ü We have gone through this unit quite some time ago for ourselves to use, and just ran it through the shop again which involves disassembly of the transport, cleaning inside and out, DISASSEMBLING, cleaning and re-lubricating all internal mechanisms and the balance of efforts listed below (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 during original service

ü Counter belts replaced during original service

ü Idler tires replaced during original service

ü Idler tires reconditioned during this most recent service

ü All internal trim pots, switches and controls 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.

Total technician time to restore ~19++ HOURS! (YES, OUCH!)

This deck is the commensurate deck for other Marantz components such as the Marantz Escotec SC-7, SC-8, SC-9, SC-500 SC-2000 Pre-Amps, the SM-8, SM-500DC, SM-2000 Power Amps, EQ-20 Graphic Equalizer, PM-8, PM-450 or PM-730 Integrated amps, ST-500 Tuner and many others. I sold all of those components when they were new for a Marantz dealer. If you're building that system (or already have most of that system) and need the matching cassette deck (for Playback), then here you go. This one is probably as good as it's going to get, as I don't know of any tech's who would be willing to bring one any further to completion

   This is a very high quality control / pre-amplifier for most any system. If you need high level sonics, the Yamaha C-80 is the ticket. Will work with most any power amplifier, tube or solid state. After bench work the unit looks, performs and sounds great! Besides the fact that it's a Yamaha, this unit stands in a class by itself due the the "fully parametric" EQ and it's versatile "phono" section. Again, great where you need power amp control, with super pure tone routing. Unit measures 17" wide x 3.25" tall x 14.5" deep and weighs 7 lbs unpacked. Includes our standard 90 day limited  warranty.

BUFFET CLARINET
MODEL B12
INTERMEDIATE STUDENT Bb CLARINET
for sale
This clarinet is modeled after the Famous Buffet Grenadilla wood clarinets from the 'old day's'. When I worked for a 'full-line' music store thru the 1990's, we would periodically have a 'vintage' Buffet come thru and they never hung around long once serviced for re-sale. It is what most clarinet players asked for. That and Yamaha's.  This is a Buffet B12 clarinet, again, designed after the 'vintage' horns for the student / beginner and into the intermediate market. The Buffet B12 clarinets are made from ABS resin with an appearance and sound similar to that of genuine Grenadilla wood. These models are lightweight, strong and easy to clean perfect for even very young players. The Buffet B12 model has a very attractive and traditional design with nickel-plated body rings, straight key work and a traditional bell ring. The body is buffed to give the appearance of wood. The nickel silver key work is cold forged and induction ered, providing greater stability, precision and quality. The B12 model is mounted with double fish skin pads which ensure excellent sealing.

 Features:
- Nickel plated keys, body rings & plated bell rings
- 65mm barrel
- 14.65mm poly-cylindrical bore
- Arched key cups (same as R-13 model)
- Staggered trill keys (same as R-13 model)
- Blue Needle Springs
- Adjustable 3-position thumb rest
- Ergonomic key design: Improved playing comfort like that of a professional clarinet
- Pointed needle springs for quality key action
- Undercut tone holes for improved tone quality and faster response
- High quality Double fish skin pads enables air tightness and are long lasting
- Blow-molded, hard shell case

Mouthpiece Assembly with Ligature, Cap and Mouthpiece

-           Cork Grease

AND WHEN PURCHASED FROM OAK TREE VINTAGE WITH A NEW, DIAMOND CARTRIDGE NOW INCLUDED
NEW
for sale
Professional DJ / Club table. Quality tool for the 'long haul'! The Audio-Technica AT-LP1240-USB DJ turntable. Similar in design to some of the vintage turntable models, such as the Kenwood KD-550 'concrete base', the Sony PS-T1, and the Technics SL-1500, SL-1700MK2 or SL-D2 turntable models. This professional stereo turntable features a super high-torque, direct-drive motor for quick start-ups yet is perfectly quiet. Classic 'S' shaped tone arm with 'universal' head-shell that allows mounting of most any 'quality', 1/2' cartridge, either MM (moving magnet) or MC (moving coil). Tone-arm mounted in high quality 4-point, Gimbol bearing.

