I have a very nice CS50 that has the problem I described in my last email (functioning but very quiet saw and ramp waves in VCO across all voices, with working PWM,PW,HPF,LPF). I'm looking to get $900 for it. Would make a great parts machine if one was so inclined as all four voices tune up fine. Includes lid and legs and a second CS50 chassis.
I'm in SF bay area California
