” YAMAHA CS 20M JUST SERVICED BY TEFI VINTAGE LAB.” Link
IF YOU ARE LOOKING AT THIS I’M SURE YOU KNOW WHAT IT IS BUT IF YOU WANT SOME INFO PLEASE CHECK AT VINTAGE SYNTH EXPLORER.
THE SYNTH IS IN EXCELLENT CONDITION, THE SIDE PANELS ARE PERFECT THE CASE HAS PROTECTED IT VERY WELL. THERE ARE A COUPLE PATCHES OF RUST (PLEASE CHECK PHOTOS) ON THE FACE OF THE SYNTH, BUT IT’S NOT MAJORLY OFFENSIVE AT ALL, I’M SURE YOU APPRECIATE THE AGE OF THIS SYNTH, YOU HAVE TO EXPECT A LITTLE WARE. IT CERTAINLY DOESN’T LOOK NEW BUT IT’S IN GREAT SHAPE FOR IT’S AGE.
THE SYNTH IS WORKING PERFECTLY AND THE MEMORY STILL HOLDS. I DIDN’T HEAR ANY SCRATCHY POTS WHEN CHECKING.
THIS MACHINE IS 100V 50/60HZ, DEPENDING ON WHICH COUNTRY YOU ARE LIVING IN YOU MAY NEED A POWER CONVERTER (READILY AVAILABLE AND FAIRLY CHEAP). IT’S WORTH GETTING A DECENT POWER CONVERTER ANYWAY SO YOU CAN USE OTHER QUALITY JAPANESE SYNTHESIZERS EFFECT PROCESSORS ETC.” Link
I have got another big project coming so need to work on it for several months now and there is no time to finish this guy.
The unit appears to be in good visual condition (both internal and external). The only small issue is that two red LEDs are missing from the patch panel (check picture).
It is sold AS IS.
This machine needs repairs so based on that I won’t promise you any refund or returns. ” Link

“Up for sale, very rare Yamaha CS-20M analogue synthesizer. As you can see from the pictures is in excellent condition. Has been serviced professionally, all electrolytic capacitors have been replaced with high quality Nichicon caps, power supply rebuild and calibrated, all series 4000 IC that been known to fail replaced with new ones, new battery installed so you can save your patches, everything works flawlessly. Balanced out audio, one of the best sounding from the CS series. Tons of modulation capabilities. Used in my smoke free home studio.” Auction ended. Click here to browse on eBay.
This is essentially a CS40m without the Ring Modulator, The PWM Function routing and 8 less keys.
For those who are wondering… the “M” series CS synths do NOT sound like the standard CS’s like the 10,15,30 etc.
The m’s sound more like a Moog than any other. Smoother and to me, sits better in a mix.
These 20m’s are amazing for creating some unique sounds. Basses and leads for sure, but the modulation routing is very deep, Every VCO, the Filter and the EG has it’s own modulation type selector and amount. so you can essentially have a Sine wave, a saw wave, a S/H and a Tri wave going at the same time!!!! All clocked to the internal LFO Speed!
Everything works, It keeps pitch, there are a few pots that are a little scratchy, but just need cleaning.
Also has CV I/O!
And… yes it stores patches… internal battery was replaced last year.
These rarely come up on the used market. if you are looking for that CS70, CS40 sound, this is your chance to get it. ” Auction ended. Click here to browse on eBay.
PLEASE READ CAREFULLY BEFORE BIDDING
This synth is a classic and works well in its current condition, but will require some repair to work perfectly.
* Almost Fully Functional. Known Problems:
o Envelope Relases do not engage. Notes end when key is lifted.
o “GL+” mod settings work reverse on Oscillators — all other mod settings including “GL-” work as they should
o Unit must warm up for a bit to play consistenly — leave it powered up for 30 to 45 minutes and it plays wonderfully…upon initial start up, however, there is scratchy/intermittent audio– this is probably an old capacitor issue, but you will have to repair this if you desire
o Load/Store LEDs are always illumnated — no impact to function
* All original knobs sliders — none missing
* Good condition — no major scratches or breakage (minor on corners)
* Includes Manual (original, not a copy)
* Includes ORIGINAL box
* Good free knob / slider operation” Auction ended. Click here to browse on eBay.