The AT-LP1240-USB plays back 33-1/3, 45 and 78 RPM records (78 is selected by pressing both 'speed' select buttons simultaneously). Its built-in phono preamp enables the turntable to be connected to a wide variety of music and home entertainment systems, powered speakers, and to A/V receivers that do not include a dedicated phono input (de-featable for 'old schooool' and 'REAL' receivers and integrated amplifiers that 'DO' have a built-in phono pre-amp. The turntable includes PC- and Mac-compatible Audacity® software that converts the audio on a record to MP3, WAV or other format digital audio files.

NEW UPDATE--- We're now including the Audio-Technica AT-95E, MM, Elliptically cut diamond cartridge with tables purchased from us at Oak Tree Vintage.

Table has great mass at almost 30 lbs!

Professional features for DJ use in nightclubs, touring & mobile applications:

- Direct drive high-torque motor
- Quartz Locked Speed Control System or 'Manual' Strobe Speed controls
*- Adjustable Braking Rate (0.2 – 6.0 seconds)
*- Adjustable Starting Rate (0.2 – 6.0 seconds)
*- Dual Platter / Motor 'Start' / 'Stop' controls
- Fully-Manual operation
- Selectable 33/45/78 RPM speeds (you will need to acquire a stylus / cartridge designed for playing '78 RPM' records to utilize that feature to it's fullest)
- Professional weight cast aluminum platter with slip mat (no PLASTIC platters here, unlike many of the NEW tables out there!)
- Classic 'S' style tone-arm
- High quality 4-point Gimbol bearing
- ½-inch mount universal head shell

- Internal Built-in Phono Pre-Amp of decent quality so if you MUST use this with some sort of 'home-theater-surround-sound-5.1, 7.2, or 8.BR549 receiver' that the manufacturer forgot to include the phono pre-amp on. If you have a 'REAL receiver', ie, an old-school, vintage, 2-channel receiver or integrated amp or pre-amp with a phono pre built-in, then you can flip a switch and bypass the 'built-in' phono preamp.
- USB output—connects directly to your computer for plug-&-play use
- Forward or reverse play (this is a DJ feature, and if you value your vinyl or cartridge, DON'T USE 'Reverse'! If you have a crappy cartridge and are playing 'Frisbees', then 'go for it' if you're so inclined!
- *Comes with Mac- and PC-compatible Audacity software and cables to digitize your LPs

VINTAGE NAD STEREO INTEGRATED AMPLIFIER
NAD 3120
STEREO INTEGRATED AMP
"STABLE DOWN TO 2 Ohms!!!"
#...1893
Circa 1984-86
 4/6/18
SHIPPED TO JEFF IN MICHIGAN

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

ü  Following both internal and external visual inspection, the entire unit was cleaned out including all contacts, switches and controls. Switches now clean sounding and performing fine.

ü Silicone heat sink compound inspected for ‘suppleness’

ü We adjusted / set the Output section bias / DC offset to BETTER THAN factory spec (check our results below).

ü All functions tested for perfect operation.

ü All inputs and functions tested.

ü Both amplifier sides produce clean and even sine waves! No power supply hum of any kind. It's dead silent!

ü Following electronic refurbishing, the entire unit was cosmetically detailed

ü Following restoration procedures, the unit was ran continuously at medium volume, as all our amplifier / receivers are, into a 4 Ohm load with "Loudness" on and both Tone Controls at 10 for 48 hours.

