Tannoy PBM 6.5
The Tannoy PBM 6.5 much used by studio's worldwide


"The transportable and extremely powerful PBM 6.5 is the result of many years of fine tuning of the PBM concept. Featuring a unique layered injection-molded bass driver and a superb high frequency unit, the 6.5 is the ideal monitor for almost any project production environment. The drivers are controlled by a completely redesigned hardwired hand selected crossover providing uncompromising detail, precise spectral resolution and flat response...The fully radiused and ported cabinet design reduces resonance and diffraction while providing deep line and extended bass. When quality. accuracy and the legendary Tannoy sound are available at such a remarkably reasonable cost, there is simply no other choice."

I have a pair of PBM 6.5mkII. They served me very well for many years. Musical and practical speakers.”

“I use Tannoy - PBM 6.5 for mastering and it works great!!”

“I can't say enough good things about these dynamos. I have used them in my row home at ungodly listening levels as well as at a nice respectable volume. They are clean, clear, transparent and really natural sounding. It's what a studio monitor is supposed to do, add nothing other than what is contained in the program material. Where they really shine is with vocal, midrange and horns. Crisp, sparkly, shimmering highs explode from these in a way that belies the diminutive size. Best when elevated and placed carefully away from a rear wall as the rear firing bass port's placement is the key to the bass definition. Never tiring to listen to and a great value.”

“I own a pair of PBM 6.5 for recording and mixing purposes for the last 19 years!!! The response and image projection is outstanding considering price range. For they are a classic for music and post production….They are as important as Yamaha's NS-10m. Without wearing my ears out.”

“I loved my PBM 6.5s - used in studio and for listening.”

“Thanks for the web site! I bought mine "used" from a music center that has since closed down. The where used for the first city fireworks extravaganza here in Houston TX as monitors for some famous composer that put all of music together. I was told he was pushing 1000 Watts through them. When I heard them, they were playing through a 400 watt system with clarity I never heard before in regards to monitors. No coloring of the sound make mixing perfect. EQ later. Play them through a straight amp and put at least a foot of space behind them with no foam or baffling.”

“I loved my PBM 6.5s - used in studio and for listening.“

“I have had my pbm's for at least 15 years and they are still the only ones I have in my home project studio. Still going strong.”

“I have had my PBM 6.5 for 25 years and they are still going strong. I use them in my home studio Dj'ing and mixing music.”

Original observations / conditions: "Very dirty outside. Stiff PR arm. Playback un-even from L to R. Both trident spindles bent. Transport cam dogs in good shape. Typically dirty & intermittent pots / controls. 60Hz hum on 1 channel. Auto-Reverse mechanism for head movement sluggish (too sluggish to be usable and causing the afore mentioned "hum"). Right channel meter 'wigs' out upon initial power-up. Missing both transport control handles. Missing pinch roller. Voltage incorrectly set to 110VAC (should be 117 or 120 VAC).

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

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. We also set the voltage selector to correct, 120VAC.

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

ü Internal Transport 'cam dogs' on this deck are the 'later' versions and resistant to deterioration (MUCH UNLIKE most other Akai decks) (in fact, these are in perfect / NEW condition inside)

ü Entire transport was disassembled down to the chassis, and every mechanical part was removed / disassembled, cleaned, re-lubed with synthetic lube and reassembled.



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

ü Capstan & flywheel removed, bushings and axel cleaned and re-lubed

ü Flywheel thrust bracket removed, bearing surface cleaned and re-lubed, then reinstalled and adjusted.

ü Both spindle hubs disassembled, and trident pins straightened

ü Drive motor inspected, cleaned and re-lubed

ü Knurled drive pulley cleaned of old rubber residue

ü OEM Pinch roller sourced, then resurfaced / reconditioned, and lubed prior to re-install

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

ü Brake pads cleaned / reconditioned

ü Brakes adjusted on fast wind modes also.

ü Back tension adjusted on both reel tables.

ü Brand new, MCM #42-860 'Main' drive / capstan belt installed

ü Brand new, #041 'Tape Counter' belt installed

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

ü All transport functions now test perfectly, following above adjustments, Reel Start and Stop tested at beginning, middle and end of 7" tapes

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

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

ü We also adjusted the reel table heights.

ü Meter lamps replaced with new #25-500

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

ü Mic / Line control pots cleaned for static free performance

ü Deck has been fully calibrated to factory manual specs adjusting PB levels, Meter adjustments, Bias / Frequency adjustments (VC1& VC2), and internal record levels, tested, with Nortronics, Panasonic, Sony, Soundcraft, STL, TEAC and BRL alignment / test tapes (see resulting record level listed below). Biased best for Ampex GM456 / ATR Reference tape and records on Maxell UD also very well. Best performance when recording at -3dB (most manufactures test at -20dB).

