“I bought this years ago to restore and just repaired the power supply temporarily, as you can see by the wire nuts. It turns on and makes some cool sounds but clearly isn’t working well. To be safe I am selling it as not working, for parts, but many lights come on and buttons react, and keys make sounds.” Click here to visit listing on eBay

“As you can see it’s got some graffiti from the 80’s. I bought it in 82. The keyboard is a bit uneven in key height but all the keys work. All the knobs and everything works but it could probably use a cleaning.” Click here to visit listing on eBay

“1984 Sequential Circuits DrumTraks Drum Machine in Working Order! with some quirks…

*Quirks….the potentiometers on individual sound/drum and Tuning are finicky…usable but finicky
meaning they will hit their stepped settings (maybe mark with a pencil) but you need to spin slowly

volume is a little crispy

A Decent Usable Example” Click here to visit listing on eBay

“You are looking at a Sequential Circuits Prophet 5 Revision 3.3 serial 4266 with factory midi kit installed. The revision 3.3 was the last version of the Prophet 5 produced. It has the latest 10.5 system ROM and has 120 patch memories. This Prophet has been fully serviced by Norm Leete in Gloucestershire and has had a new memory battery installed. Norm is well respected and does much of the servicing work for the VEMIA equipment auctions. The keyboard plays like new as it has been fully reconditioned with new rubber key bushings. There are a few minor marks here and there but overall I would say that this Prophet 5 is in excellent condition and in perfect working order. The original user manual will be included. I have owned this synth since the late 80’s and will be very sad to see it go.” Click here to visit listing on eBay

“For Sale. My beloved Pro One synth which I have owned from new. It has NEVER BEEN GIGGED and has spent it’s entire life flightcased or sitting in my studio. There are two small cosmetic scratches (shown in the pics) which don’t affect its performance in any way. Like all things of its age, it could do with a spray of pot cleaner (and I would recommend that the buyer does this), but is in full working order and sounds great. Extremely rare now and hard to find in this condition. If you love that fat analogue sound, get bidding and you wont be disappointed. ” Click here to visit listing on eBay

“Cosmetically there are minor scuffs and fingerprints around knobs however nothing that would decrease its value. Woodside panels are well taken care of. Everything as far as the sound is concerned is working 100%. All pots and buttons function beautifully as well as inputs and outputs. Gli Gli upgrade sounds great helped with response timing and filled out an already rich sound.” Click here to visit listing on eBay

“Good shape, everything works, some physical wear is evident. There is some rust around the holes for the rack screws and a few minor scrapes in the finish. There is also some residue on the bottom, where there may have been rubber feet? The pictures give a good indication.

I just today tested loading and playing sounds, as well as all the buttons and knobs. All controls and lights are functional. The disk drive has been replaced years ago, and it does work. The new drive is smaller than the original, so there is a gap between the drive and the control surface of the sampler. This is shown in the pictures. ” Click here to visit listing on eBay

“Everything works except that it will not save patterns when it is turned off. I believe The battery needs replacement. also the two front screws that hold down the face of the machine are missing” Click here to visit listing on eBay

“This is a very rare Sequential Circuits Piano Forte made by Seil. It has a different fuse cap not shown in the pictures and I will include the missing TMS3617 Top Octave Chip missing on the upper voice card as shown in the pictures. I purchased the chip to try to repair this unit but no longer have the time. I purchased the unit without the chip not knowing before hand so I believe the unit will still have issues even if the IC is installed. It only makes a slight clicking sound when keys are pressed. No other testing was done. It looks to be in pretty decent shape and clean as you can see by the pictures. It is being sold “As Is”. Great refurbishing project!” Click here to visit listing on eBay

“Selling my p600 of which I am the original owner.
I had it refurbished and the Gligli modification installed in 2015 by Wine Country.
You already know that this is the original MIDI synth with a distinctively aggressive sound.
Includes original manual.
Includes original ePROM incase you want to de-Gigli-ize it.
The unit is in excellent condition for it’s age.
It has a couple of small dings on the wood ends which you can see in the photos.
There is a piece of electrical tape covering the Sequential Circuits logo on the back. (Back in the olden days of the original synth wave we did not want advertisements on stage ;-)) ” Click here to visit listing on eBay

“Missing buttons for track 5 and 6 and also sound select 1 and 3, transpose and time button also missing. They are just simple rubber buttons and should be able to be replaced if you can find some. The knob for the master volume is also missing.

Some extremely light rust on the left hand side. Does not affect playback.” Click here to visit listing on eBay

“Collection only.
Prophet 2000 sampler. Beautiful condition, all working and has had the disc drive replaced with a SD card reader and has loads and loads of sounds on the SD card.
Lovely bit of kit that I no longer use. I bought this for a sampling project about a year ago where I needed the 12 bit sound and I payed over £550 for it on ebay (it is a beautiful example of this sampler). I have used this sampler only a handful of times and I no longer need it.”

” Up for sale is this rare, vintage 1980s Sequential Circuits Multi-Trak 6-voice polyphonic analog synthesizer. Synth is in overall good condition. Shows minor signs of wear & use. Has a massive sound & really fun to mess with, especially the chorus section! All the parameters seem to function properly, however the Pitch Bend wheel is not working (feels stuck). The ModWheel is working properly though and feels great. Comes with power supply cord.” Click here to visit listing on eBay

“Offering up this analog gem. It’s been in the family for decades, but hasn’t seen much use lately.

I have extensive electronics experience, so I serviced it. I cleaned the controls, performed the battery life modification, and installed a new Energizer Lithium battery. Should last 10 years before it needs service again. Other than that it is unmodified and it is a revision “A” board. The patch memory was lost when the battery died, but I programmed a handful of sounds to test out the features. There is a lot of information regarding the original 100 presets online if you are looking to restore the factory samples.

Everything except the “tape drive” functions were tested. All controls, MIDI and audio I/O are 100%.

The power cord insulation is cracked as noted in the pictures. There are scratches on the bottom and a ding or two on the control plate. Otherwise it is excellent!”
