“Vintage Yamaha CS70M for parts or repair. This is a classic synthesizer from the ’70’s. Here’s a description courtesy of Vintagesynth.com:
The CS70m is a great big powerful polyphonic analog synthesizer which belongs to Yamaha’s excellent line of CS series synthesizers. Fat sounds, cutting leads and bubbly basses, the CS70m has 6 voices of polyphony each supported by 2 oscillators for a total of 12 analog VCO’s! It’s got very flexible LFO, envelope and filter controls all of which sound really nice and smooth. The VCF (filter) has its own independent envelope control as well. Truly a lush sounding instrument that would please anyone looking for that J.M. Jarre or Tangerine Dream sound. Other features include a 4 track polyphonic sequencer, a 5 octave keyboard with aftertouch sensitivity and external magnetic data card memory storage. With only a slim 30 preset sounds that are mediocre, this is the kind of synthesizer that begs you to grab its knobs and start editing (that could possibly explain its big flashy knobs and buttons).
Condition: As you may have figured out from the pictures, this synth is sold for parts or repair. We’re cleaning out a storage area of our store and we discovered this. It powers up and produces some sounds and some functions seem to work-I’m not a keyboard guy so I didn’t check all functions. It’s missing some keys and some of the keys do not work. Cosmetics are fair at best-besides the missing keys it’s missing the end cap on the treble side and a couple of knobs on the sliders. The veneer is missing on the back panel and there’s lots of marks and dings on the wooden parts. ” Click here to visit listing on eBay
” Yamaha CS70M polyphonic synthesizer top-grade heyday of the Yamaha. Around the same time the company creates a recognized king of synths – the Yamaha CS80, which survived in working condition very little. However, the model CS70M is one of the few affordable ways to touch the legend and closer in sound to the flagship.
Yamaha CS70M synthesizer with a powerful analog sound and developed architecture and solution for a sound designer. Stable live in job, has the possibility of preserving sounds, and in contrast to the 80-th model weighs significantly less, does not overheat and does not swim on the line.
The tool provides already become classical sounds a-la Vangelis Blade Runner, and in the right hands many, many interesting things.” Click here to visit listing on eBay
The 2nd oscillator was never that great (always sounding). So I played it as a one osc synth mainly between 1991-1992. I gigged it once or twice.
After that it sat in the studio, switched off nearly the whole time apart from special occasions when I wanted to make Sci Fi sounds.
In 2010 I last played it. It was the same then (1 osc fine, the other one I didn’t bother with). However the last time it was switched on – the summer of 2015 – (apart from just now to test it again), the synth made a sound but failed to hold the pitch steady. It was like permanently having a slow sine wave applied to the pitch the whole time.
This time to test it for the sale I am hearing only white noise. In other respects the synth is responding to touch.
The buttons and pots are all excellent, for example. Most of the LEDs light up. The pitch and mod wheels are in wonderful condition and have that heavy return to center feel to them which adds a touch of class to this already high end and rare synth.” Click here to visit listing on eBay
Der CS-70M ist einer der besten analogen Synths, die ich kenne. Eigentlich ist es sogar der Beste. Ich hatte Memorymoog und SunSyn und die beiden sind auch der Wahnsinn, aber der CS-70M hat diesen berüchtigten CS Sound und eine wundervoll einfache Bedienung und ist perfekt designt. Und mit den 2*15 Speicherplätzen und den Kombinationen daraus hat man ein unglaublich starkes und flexibles Vintage Gerät.
Der Zustand ist einwandfrei. Der Vorbesitzer ließ ihn ca 2013 durchchecken, die Elkos austauschen und Midi einbauen. Er läuft wunderbar und hat äußerlich nur wenige Blessuren. Am Holzfurnier sind einpaar Splitter abgegangen und die schwarze Oberfläche hat einpaar überschaubare Kratzer.
Solche Geräte sollte man tunlichst nicht versenden. Es wäre also gut, wenn man es abholen kommt. Ich würde es bei Bedarf trotzdem gut verpacken und versenden, aber dann schließe ich jegliche Gewährleistung aus.

One of the rarest analogue synths ever. 12 VCOs, stereo output – real fat sound! Pretty close to CS-80, but much stable and autotunable.
In fully working order and good cosmetic condition.
Pots and switches moves without any cracks or noises. The tune is fine. Patch memory function also works as should.
No dust or dirt inside.
All electrolytic capacitors in power supply was replaced and PSU was precisely adjusted after that.
Fully serviced and ready for years of problem-free use!
As you can see in photos, battery cover has lost some paintwork, because of old battery leakage. I have changed battery holder to the exactly same, but new and clean. ( if you need the old battery holder, I can included it.)
Socket for power cable was replaced to the standard type, that you can find on any modern PC, for example. If you want, I can place original socket back, and give you original cable, but if you loose or broke it, I am sure that it will be pain to find a replacement because of it rareness.
I didn’t check properly magnetic card reader, but it was tested with paper strips (it soaks it and try to read/write).
Standard US-power cable included.
Two Yamaha’s trigger pedals and pair of shielded silver wires as a gift.” Click here to visit listing on eBay
“You are bidding Yamaha CS-70M 6 voice analog synthesizer (CS80 has 7 voices). Unit is in very good shape for 40 year old synth-see pictures. The synth came from PRO studio.As far as I know the synth has been served couple years ago. I tested unit by myself and I have to say next: absolutely everything seems to be fine, I tried every single slider and every button and they all work including little lights on buttons. Good and stable turning, autotune works fine, no any overheating(very common for CS80, 70, 60, 50) I have to say it’s phenominal synth, sounds exactly like CS80+ 4 track sequencer and better aftertouch + split, unison. Where is no discoloration on keys, all white and clean and all keys work fine. I also unscrewed the synth, she looks very impressive inside! see pictures.” Click here to visit listing on eBay
