“Crumar Bit 99 Analogue synthesizer – Needs repair.
It works but has some problems.
Mainly needs to get up to temperature before resonance kicks in on filters – suspect a cracked pub track or wire
Also some note rotation oddity, some notes don’t play. but this is not a keyboard/ keybed problem. Its completely random.
All 6 CEM 3328s are good and work. So could be used as donor.
Probably needs a re cap and check all pcb traces to make working fully again,
These are awesome sounding synths, give oberheims and JP6s a run for money.
Sonically kick Junos out of the park.
Once I got this many years ago I sold my Juno as better richer sounding and much more versatile.
Has Midi, and there are midi SYSex editors for it. However the keypad entry is pretty quick once you get used to it. ” Click here to search for synths on eBay
“This has been hooked up and played. That’s all I know. My son’s band used it for a few summers a few years ago and it worked fine but I’m not a musician so I couldn’t tell you if the B key is flat or whatever is off. There are no broken knobs, keys, etc. No dents. See photos.” 
“Oberheim Matrix 6 Analog Keyboard Synthesizer. Condition is Used., overall good working condition.” 
“Up for sale is the legendary oldie but goodie,oldie but basically like new goody if you can believe it. The Oberheim Matrix 6. Yes im talking about a basically untouched classic piece of vintage gear in basically new condition !!, This piece has never been serviced, repaired or never even been played for more than even a few hours in TOTAL. So in other words its basically like walking into a Sam Ash or other music store between 1984-1987 an asking “may I please have a Oberheim Matrix 6″. I was thinking about keeping it as a show piece because of its age and history, and not to mention it is sort of a family heirloom, but I need to buy other gear, I have shown numerous pics in this posting but if you require additional pictures please don’t hesitate to ask, and that goes for any additional questions too. Included is the original foot pedal and power supply, sorry but I don’t have the manual, I don’t know what happened to it, but it can be downloaded online free of charge.”

“Hello, this listing is for a Monome Norns and a 128 Grid, bought new by me in Nov 2018 from the states. With import charges this came to a few quid short of £1,400. Both items are working great and operate as you’d expect. Please bear in mind that much of the Norns software is still in active development. Check out the Monome Lines forum. At the time of writing I have the latest version of the Norns software installed.
“Absolutely fantastic condition.
“Only 2 owners. Purchased from a Pawn Shop in 1982 Los Angeles. Excellent condition. Works as it should. Serviced recently. One coffee ring on the side wood panel. Sounds extremely fat. Great monosynth with duophonic capabilites. Filters are very impressive.” 
“Moog The Source Analog Synth Synthesizer Big, Fat, Moag Sound, I hesitate to sell it. Normal signs of wear on the edges. Overall, Very good condition. This Source operates so nice, fresh and reactive, springy and alive.
“This synth has had a full service – every slider has been cleaned or replaced if needed, one of the MM5823N divider chips was replaced, a 2n3906 transistor was replaced in the first oscillator. Also, the synth received a full recap using high quality Nichicon electrolytic capacitors. I performed a couple standard mods and changed the RCA out to a normal 1/4” jack along with increasing the overall output volume. The nasty ass foam protecting the sliders has been cleaned off and replaced, along with new knobs and slider caps. All keys were removed and polished. This synth looks lovely and will sound beautiful for years to come. Cosmetically speaking, it looks pretty good overall and has a few cracks in the overlay, also a few flecks of what seems to be white paint. Other than that, it’s quite pretty for a synth this age.”
