Yamaha CS-50


via this auction

"Unit is in superb condition. There's a few nicks and scratches on the unit but this is to be expected 40 yr+ machine. I've had the unit completely done over by my synth tech in Feb of 2019. Work as followed:

-Replacement of all the electrolytic caps in the power supply -Op amp replacement in the square wave LFO
-Re-calibration of the Brilliance Fader. Item was removed, given a good cleaning and mechanical lubrication on the bench, and wired it back in.
-Fllushed the Modulation Fader that was scratchy, and did the same for the master volume and high/low level switch in the back."