While this amp was originally rated at 25 WPC on our test bench the internal amplifiers of this particular unit, #...1893, produced 19 Volts per channel at 8 Ohms for 45 Watts per channel and  16 Volts at 4 Ohms for 64 Watts per channel via discrete, outputs (2x RCA 2N3055 & MJ2955)
Idle current draw .2A
DC offset, while the NAD 3120 service manual specs anything less than "50mV", and we originally measured this one, #...1893 at over 44mV / Channel, following our bench service it's now at only >2.0mV!!! on either side.
Very quiet with Floor noise measured at >-60dBm / 0.1 mVAC.
   ____________________________
   
Great performing and 'classic' looking NAD 3120 Integrated Amplifier. Essentially a more 'pure' version of it's predecessor, the 3120, in that they removed the 'tone control' circuit, and the LED power display.
Amazing sounding integrated power amplifier to provide the heart of a smaller to medium sized Hi-Fi system or 'project recording studio'. Unit looks, works and sounds great!

From the original Brochure,
"Designed for Real-World Performance: Specification tables and magazine test reports confirm that virtually all modern amplifiers measure well in the lab, with impressive figures for parameters such as the power output at 8 Ohms and the S/N with a shorted phono input.  But outside of the lab, amps are not all equal.
At home you don't listen to signal generators, short-circuits or 8-Ohm test resistor loads. you listen to complex and dynamic musical waveforms, generated by phono cartridges and reproduced through loudspeakers whose true impedance is rarely stable at only 8 Ohms.  So, rather than incorporating costly refinements that yield little or no audible benefit, NAD's "real world" approach to product design is focused on obtaining optimum performance under the conditions of everyday use....
Instead of the usual low-cost IC, the phono preamplifier section is a newly designed, discrete transistor circuit whose performance matches that of far more expensive preamp systems.  It interfaces correctly with the 'high impedance' of many magnetic pickup cartridges: it's RIAA equalization is precise: and it is virtually 'distortion-less'- not only with simple 'sine-wave' test tones, but also with dynamic, 'musical waveforms', 30dB above average level.  It's signal / noise ratio is close to the theoretical limit, not only with the short-circuit input that is often used for specifications, but also when a cartridge is connected.  It's total dynamic range is approximately 106dB."

NAD 3120 Features include:
  
- Discrete Output, Class A-B Amplifier design 
- Impedance selector for either 8 or 4 Ohms speakers, which means that you can get 100% of the potential power into just one pair of 8 Ohm speakers. (most amplifiers do not deliver more than 50 to 70% of their 'potential' power unless connected to a 4 Ohm load. This is BIG DEAL!)
- Pre-Out / Main-In loop
- I/O jacks and Speaker output posts feature 'Point to Point' wiring, so connections are 'stress free' on the circuit boards (all gear should be designed like this, but its 'too expensive' for most of the general public now
- 'Speaker / Tweeter Saving' "Soft Clipping" (defeatable if listener desires or to do 'bench testing')
- 'TRUE' Tape monitor (Tape Monitors can be used with Video / CD / DVD / VCR / DAT / MP3 / iPod® / iPad® / iPhone® / iTouch® / iGadget / MP3 / XM® / SIRUS® CDR (CD recorders as well as for inserting signal processors, such as EQ's, Reverbs, Spatial Enhancers / Dynamic Processors, Noise Reduction units, Special Effects units, Time Delays, etc)
- Phono / Turntable input
- 'Moving Coil' or 'Moving Magnet' cartridge selector (which means there is a 'head amp' for MC built-in. That alone is worth quite a lot of $$$)
- Tuner input (can also be used for ( Video / CD / DVD / VCR / DAT / MP3 / iPod® / iPhone® / iTouch® / iGadget / MP3 / XM® / SIRUS® etc. inputs)
- Loudness control. "Loudness" functions to boost Bass and Treble in relationship to Mid frequencies at lower volume levels for a much fuller sound
-  Heavy duty, 'Binding / Banana' post speaker outputs
- 1/4" stereo headphone jack
- Dual AC Convenience outlets (1 switched and 1 un-switched) with a total capacity of 250 Watts

Great integrated for just about any stereo system from smaller to medium sized speakers. As there's no tone controls, this would also make a great amplifier for a 'project / home recording studio'. This is a fabulous amp. Sonically superb following our techs work. Very musical. Lots of solid power / punch. Unit looks good and sounds great! Can include a pdf 'e' copy of the NAD 3120 Flyer and / or Service Manual if the new owner so desires. Measures 16.5" wide x 10.25" deep x 4" tall and weighs 12 lbs unpacked. Includes our 90 day limited warranty.

