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

ü We have completely gone through this unit cleaning everything including all switches, controls and contacts. VERY time consuming to properly service this unit, especially the 8-track deck. Extensive cleaning of unit internally.

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

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

ü Entire transport was disassembled down to the chassis, and every mechanical part was cleaned of "varnished" lubes and re-lubed as well as the always at issue, Pinch Roller plunge assembly, re-lubed and reassembled (VERY DIFFICULT and TIME CONSUMING on this unit)

ü Main drive belt has been replaced with NEW for trouble free service (#42-480).

ü Replaced bad track indicator lamps, and checked the balance for function

ü Capstan flywheel removed, cleaned, burnished and re-lubed prior to re-install. Entire transport and mechanism has been cleaned, re-lubed and de-magnetized.

ü Program change mechanism and indicator contacts cleaned / burnished and re-lubed for trouble-free program changes. All original program indicator lamps now work fine.

ü Heads have been cleaned and de-magnetized and are in great shape.

ü Head azimuth & track cross-talk adjusted for optimum performance and the best high-frequency response (not normally expected from 8-track cartridge performance) utilizing RCA #356 and 8TSC-101, Aspen 'Deck Tester' and Audio-Tex 30-312 Test / Alignment tapes, a dual trace Oscilloscope and frequency counter.

ü Track alignment adjusted to eliminate 'cross-talk' between tracks and to ensure the best high-frequency response (not normally expected from 8-track cartridge performance) utilizing RCA #356 and 8TSC-101, Aspen 'Deck Tester' and Audio-Tex 30-312 Test / Alignment tapes, a dual trace Oscilloscope and frequency counter as well as our 'best' pre-recorded tapes.  Deck now has clear sounding highs even when using pre-recorded tapes.

ü Record signal path contacts cleaned and burnished for static-free performance

ü Linear Record switch cleaned so no 'Motor Boating' effect

 ü Internal playback, meter and record level pots also adjusted w/ O-scope.

ü Following refurbishment, Speed checked with factory test tape to 98.5% accuracy! (meaning in this case, that our 1000Hz test tape plays back at 985Hz on our Freq Counter Meter)

ü Deck 'sonically' checked for WOW and Flutter with no appreciable issues

ü Record Meters adjusted for 'even' readout and performance

ü Floor noise tested @ -60dBm

ü Since we also burnished the program track light contacts, they all light and are responsive. Unit works and sounds GREAT!

ü Tuner string checked for any fraying then re-tensioned to increase traction & relieve flywheel binding and re-centered pointer to correct dial position.

ü We aligned the tuner front-end for optimum AM & FM performance as older internal tuner components have always drifted on vintage gear over the years. VERY GOOD TUNER! AM seems to be an 'afterthought' on many stereo receivers and component tuners. The AM is above average for a 'stereo receiver' on this Panasonic RA-6800. 

ü All dial, indicator & meter lamps work or were replaced.

ü Stereo indicator lamp replaced (even though original was working)

ü We also checked the heat sink compound which should be good for another 30 years.

ü All inputs tested and both side produces clean and even sine waves into 'brick-wall' 8 & 4 ohm loads! No power supply hum of any kind. It's dead silent! All functions test fine.
Total restoration time investment 7 hours.

ü Following restoration procedures, the unit was run continuously at medium volume, as all our amplifier / receivers are, into a load with "Loudness" on and both Tone Controls at 10 for 72 hours into a 4 ohm load.
  
Mechanically the only issue worth mentioning is that that due to a cracked gear, common to about 50% of the 8-tracks out there, the tape counter was 'defeated'. About the only cosmetic issue worth mentioning is that I'm pretty sure the plexi dial window was less yellow when new.

On our test bench, each internal amplifier of this particular unit, #...0181, produced peak power of 16 Volts per channel for 28 Watts per channel @ 8 ohm and 13 Volts @ 4 ohm for 42 Watts per channel @ 1khz from actual discrete output transistors (2x 2SA1060 and 2x 2SC2484) (ALL the other 'compacts' we were working on utilized STK power pack, which had some to do with why we couldn't resurrect many of them. The DC was just too high in many cases, and couldn't be rectified practically). AC Idle current at <.35A, & floor noise -60dBm. DC offset checked to <30mVDC / channel (VERY good for a 'compact' unit).
  ____________________________
  