I had it looked over by a tech last week and while the synth is fully functional and ready to go, the user presets memory isn’t storing. The tech said this function may come back over time with use and is a minor issue. I’m sure many of you never had memory presets on your analog synths so it isn’t like you will miss the function. There’s another way you can store presets – on tape; you can load the preset data (non-audio) to a cassette tape. The sustain slider cap is broken off (included) but this does not affect the function of the sustain. There are minor scuffs here and there, all pictured.
The synth works perfect and sounds fantastic! All the knobs and sliders work perfect. The CV Gate function works (really cool), (used my korg kr 55 for that). This auction comes with a photo-copied owner’s manual. ” Auction ended. Click here to browse on eBay.

“Up for auction is one Yamaha CS-20m synthesizer from 1979 in great condition!! The synth works great and sounds fantastic. Unlike some other synths of the era, you can store up to eight presets right on the board, which is AMAZING for an analog synth. Sure helps when you spent a lot of time dialing in a cool sound and want to retain it for later use. I’ve tested the memory preset buttons and all the knobs and sliders. The CV Gate function works (really cool), (used my korg kr 55 for that). Did not test the tape storage function but see no reason why that shouldn’t work as well, the synth is in great condition. The two very minor issues are: the LED light on preset #5 is not working, but this does not affect the ability to save a preset on button five and the sustain slider cap is broken off, but this does not affect the function of the sustain, although you may want to replace the slider if you want to put the slider cap back on. I am selling this baby because I don’t use it very much and need to raise money for a car. ” Auction ended. Click here to browse on eBay.
“All keys are in good shape and have been removed and cleaned. All pivots lithium lubricated. Power supply fully recapped with Xicon capacitors and voltages adjusted. All pots cleaned, no noisy audio path. The VCO’s and pitch wheel have been carefully scaled so please leave them alone. Memory storage works fine. Did not test the cassette patch download/upload interface but no reason to think it would not work as everything else does. Someone left batteries in the holder underneath which corroded so it has a new 2xAA holder. The corrosion was not kind to the cover plate, but that and the holder was the only casualty of that oversight by someone.
There are a few nicks on the wood, but there is one nasty scratch, and one corner is dented as shown in the photos. Other than that, it’s in surprisingly good shape as the CS series wood panels didn’t take road abuse very well (I toured with a new CS-40M back in the day). Happy to send some close-ups if you wish. Honestly, the graphics and paint are in remarkably fine shape over the entire synth (other than the scratch, not done by me), as are the knobs and sliders. It really is a fine specimen in general.
And it sounds great!!! Ballsy, synthy goodness. Would love to keep it but I just can’t justify it with a recent Prophet purchase and the wife’s reaction to same. No power cord, but it’s just the usual 3-pin variety found on every computer and monitor ever made. Owner’s and tech manuals readily available on the web, will send you what I downloaded and printed out with the unit. ” Auction ended. Click here to browse on eBay.
Technisch zeigt das Gerät beim einschalten leider keine Funktion, gehörte meinem Bruder der ausgezogen ist und ich kenne mich mit dem Gerät nicht aus
Optisch sieht das Keybord (müsste mindestens ca. 30 Jahre alt sein) aber noch recht gut aus, etwas Staub und Schmutz hat sich am Bedienfeld angesammelt
Der Zustand ist dennoch gebraucht und der Verkauf ist als defekt
Habe aber ein paar Foto’s gemacht ” Auction ended. Click here to browse on eBay.

Ich lege ihm ein neues Outputkabel auf 6,3mm Klinke dazu (3m).
Stromkabel ist dabei.
Er hat einen brillianten Klang mit enormen Druck!
Äußerlich ist er für sein Alter in einem recht guten Zustand. Leider hat er ein paar kleine Lackplatzer die etwas Rost gefangen haben in der nähe des Pitch- und Modulationsrad.
Mit dem Erwerb dieses Synthesizers ist noch ein Transportkoffer in dem er geliefert wird beinhaltet.
Versand ist möglich, dennoch rate ich zu einer Abholung. Versandkosten variieren je nach Strecke, weil er sehr schwer und groß ist (35kg mit Koffer).
Ich wünsche viel Spaß beim Bieten.” Auction ended. Click here to browse on eBay.
“One of the Yamaha CS series this one in VG+ condition with a few scratches especially on bottom front panel cosmetics are excellent works perfect. Local pick-up in Los Angeles CA area preferred, weighs A LOT.” Auction ended. Click here to browse on eBay.
“The only minor damage is a small scuff on the corners of the woodgrain and a small dent on one of the inputs in the rear of the machince (both can be seen in the pictures and neither affects the playability of the instrument). If you are looking for an instrument that you can plug in and use and look cool while doing so, this is your synth.” Auction ended. Click here to browse on eBay.