ü Speed tested to .996% accuracy (1kHz = 1.004kHz)

ü Floor noise measured at >-54dB following above procedures

ü Following the above work and calibration, Recording tests performed with Ampex GM456 (again, same formulation as new ATR tape) and Maxell UD (Gold / Black) Tapes.
Here’s the results;
Maxell UDXL @ 7.5ips. 1kHz @ 0dB = L=-4dB L & R = -1.0dB (best to record @ -3dB on 'Source')
Maxell UDXL @ 7.5ips. White Noise @ 0dB = = L=-3dB L & R = -0.5dB  (engaging "EQ" adds +5dB L&R)
GM 456 @ 7.5ips. 1kHz @ 0dB = L=-2dB L & R = +1.5dB (best to record @ -3dB on 'Source')
GM 456 @ 7.5ips. White Noise @ 0dB = = L=-2dB L & R = -0.5dB  (engaging "EQ" adds +5dB L&R)

We then tested Ampex GM456 with Recorded program from "ddd" source extensively and deck performed well. I know that a 'copy' CANNOT sound better than the source, but I swear that repeated recordings seemed to be "fuller" sounding than the 'source' material.

ü This Akai GX-210D functions, plays, and records perfectly (and we really put them through the paces, testing both with well mixed, recently recorded CD material and CD recorded / factory test tones looking for correct head Azimuth and speed accuracy).  (Total time investment in refurb / testing ~ 15+ hours).

This one made it through and all functions test great! Looks and sounds great too! Deck looks good with a few minor cosmetic issue; A bit of discoloration to the face metal if the light is angled just right, a minor dent in the face panel about 'mid-deck', a bit of dry cracking on one of the rubber reel trims, and the back edges of the side panel, wood grain, vinyl is peeling a bit (see photos above). Nothing too distracting. And again, following the extensive refurbishment listed above, the deck works and sounds great!

ü  Our technician has EXTENSIVELY gone through and 'Certified' this unit, cleaning inside and out, lubricating mechanism, adjusting tone arm lead out and testing performance.
 
ü Entire automatic mechanism COMPLETELY disassembled, de-greased, cleaned and re-lubed, (never an easy task on 'auto' turntables) including; the 'Actuating Slide and Pawl', and both plates.

ü 'Speed Change' mechanism disassembled, de-greased, cleaned and re-lubed

ü All internal rubber parts reconditioned including, of course, the idler wheel.

ü Drive motor completely disassembled, cleaned and re-lubed.

ü Steuerpimpel replaced (this is a 'MUST DO')

ü Steuerpimpel glider pad in fine shape, and fully operational
 
ü Platter bearing disassembled, cleaned of old lube and re-lubed.
 
ü Gimbal bearing, counter weight and anti-skating all adjusted and verified for accuracy.
 
ü Tone arm Lead-In and Lead-Out.
 
ü Tone arm bearing perfectly smooth in operation.

ü Idler position centered for more positive speed positioning w/ selector.

ü Original Dual Changer / Stacker Spindle inspected, re-lubed with 'dry lube' and EXTENSIVELY tested on multiple tables (see below)

ü Burnished RCA output connectors under chassis

ü He also replaced the anemic, factory RCA cables, with some much higher grade, fully shielded interlink cables, w/ 24kt gold RCA connectors.

ü Original platter mat warp & bubble free.

ü Re-glue, and Lemon Oil Teak wood veneer case / base

ü Proprietary Dual 'cartridge sled' inspected, and had both mating contact sets burnished (primarily to address 60Hz hum)

ü New Shure M91-E, Elliptically cut, Diamond Stylus, installed on the Shure 'magnetic' cartridge. Tracking and Bias force also re-set to 2g.

ü Tested / analyzed and passed for motor noise and 60Hz hum.

ü Speed checked and verified for accuracy with technician's factory test strobe disc.
 
ü He also did an 'orbital buff' to the dustcover and it looks GREAT! Has cracks at each rear corner that have been 'plastic welded' solidly back.

ü Table cosmetics detailed.

ü Unit tested with our myriad of test records, one of which included; Shures' 'Cartridge Obstacle Course' record

Restoration entailed approx 17+ hrs w/ followed with about MANY hours of testing w/ many albums (mostly because we enjoyed having a 'quality' changer on one of the test stations to listen to).

As this turntable has a 'magnetic cartridge' (unlike most 'stacker / changers' which have 'crystal / ceramic / piezo' pickups) you can readily connect this table to any receiver or Integrated amplifier input. For a basic system, or wanting to get introduced or re-introduced to stacking vinyl records, this is a great table.

You can readily connect this table to any receiver (including 'modern / A/V / Home Theater receivers) or Integrated amplifier with a standard magnetic phono input, or an external Phono Pre-amp. To connect to computer for burning CD's just order one of our inexpensive Phono Pre-Amps and cable kits.