So, as with anything you want to look up on the 'world wide interweb', you will find a myriad of opinions. Many of them are from folks who have never even personally experienced what they are 'spouting off' about. Well, of course, I have mine too, however, mine will be from someone who does have 'personal experience' with whatever I'm 'expounding' about, and is from 'real world' experiences, 'down in the trenches'. I often get a 'kick' out of what folks have to say (generally negative) about a piece of gear, with no actual, personal experience. Recently read so many opinions of a speaker we had just finished and were about to audition, prior to auditioning them, that I was not holding out much hope for their final performance. Not only was I surprised by their actual performance (in a positive way), they were completely the antithesis of what EVERY opinion on the web stated, with NONE of them ever actually hearing them (they all stated so in their opinions). Anyway, I'll climb down from my 'ivory tower' for a moment just to say that for what this is designed to be it really came out as a wonderful unit following it's 18+ hours of service to bring it back to essentially 'new' condition. Wonderful condition, and for a 'compact system' REALLY GREAT SOUNDING, late 70's, silver face 'Combo' Receiver from Marantz. We've had this for years, but just recently got around to restoring it. We had a few 'compacts' from brands such as Sony, Panasonic, Fisher, Marantz, but most did not pan out (didn't even attempt the 'cheeeeeese' from companies like Electrophonic, GE, Lloyds, Symphonic and a host of other 'bottom feeder' units.

It really is surprising in sonics, performance, feel and quality. Great performance for a 'small to mid-sized' 2-Channel audio system. This is the first 'compact' we have 'pass muster' in the past couple decades (I think the last one was about 1998 or 99 and shipped to Germany).
This is an INCREDIBLY ‘Musical’ sounding receiver. Lot's of surprising 'punch' and volume. It's also one of the best sounding 8-track decks we've auditioned (following restoration). Playback of 'quality' tapes is punch, balanced and bright (typically fairly un-common on 8-track decks). Recording is decent as well, but the playback quality is fabulous. Probably one of the top 2 or 3 decks we've ever had for playback sonics.
Yes, I know, it's a 'compact' and not a 'separate component', but it really is that nice!!! Enough power for up to 'medium-large' / 10" woofer speakers.

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 soldered, 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

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-1600MK2 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 Starting Rate (0.2 – 6.0 seconds)
*- Dual Platter / Motor 'Start' / 'Stop' controls
- Fully-Manual operation

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!

SOLD 5/3/18
SHIPPED TO MASSACHUSETTS

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

ü Following ext / int visual inspection entire unit was cleaned inside and out including all contacts, switches and controls.

ü One side rebuilt by 'old school' tech

ü Heat sink compound upgraded to Silicone Pads

ü Bias adjusted to correct spec.

ü Switches and controls now clean sounding and performing solidly.

 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.

This is one the second Marantz 1060 we've had in 23 years, and we've owned this one for over a decade before deciding to finally get it into the shop for it's restoration / service. 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.
     
On our test bench the internal amplifiers of this particular unit, #...1938, produced 19 Volts per channel at 8 Ohms for 45 Watts per channel and 13 Volts at 4 Ohms for 44 Watts per channel via discrete, TO-3 / Metal Cased outputs.
Idle current draw 0.4A.
DC out measured at <3mV on either side.
Very quiet with Floor noise measured at <00.0mVAC.
    ____________________________
 
Probably "The Definitive" of Marantz Integrated amps, and the one that most are compared to. Heck, just check how long it's model was kept current. 6 YEARS! It wasn't until 1979 that they changed it to the 1070, which has the 'less desirable', 'linear' tone controls.
Just the right features & sonically magnificent! Great amp for home or project recording studio use.

Marantz 1060 Integrated Amplifier Features and 'Creature Comforts' include:

- Produces full power into only '8 Ohms' (most amps can only produce their full power potential into 4 Ohms)
- Speaker selector for Main or Remote, A+B or Off 
- Hi filter for reducing tape hiss / electronic hiss & noise- and record static
- Low Filter with 15Hz cut-off built-in for cutting turntable rumble
- Super quality volume control
- 3-Band EQ / Separate Bass, Mid and Treble with high quality de-tented controls
- Pre-Out / Power-Amp Loop (includes pair of original Marantz Jumpers)
- Loudness function (boosts EQ on Bass and Treble, while cutting mids for a fuller sound at lower volume levels)
- 'Stereo / Mono'  selectors (Mono 1 & 2 IN switch)
- Tape Monitor Loop with both RCA and DIN I/O's (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 w/ 'Built-in' phono pre-amp
- Tuner input (may also be used for Video / CD / DVD / LD / VCR / DAT / MP3 / iPod® / iPad® / iPhone® / iPod® / iTouch® / iGadget / eReader / MP3 / XM® / SIRUS® etc.)
- Dual AUX inputs w/ "AUX 2" via front mounted, 1/4" jacks. These can also double a 'Microphone Input' jacks (be careful with 'home stereo speakers' when using microphones on stereo gear!!!)

