with an 'e-copy' / pdf of the Sony TC-K850ES owners manual and the service manual if purchaser desires. Measures 18.25" wide (w/ wood panels installed) x 13.5" deep x 5.2" tall and weighs 16 lbs unpacked. Includes our standard 90 day limited warranty.

ü Our technician has completely and EXTENSIVELY gone through and 'Certified' this unit which involves complete removal and partial 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).

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

ü 'Gear driven' hubs, so NO reel tires for trouble-free service.

ü Main drive / capstan belt replaced for years of trouble-free service.

ü Rubber pinch roller has been reconditioned

ü Capstan burnished

ü Heads have been cleaned and de-magnetized as well as the entire transport. (Tech noted, "VERY minimal wear" to the heads on the work sheet)

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

ü All 'user' potentiometers / controls removed, then cleaned and tested for noise-free function.

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

ü Both spindles in perfect alignment.

ü Cosmetics are decently clean, with typical, minor wear

ü Floor noise measured at -60dBm

ü Plays perfectly and after adjustment, records very well at -0.5 to -1dB! on most formulations of tape however, two did 'shine' over the rest of our test tapes. We did 'test recordings' of Pink Noise and 'ddd' CD's 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 they all performed VERY well on this particular deck (although the Fuji DR-1 definitely came up 'last'). The Sony HF 'Normal Bias' did very well with both PN and ddd CD at -.5dB w/ no NR. It exhibited good saturation capabilities with minimal 'high end' loss. It recorded at -6dB w/ dbx engaged, but that was from a starting point of more than +10dB on the meters. Dolby B was -2 and C was -2. Maxell UDXL-II was at -1.5dB with PN, but with ddd CD and no NR it exhibited great recording at -1.0dB with GREAT high end retention. dbx was at -6dB down, but again, that was from a ++10dB starting point. Bottom line is it makes GREAT recordings.
Total technician time to restore 8+ HOURS!

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

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 16.5 HOURS!

Again, we have completely cleaned, refurbished / serviced and thoroughly tested this TASCAM 112R cassette tape deck.
It does have a few 'battle scars', so isn't going to 'win' any beauty contests (
see above 'horizontal' photo collage), but will make up for it in performance, again check the -1dB recording results, and the 1kHz = 1kHz speed!
Great for transferring your no NR or Dolby B / C NR encoded tape collection to CD, Hard-drive or MP3. Built very well! Looks like new, works and sounds great.
Measures 19.25" wide (w/ rack ears installed) x 11.5" deep x 4.6" tall and weighs 13 lbs unpacked. Includes our standard 90 day limited warranty.

ü Our technician has completely and EXTENSIVELY gone through and 'Certified' this unit which involves complete removal and partial 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).

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

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

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

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

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 'Memory / Zero Return' function tested

ü Cosmetics are LIKE NEW!

ü Plays perfectly and after adjustment, records very well at -1dB! on about any formulation of tape. We did 'test recordings' of Pink Noise and 'ddd' CD's 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 they all performed VERY well on this particular deck. We did however find that the deck likes to record at about -10dB on the meters, for 'smoother saturation' of tape. 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 8+ HOURS!

- IC Logic, 'Silent Mechanism' Tape Transport controls
- 2 Motor Transport
- Dolby B & C Noise Reduction

- Tape type selector for Normal / Chrome & Metal tapes
- Fine Bias Tuning (really becomes useful coupled with the "3-head" design for 'fine tuning' recordings around different tape types)

- 'One Touch' Rec/Pause

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.