 Plays 16, 33, 45 & 78 RPM records. Selects 7", 10" or 12" record size. As stated above, this table has had EXTENSIVE refurb / restore work. Cosmetically, the table looks great.
 Again, our turntable tech has completely and EXTENSIVELY gone through this table (total tech time ~17+ hours).  
Following, and ONLY DUE TO the above restoration / refurbishment, the table starts as it should, and end's as it should with no 'end groove hang up'!  (While Dual purports stacks of 5 LPs as 'typical', normally you should typically only get about 3-4 on a stack with no issues, and you won't always get '6' to work, but... this table, #2184 was test played thru 25+ cycles and tested thru multiple stacks, with 6X LP's stacked with no issues!!! Occasionally you'll have a record 'hang up' or 'double drop', but that's almost always due to errantly drilled, elliptical or center holes that are 'too tight' in one of the records.
 Overall the table works beautifully and all functions now work GREAT! We also re-installed a Shure cartridge with a brand new M91-E stylus and optimized the table for it.  (If you prefer an up-grade you may also choose from our selection of new Audio Technica cartridges that we can also set up and ship with it for the additional cartridge cost.) You can readily connect this table to any receiver, Integrated amplifier with a standard magnetic phono input, or a Pre-amp. To connect to computer for burning CD's just order one of our inexpensive Phono Pre-Amps and cable kits. Again, this table looks near new and works great!!
 
Famous, sought after, and one of their more 'durably designed' DUAL 1209, fully automatic changer phonograph. This is one of only two "Dual 1209s" that we've had in over 20 years that we've restored (due to finally having a technician that's up to the task). Very nice Dual 1209 Stacker / Changer / Single play, Fully-Automatic turntable. One of the most sought after Dual's due to it's 'simple and durable' design. Very difficult to 'break' one of thes.
These are very well built turntables featuring an adjustable speed belt drive platter, but here's the VERY IMPORTANT POINT about the 1209.  It is one of the few Dual models, offering 'adjustable platter speed' that does NOT utilize a 'toothed belt'. It uses a 'tapered' motor drive pulley. The original 'Toothed' belts, utilized by Dual on MANY of their turntables are now 'UNOBTAINIUM' now, and any of the original / NOS ones still floating around are likely 'dry rotted' and useless. We've tried 'O-rings' (both single and double) with limited success. NOT to worry on this model as it doesn't use that system at all (and that is VERY important).

Dual 1209 Features:
 
- Fully automatic operation
- Super heavy platter
- Idler tire drive (no belt needed)
- 'Pitch Control' does not utilized the 'toothed belt' that is now ''Unobtainium'!!!
- Single play or Stacker / Changer operation (both 'single and LP 'stacker' spindles included with this one)
- Tone arm cueing lever ('Cueing function defeated when used with 'stacker spindle' for safety)
- Record size selector for 7", 10" or 12" discs to adjust starting position and as a safety to insure that the stylus is not lowered onto the platter with out a record
- Adjustable Platter Speed control (does require 'monitoring' chart)
- 33 1/3, 45 & 78 RPM speeds
- Low mass, straight, metal tube tone arm
- Standard 1/2" mount cartridge head shell
- Tracking force and Anti-Skating adjustable ('course' tracking by 'weight' and 'fine' tracking by 'spring')

Dual 1209 Specifications:
 
Motor: Synchronous, Split/4-pole Motor, with 'Radial-Elastic' suspension
Drive: Idler Tire / Rim Drive
Platter: Non-Magnetic, Dynamically Balanced. Weight 1.8Kg / 4lbs!, 270mm
Pitch Control:  6% (again DOES NOT utilize a 'toothed belt')
Wow & Flutter: ± 0.09%
Speed Accuracy deviation: <0.09%

Tonearm: Extra-long, torsionally rigid metal arm, mounted on 4 point Gimbal type on vertical needle bearings and horizontal ball bearings with hard, and polished races. Dual 'Sled Head' headshell.
Cartridge: Accepts all 1/2" mount with a weight of 1-12 grams (incl. mounting)

Again, as previously stated, the table has just been completely gone through by our senior turntable technician and is "Ready to Go"! Following refurbishment / and final inspection / sign off, the table has gone thru a minimum of 25 play cycles, including a minimum of 6 plays of 6x record stacks. You will not be disappointed in this table for all around use. Comes with and original, Dual "Stacker / Changer" tall spindle we ordered from Europe and 'short / single play' spindle and a pair of 'up-graded' RCA interlinks. Measures 18" wide x 16" deep x 9" tall and weighs a heavy 16 lbs unpacked. Includes our standard 90 day limited warranty.

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!)

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

-           Cleaning Swab

This clarinet retails for $925.00 (US).

STEREO SPEAKERS
SYSTEM 300
Circa 1981-'85
Made in USA
CURRENTLY HELD FROM SALE
for sale
A bit short in the looks department, but long on sound.
We have completely tested them with both recorded material, W/N 20-20k and swept them with our AF generator. These Jensen "System 300" speakers are very accurate and impressive sounding.  Features:

- 9" woofer
- 1" cloth soft dome tweeter
- Acoustic Suspension cabinet design
- 8 Ω

Foam surround on 9" woofer in fine shape with years life left in it before it will need to be replaced. Medium-dark Oak wood grain vinyl wrap finish in decent shape with a few normal scuffs and dings. Nothing too  distracting from overall appearance (see photos). Original brown grills in fair shape as well with normal amount of snags for 15 years old and unfortunately the small plastic Jensen badges are missing. Grills also have minor, light colored staining on lower 1/3 of each. Speakers test and sound great. Each measures 23" high x 13" wide x 10" deep and weighs a 23 lbs unpacked. Includes our standard speaker warranty ( excluding problems due to under / over powering).