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

CLASSIC & VERY EARLY FUKUIN ELECTRIC CO. / PIONEER HI-FI / STEREO SPEAKERS
PIONEER "TITAN IV"? SPEAKER
Circa 1960-61
for sale
Massive and VERY EARLY Pioneer 'Hi-Fi' speakers, direct from Japanese market. These appear to be original, factory built, Pioneer Titan IV speakers. The 1960 driver complement in these were typically offered in the US as 'kit' form (due to impracticality of SHIPPED such voluminous cabinets from Japan) but according to their consignor, these were brought over by a GI on military transport, so economics was not an issue. He purchased them originally in Japan. These are among the first drivers branded 'Pioneer' from the original parent company Fukuin Electric Co. The company changed it's name to Pioneer in 1960 or 61. There are probably less than an 'handful' of these in the US (if that) and probably only a few dozen in the world. If you want the rarest of the rare Pioneer speakers, here you go. These things are MONSTROUS!
"Hey, Go Big or Go Home!"
Their huge drivers are both efficient and seem to be power capable (handled our Hafler P225 well, but as always, be careful with irreplaceable 'vintage speakers).
Our speaker tech has completely gone through and 'Certified' these.
He has completely disassembled them further, testing all drivers independently. No material issues found with any of the drivers. Each was 'swept' with the AF generator while removed. All drivers were re-installed with the addition of gasketing material to further seal and eliminate any ‘flange to baffle’ rattles and buzzes. Attenuators removed and cleaned for ‘static free’ operation. Gasketing added to the attenuator plates prior to re-installation as well. We also 'modernized' the input connectors (gasketing also added to their mounting plates). Gasketing also installed on rear panel, prior to re-installation. He also installed new, height adjustable, leveling, 'glide' feet. Entire speaker system then swept with our AF generator from 20-5,000 Hz and feeding them with the output from our Hafler P-225 Pro Power Amp, looking for any irregular vibrations / anomalies in either the drivers. driver mounting, crossovers or cabinet structure integrity.  Next we auditioned them with our standard, 'abusive' demo / testing CD's / cuts running the gamut from Dire Straits, 'Brothers in Arms', TLC 'Fan Mail', Allison Kraus and Union Station, Nickelback, a digital recording of a cathedral pipe organ, our 'Usher Speaker' demo CD (no not that Usher), 'Friday Night in San Francisco', with Al Dimeola, John McLaughlin and Paco DeLucia, Nickel Creek's, "When in Rome" from the CD, "Why Should the Fire Die", Jennifer Warnes, "Famous Blue Raincoat", and a few others, all digitally recorded and some 'DDD'.
Very 'large' sounding cabs. I did prefer them with an EQ, but I know you 'purists' would 'cringe' at that idea.
 Pioneer Titan IV Speaker Features include:
 
- 3-way, Bass-Reflex design
- 12" Pioneer PW-30C, Cast Aluminum frame, Low Frequency' Driver (woofer) w/ vented Voice Coil and AlNiCo magnet / motor.
- 6" Pioneer PM-16B midrange 16 Ohms & AlNiCo magnet / motor.
- 3" x 2.5" Pioneer PT-6, 16 Ohms Horn Tweeter w/ AlNiCo magnet / motor.
- Infinitely variable L-Pad for Tweeter attenuation
- Pioneer DN-7 2-Way / 3-Way Crossover
- 11.5" x 8" Tuned Port

Pioneer Titan IV Speaker Specifications:

System Design: 3-Way, Bass Reflex
Driver Compliment: PW-30C 12", Cast Frame Woofer, PM-16B midrange / Squawker, PT-6 Horn Tweeter & DN-7 Crossover.
Frequency Response: ~35-20,000Hz
 Nominal Impedance: 16Ω
 Cross-over frequency: Pioneer DN-7 500Hz & 4kHz @ 12dB / Oct
Power rating: likely 25-40 Watts
 
The real wood, Mahogany veneer cabinets in INCREDIBLE shape, as are the original grills. They are virtually blemish / mark free and look like they could still be on the original show room floor. The cabinets have just had a fresh coat Howards 'Restore-a-Finish' and 'Feed-n-Wax' rubbed in to bring out their original luster. Again, our speaker tech has completely refurbished, tested and Certified these speakers performing the previously mentioned processes.
 Great speaker for a lower powered 'vintage' Hi-Fi system, or that low wattage or 'single ended' tube amplifier. They look, work and sound great! Cabinets measure 38" H x 27.25" W x 17.75" D and weighs a hefty 90 lbs each (due to their huge size once packed, the P,S & I on these to much of the lower 48 states of the US would run approx $450-$650. Locations such as North Eastern States, North Western Washington or Southern Fla would run more). Includes our standard 90 day limited warranty (excluding problems due to under / over powering.