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

ü Following ext / int visual inspection entire unit was cleaned inside and out

ü All three 'control' PCB's removed to allow cleaning of ALL contacts, switches and control pots.

ü Bias adjusted to correct spec.

ü Switches and controls now clean sounding and performing solidly
(only exception is the 'High Filter'. It's 'lock' is a bit 'finicky' so if you want to 'bypass' the Hi-Filter, you need to engage it rather 'solidly' to get it to lock (stay in) ).

 ü All functions tested for perfect operation.

ü All inputs tested and both side produces clean and even sine waves!

ü No power supply hum of any kind. It's dead silent!

ü Following electronic refurb, entire unit was cosmetically detailed (It's BEAUTIFUL!!!).

This is first and only one Realistic SA-2000 we've had in 23 years. Classic brushed aluminum face plate with the original aluminum knobs.  Following 12+ hours of restoration procedures, the unit was ran continuously at medium volume, as all our amplifier / receivers are, into a 4 Ohm load with "Loudness" on and both Tone Controls at 10 for 48 hours.
Total technician time to restore 8 hours. (Tech noted on work sheet, "VERY nice build quality inside and out. Mint condition")
     
On our test bench the internal amplifiers of this particular unit, #...1087, produced 24 Volts per channel at 8 Ohms for 72 Watts per channel and 20 Volts at 4 Ohms for 100 Watts per channel via discrete, TO-3 / Metal Cased outputs (Toshiba 2SD426) (test at 1kHz, single channel at a time).
Idle current draw 0.425A.
Very quiet with Floor noise measured at >00.0 mVAC /->60dBm.
    ____________________________
 
Probably the best Integrated amp Realistic ever did (certainly was up until 1977, and after 1980, who cares). This is a great looking unit, with a classy 'Champaign' color, brushed aluminum face, and a 'REAL' wood veneer bonnet.
Just the right features & sonically magnificent! Great amp for home or project recording studio use.

SOLD 11/12/18
SHIPPING TO WILLIAM IN MARYLAND
These are from an upper-end line of speakers that Technics produced for MCS. The "Linear Motion" line used a Tri-Planer baffle board design to more correctly "time align" the 'top end' drivers with the woofer. The Midrange is on a 'spacer' to position it (time-wise) between the tweeter and woofer. This design was based on the Flagship (and very expensive) Technics SB-7070 speakers.
Our speaker tech has completely gone through and 'Certified' these. We have completely tested them with both recorded material, PN 20-20k and swept them with our AF generator.  
MCS 8320 Features include:

- 3-Way, Bass Reflex cabinet
- 'Time-Aligned' / Bi-planar baffle board
- 2" Pulp-cone tweeter
- 4" Pulp-cone Midrange
- 12" Ribbed, Pulp-Woofer with non-deteriorating Cloth surround
- 2.25" tuned port for extending low end
- External, resettable protection relays for all drivers
- 'Spring Clip' Speaker terminals

MCS 8320 Specifications / Specs:

Frequency Response: 32-22,000Hz +- 3dB
Efficiency: ~92dB 1W@ 1m
Nominal Impedance: 8Ω nominal
Recommended Minimum Power amplifier rating: 15 Watts minimum

