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.

My Roland RS-09 on eBay

I’m moving and in addition to not wanting to move a bunch of keyboards, I could use a little cash so I put my Japanese market RS-09 version 3 ‘Organ and Strings’ synthesizer on eBay.  Basic ‘It works and sounds great’ estate sale find descriptions after plugging in headphones and touching a few keys do not apply here.

This unit has been serviced by a tech to fix a faint continuous C# (couple of capacitors) and stubbornly noisy volume pot (new pot).  Since servicing it has been used on several recording sketches and performed flawlessly.

Clean, attractive and ready to make music.  Buttons and slider caps are the same as Jupiter 8.