 There aren't many ESB's in North America, as they were imported in limited quantities from Italy, where they comprised approx 25% of the speaker market!
 ESB (ELECTROACOUSTIC SYSTEMS BUILDING)  They are an impressive speaker in design, build quality, construction and sonics. Their detailed and balanced sonics are accomplished via a couple of design characteristics. One is the 'coupled' Midrange and Tweeter design. The other would be the a radical modification of Horizontal and Vertical alignment. From a 1984 review,
"A key element in the design of all the Series 7 speakers is what ESB calls DSR (for "distributed spectrum radiation"). which is intended to maintain accurate, consistent stereo imaging over a wide listening area. Vertically, this is achieved first by building the mid- and hi-frequency drivers on a single mounting flange, minimizing the distance (and therefore the interference) between them, so that they act as nearly as possible like a single point source... The method ESB uses to stabilize the image horizontally is a refinement of a familiar technique. 'Toeing in' a pair of speakers so that their forward radiating axis cross slightly in front of the listening position usually broadens the area in which you can sit without the stereo image collapsing into the speaker nearer to you."

These are great performing speakers for most any genre of music. We extensively tested them with our barrage of material. They were very balanced and handled power well. Probably not a speaker for every week party's, but for a great 'large' sound, you'll love them. These are in beautiful physical condition as well.
Features include:
  
- 3-Way, Acoustic Suspension / Infinite Baffle cabinet design
- Asymmetrical / Mirror image cabinets w/ angled high-frequency baffle
- 10" Woofer with fresh foam surrounds (were re-foamed prior to their arrival to our shop. The tech utilized 'Cerwin-Vega' surrounds, which are 'red' in color, then 'blackened' them, with questionable success. Sound and perform fine, but noticeable cosmetically)
- 2" Hemispherical 'coated' silk dome midrange w/ heavy duty motor 'coupled' to tweeter plate
- 1" Hemispherical 'coated' silk dome tweeter w/ heavy duty motor 'coupled' to mid plate
- Heavy duty, Banana / Binding Post speaker input terminals
- Externally located, independent, glass fuse protection for all 3 drivers
- Incredibly well built crossover.
- Heavy build, 'acoustically solid' cabinets
  
Specifications:
  
System Design:  3-Way, Infinite Baffle / Acoustic Suspension
Frequency Response:  45Hz - 20kHz ±3dB
Crossover points: 600Hz & 6,000Hz
Sensitivity: 87dB @ 1W, 1m
System impedance: 6 ohm nom / 5 Ohms min.
Recommended Amplifier rating: 40 Watts minimum, and were originally tested when current with 300Hz bursts at 500 Watts

Our speaker tech has completely gone through and 'Certified' these. The surrounds were recently replaced with 'Cerwin Vega' 'Red' foam, that was 'stained' black, prior to arriving to us. We have completely tested them with both recorded material, PN 20-20k and swept them with our AF generator from 20-5,000Hz and feeding them with the output from our Hafler P-225 Pro Power Amp. Then further auditioned with a myriad of our difficult to reproduce 'test' CD's.
 The real wood veneer, cabinets in beautiful shape with no serious 'battle scars'. Have been given a coat of Howards 'Restore a Finish' then buffed w/ 'Feed-n-Wax'. With the exception of one missing logo, the original black knit grills are in great shape and the original frames are structurally sound.
Again, these are great looking and sounding speakers and would be happy coupled with most any medium to large receiver / amp. Cabinets measures 37.5" high x 15" wide x 11" deep and weighs a hefty 55 lbs each. Includes our standard 90 day limited warranty (excluding problems due to under / over powering).

(Due to the dimensions and / or weight of these speakers, Packing / SHIPPED will be somewhat more 'involved' than typical. Custom, double-wall boxes will be manufactured specifically for them. While we order custom built boxes often, this can sometimes delay SHIPPED by 5-10 days)

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).