Again, all drivers tested, work and sound fine! Tested for all frequencies with a sweep generator. Speakers cleaned inside and out. They have black cloth grills and the cabinets are a mixture of black and walnut grain vinyl wrapped. Cabinets and grills are in great shape. Grills still have all locating pins intact and frames are free of breaks / cracks etc. Each cabinet measures 24" tall x 13.5" wide x 12.25" deep and weighs 26 lbs unpacked. Includes our standard 90 day limited warranty ( & excluding problems due to under / over powering)

YAMAHA NS-A738 / NSA738 BIRCH FINISH
 #...4631 / 4632 (consecutive numbers)
Circa 1999-2000
Made in the USA (yes, really)
SOLD 12/26/18
SHIPPING TO JIM IN LOUISIANA
Great looking, performing and sounding Yamaha NS-A738 3-way speakers have a room filling, "tight" sound that ensures sonic accuracy. Great for home use or project studio monitors. If you can't afford the famous Yamaha NS-10's (now, currently north of $1000.00), then these may be an affordable alternative for your project recording studio (I used to be a dealer for NS-10's and have heard and sold many).


Our speaker tech has completely gone through and 'Certified' these.
We have completely tested them with both recorded material, PN 20-20k and swept them with our AF generator. Prior to testing with the sweep generator, we added gasket material under all the driver flanges in each cabinet to eliminate resonate vibrations. This is really a 'finishing touch' on this model of Yamaha's that should have been done at the factory, but is rarely done by most companies / manufacturers. We also added 'poly-spun' batting to the cabinet space to further tighten up the low-end, eliminate hollowness / cabinet ringing. Again, should have been done at the factory, instead of relying an 'empty cab' to allow 'boomy bass' which on the original sales floor, made the box appear sonically 'larger' than it is by making the box seem to be producing more bass. The 'bass' that an un-damped cabinet produces is 'hollow and flappy', and not what you'll want to listen to over the long haul. That would be come very fatiguing soon.
Handles power decently and reproduced the low-end in our most difficult test CD! If you've read some of our other 'audition notes', you'll know what is meant when I say that these speakers, "reproduced the "TLC 'Sub-Bass' note' VERY well" when situated on the floor.

 Yamaha NS-A738 Features include:
   
- 3-Way, Acoustic Suspension design for studio monitoring "tight bass"
- 8” High-Compliance, Cloth Surround, Polypropylene Coated, Long-Throw woofer, woofer w/ non-deteriorating cloth surround
- 4” mid non-deteriorating paper surround
- .75” Ferro-Fluid Cooled, Mylar, Dome tweeter
- Infinite baffle for exceptionally tight bass
  
Yamaha NS-A738 Specifications:
  
Frequency Response: 90-20,000Hz ± 3.5dB  
Efficiency: 91dB 1W @ 1m
Nominal Impedance: 8Ω each
Cross-over frequencies: at 4.2kHz & 13.5kHz (6dB / Octave)
Recommended Minimum Amp Size: 10 Watts
Maximum input power rating: 140 Watts
  
All drivers work and sound fine! Tested for all frequencies with a sweep generator and test CD's. Each finished in black, matte, vinyl wrap. Speakers look and sound GREAT!

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.

ü Internal 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 Capstan motor spindle bushing re-lubed

ü Capstan burnished

ü Main Drive and Counter belts reconditioned or replaced w/ new as necessary throughout entire transport for trouble-free service.

