Yamaha CS-10

” Classic 70’s mono synth in solid condition with all knobs, switches, jacks and LED’s working as intended.

This unit was recently serviced, with the power supply being recalibrated along with the VCO, VCF and VCA sections — in other words a full recalibration of the unit as per the original service manual.

The unit has been modified to operate at normal US wall voltage, not the 100V Japanese it was originally set for. This mod only involved attaching a different tap from the original transformer inside, as per the service manual.

Key action is smooth throughout full range of keys.” Click here to search for synths on eBay

“This is a great analog single oscillator monophonic synth. It is in used condition. Minor scratches on the hard shell carrying case but the synth functions beautifully (all knobs jacks and keys work). Original power cord still attached.” Click here to search for synths on eBay

“Up for sale is our Yamaha CS10 vintage monosynth.

The synth is in fully working condition, has been thoroughly tested.

All keys contact correctly, all knobs work as they should and are free of crackles, switches function correctly.

Cosmetic condition is excellent, with some minor marks and blemishes only.

It’s a 100v model so a step down transformer may be required depending on your location.”

“I’m the original owner of this CS-10, bought it in Japan in 1981. Still in good condition. Sounds great; rich tones – pure analog. All keys/knobs/sliders solid and working. Besides the organic sounds generated from the keyboard, I plugged my guitar and mic into it for very interesting sounds and ideas. Hate to see it go, but I haven’t used it in many years, and I’m downsizing – everything must go. ”

“This is a great small mono synth imported from Japan in the 1970s. It runs at Japan 100V but works totally fine in the US at 115/120VAC. I do have a step up transformer I will include for an extra $20 if you’d like.

Powers on and all keys produce sound. This is a vintage item and may need calibration or servicing to get back to factory specs and is sold AS-IS. ” Click here to search for synths on eBay

“Old “SnaggleTooth” has had it’s share of memories. Synth is complete, clean and smooth. I ran signal into it and have sequenced sounds out of it, many records have been done on this one. Love it to death, but priorities are different now, so this must go. Kenton Cv to Midi workls as expected, neither has been out side of the studio, so these are extremely clean.” Click here to search for synths on eBay
