Yamaha CS-80s synths on the market and sold

Below are Yamaha CS-80 synths and parts that are either on the market or have sold. My purpose with this post is to follow the market and keep a registry of sorts. I’ll try and keep this post up to date as CS-80s are listed and then sell. Maybe someday I’ll get one!

Update July 3, 2021: Right now on Reverb you can buy an original CS-80 workshop / service manual for $569.67. The odd asking price is probably because the listing is out of London UK and in British Pounds. Like the legs that sold a few days ago, I wonder if this is a lot of money for a manual, or a good deal for an item that helps complete a CS-80 package. I admit, I am the sort who buys original manuals for all my Synthesizers and doesn’t give them up when if I sell the synth.

Something to think about: they sold about 800 CS-80s. Each of them would have come with an Owners / Users Manual – and Yamaha probably printed off extras for owners who lost them or whatever. Service manuals on the other hand did not come with a synth when it was new. They were deployed to the global network of Yamaha service centers and techs. There could be thousands of CS-80 service manuals floating around for the handful of CS-80s ever made. To test this theory see how many GX-1 service manuals are out there for the 10 or so examples of that synth they ever made.

I have SY-1 and CS20M/40M manuals and they both have covers in this charming 1970s mustand yellow.

Update July 1, 2021: Someone spent $3000 on a stand and the rare leg carrying case for a CS-80! Seems strange, but if you have a CS-80 these days and your value is pushing whatever you are brave enough to ask, you probably need these if your example didn’t come with them.

Yep – someone paid more for a set of legs than a CS-60 went for a few years back.