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

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 'Silicone Damped' 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 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 adjustment, records AMAZINGLY well w/ following results;

Recording Results following refurb / service, DECK 1;
ü Side A: 1kHz recorded @ 0dB with Dolby C engaged on Maxell XL-II (High bias) tapes plays back @ avg of -1dB L & R
ü Side B: 1kHz recorded @ 0dB with Dolby C engaged on Maxell XL-II (High bias) tapes plays back @ avg of -2dB L & R

Recording Results following refurb / service, DECK 2;

White noise was down ~ 2dB recorded at -5dB and -0dB recorded at -10 on Deck 2

ü 'DDD' CD recorded at 0dB with Dolby engaged; 0 to -2dB 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)

ü Cosmetically, the deck looks near new. Just a few scratches on the rear, sheet metal panel.
Total technician time to restore 8.5+ HOURS!
____________________________

Plays perfectly and after adjustment, records well at -0dB! (and we really put them through the paces, testing both with well mixed, recently recorded CD material and CD recorded / factory test tones looking for correct head Azimuth and speed accuracy). Pinch roller and heads all in GREAT condition!!! Both level meters playback even.  Speed adjusted to 100% accuracy with 1kHz factory test tape meaning that our 1kHz test tone tape, plays back at 1kHz* on BOTH WELLS and BOTH SPEEDS! Deck looks like NEW, works and sounds great! 
* 1kHz with pitch control centered!
____________________________

We commonly will not give a "dubbing" / dual well cassette deck a second look as there weren't many that were not simply two cheap decks in one box. I KNOW, as I have sold hundreds of them when new by just about every brand. I always tried to persuade anyone looking for a "real" deck, to generally avoid them and just get a good, single play deck or two single play decks. "Dubbing" decks, as a general rule just didn't have quality transports or decent specs. There were, however a handful of exceptions that combined the convenience of a dubbing deck, with quality and we have posted a few with our high quality single well decks! This Teac W-6000R is one of those few! It's super quality in design and build, and it's loaded.  This is an incredible deck for performance and IT'S LOADED! It would be at home in any audiophile system as well as pro / project studio. This was the top of the "W" series of Teac's and had an original MSRP of $750.00!

TEAC W-6000R Features Include:
 
- HX-PRO (Extended Head-Room Recording)
- GEAR DRIVEN reels (This is BIG on a cassette deck. Much of the issues with 'tape eating' and fast wind issues can be attributed to 'idler tire issues' on cassette decks, and most use them. This deck utilizes 'gears' so no tires to glaze, crack or otherwise deteriorate over time. Taking that off the table, means the deck will likely last many years / decades over other decks)
- Dual-well design with both decks being essentially identical internally and BOTH WELLS RECORD!
- Dolby B & C Noise Reduction built-in
- Pitch Control on deck well "A", allows adjusting to "pitch" for musicians +-12%
- A+B / Parallel Record. This means that both decks record. This allows you to make two "master" tapes at the same time. Only a small percentage of dubbing decks will do this!
- "CD Sync" allows continuous recording / playback through both decks
- IC Logic "touch-control" tape transport on both decks
- Super-quality tape heads
- Dual Well "Quick" Auto Reverse. ("Quick" Auto Reverse, meaning that it senses the beginning of the tape leader instead of switching at the end of the leader due to tension)
- Tri-Mode transports; One way stop, U-Turn Auto-Reverse, Infinite Loop Auto-Reverse
- CPS (Computomatic Program Search) Function. Allows selection and playback of any tune up to 15x ahead or back
- Both Normal and High (2X) speed dubbing
- Auto-Selector for Normal, CrO2 & Metal Tape Type
- Full fluorescent readout screen
- Dual fluorescent signal level meters with peak hold that are shared and can be utilized with either tape well.
- Dual Digital tape counters can be selected for either tape well, and can be independently memorized / reset for each well.
- "ARLS" Automatic Record Level Sensor for either tape well, 1 or 2
- "Tape Mix" control allows a "mix" of signals from any combination of the Tape in well "1", Microphones, and a Line-In signal to be recorded onto Tape well "2"
- Record Level controls for either tape well, 1 or 2
- Record Balance control for either tape well, 1 or 2
- Record Mute function on both wells
- Timer Play / Record / Off selector
- Dual 1/4" mic input jacks
- Independent L & R Microphone input level controls

 This TEAC W-6000R would be perfect for the project studio as a mastering deck or home audio system use. Especially for a "project studio" as the "Tape Mix" control practically turns it into an "all in one" studio. It allows a mix in any combination of a tape in well "1", the microphones and a Line-In signal to be recorded onto a tape in well "2". Also great for transferring your tape collection to CD, Hard-drive or MP3.  Built very well! Looks like new and sounds great. Deck includes a copy of original Teac W-6000R owners manual. Measures  17.25" wide x 13" deep x 6" tall and weighs 15 lbs unpacked. Comes with our 90 day limited warranty.

