“Very rare sale of a Yamaha CS-80!
Complete with Kenton Midi kit

All voices and functions are in perfect working order. This was given a thorough electronic overhaul by CS-80 guru KSR three years ago with over £1500 of new IC devices fitted. KSR also fitted a new Kenton Midi kit at the same time. It’s been sitting in my home music room ever since.

Cosmetic condition reflects its 42 years, as you will see in the close-ups. But the key thing is that she sounds stunning and importantly, the felt pitch bend strip is in perfect working condition, as with the holy-grail unique ability of the CS-80, Polyphonic Aftertouch.

Offers welcome, but bear in mind that when you CAN find one for sale, they are into five figures!”

cs80 “Yamaha CS-80 CS80 Vintage Analog Synthesizer Rare & Superb

This one is in superb condition. It works but it needs to be tuned properly. It comes with a custom made road case with wheels. It also comes with a kenton midi retrofit kit. I’m thinking of doing the upgrade is it doesn’t sell.

It is a rare opportunity to grab this one. I am sizing down on synths, got too many. ” Click here to visit listing on eBay

cs80 “Released in 1976, this vintage Yamaha CS-80 is considered one of the most famous polyphonic analog synthesizers ever built.

The synth for sale has been used on records for several high profile artists including Primal Scream and Noel Gallagher.

It is in full working order except for one oscillator which is in need of tuning. It is in very good condition with only the usual marks and scratches you would expect with a vintage synth of it’s age and comes with it’s original top cover (not pictured).” Click here to visit listing on eBay

It’s in full working order and the keyboard itself is in good condition has the odd mark and the case has a few scratches on it. We will consider sensible offers but this is a piece of musical history.” Click here to visit listing on eBay

cs-80 “I bought this fine instrument in 1980. It had one owner before, and the previous owner did not transport it. I briefly toured with it in a private tour that I cared for it myself, but the rest of the time it has been in my home studio, or in a pro Calzone road case. The road case has new foam inside, recently installed by Georgia Case Company. It has a remarkable quality preservation, especially the keyboard, and bank of controls, and the interior. There is a new/rebuilt power source, and also a new ribbon controller.

As far as I can tell, all of the functions, that control the sounds, i.e., portamento, glissando, filters, octave controls, etc., function correctly.

The instrument does need some work, and the facilities in Atlanta, were unequipped to fix the problems, due to the lack of knowledge and experience about the instrument. There are quite a few places in the USA that not only stock parts for this instrument, but are capable of totally fixing the unit to its original shape and function.

What doesn’t work:

The keyboard doesn’t correctly track the notes played, and will need competent calibration and tuning, and possibly extra parts replaced.

The ribbon controller is new, but it doesn’t function

The lowest key doesn’t sound at all

The sound settings all work except the Funky 3 setting which does not

There is no white noise functioning that I can tell

The after touch doesn’t work

All of the top bank, and preset functions work, except what I mentioned above

The cover, and sides of the unit are quite good cosmetically, although they have a few dings.
The bottom of the instrument has some dings on the vinyl, but is not real bad, for its age—only one place about a 3 inch square area is scuffed down to the wood. Most all of the scuffs are on the vinyl covering the instrument, and are small. There is one place on the back of the instrument brown wood area, that is scuffed.

The stand has been painted black but it works well. One of the attached screw handles is gone, but replaced by a bolt and washers.

All of these non-functioning items are fixable by a competent lab. I have adjusted the price to reflect the extra work needed.

Absolutely no returns, you are accepting it as an as is item, fully knowing that it needs work.” Click here to visit listing on eBay

cs80“A Yamaha CS80 Analog Synthesizer in working condition. I had it diagnosed in July by the renowned Analogue Lab in Long Island City, New York. There’s 1 dead voice (of 8) on bank one and 3 dead voices (of 8) on bank 2. The pitch bend ribbon needs to be repaired and all controls need to be cleaned. It could also use a full calibration/tuning to factory spec. Please see the photos. ” Click here to visit listing on eBay

cs80 “I’m sadly having to part with my beautiful Yamaha CS80 keyboard which has served me well in my home studio for the last 30 years or so. It is in good working condition though will be sold as seen, as I’m afraid I can’t be responsible for anything that happens to it once it’s left its long-time home. It’s never needed servicing in all that time, but is probably rather dusty. It comes with its sturdy metal ‘legs’ and also has its ‘top’ which is somewhat scratched, dusty and rusty round the hinges with a few small tears to the surface. The winning bidder must be able to get it safely down one flight of stairs (with bend)… it’s VERY heavy!” Click here to visit listing on eBay