ü Our technician has completely and EXTENSIVELY gone through and 'Certified' this unit which involves complete removal and disassembly of the entire 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 Capstan motor spindle bushing re-lubed

ü Capstan burnished

ü Internal 23VDC power supply tested to 23.2Volts

ü 2X NEW, Custom made, 'reel drive' tires installed for years of 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 new internal Drive and Counter 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 Entire flywheel assemblies re-lubed upon re-assembly

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 'Silicone Damped' Eject door operates smoothly.

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.

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, the deck and the 'wood grain wrapped' case / cabinet looks NEAR NEW!

ü Plays great and after adjustment, records AMAZINGLY well w/ following results;
With Pink Noise recorded at 0dB w/o Dolby engaged; -2dB on Maxell UDXL-II / High Bias tapes
With 1kHz recorded at 0dB with Dolby engaged; -0.3dB on Maxell UR (normal bias) tapes
With 'ddd' CD recorded at 0dB with Dolby engaged; -2dB on Maxell UDXL-II / High Bias tapes
With 'ddd' CD recorded at 0dB with Dolby engaged; -1.5dB on Maxell UR (normal bias) tapes
With 'ddd' CD recorded at 0dB w/oDolby engaged; -3dB on Maxell UR (normal 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 10+ HOURS!

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 like new, works perfectly 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 incase you 'too casually' read past that last little bit,
IT'S A TWENTY-SIX POUND CASSETTE DECK!
Includes our standard 90 day limited warranty.

for sale
Pre-Recorded, 1/4" X 7" (18cm), Realistic / Radio Shack, 'CONCERTape', 1800 ft reel to reel tape.
Great tape for general purpose recording.
These are 1800' / 548.6 meters and 1.0 MIL thick, and include individual, boxes with a plastic reel. More than enough length for most LP's at 7.5ips (fast, consumer speed) for 90 minutes combined sides (180 minutes at 3.75ips). According to an original catalog, "1-Mil base of heavy-duty Polyester resists breaking and stretching while giving you extra-wide response.""   Will work on any 'head format', meaning 'quarter track', 'half-track', 'full-track', '4-track / '8-track' / 'multi-track', stereo or mono tape recorders / decks. Reels are 'light gray' plastic. Leaderless tape.
We have actually found that 'Normal' bias tape works best on the older decks such as the pre 1980 Akai's, Concertone's, Craigs, Crowns, Grundigs, Kenwoods, Pioneers, Realistics, Sansui's, Sony TC's, Tandbergs, Teacs, Telefunkens, etc. We have gotten some fine recordings using this tape, and due to the extreme 'retention' of high bias tape some times it is difficult to erase. These always seem to erase fine.
 Most are at least 1800 feet and some with leaders intact and may or may not include individual box (often do). Most have been used and will have recordings on them. Boxes and / or reels may have extraneous labels and / or marking on them. Reels may have blemishes / nicotine staining / dust etc. You will need to come up with your own labels as even if they are in the box, they likely aren't "sticky" anymore. Due to unpredictability of stocks we cannot "cherry pick" brands so they are always assorted. Plastic reels may be clear or black. Will work on any 'head format', meaning 'quarter track', 'half-track', 'full-track', '4-track / '8-track' / 'multi-track', stereo or mono tape recorders / decks. Use a bulk eraser or will simply erase when new recordings are made on your deck (assuming your 'erase' is functioning).
