"A beautiful duophonic synthesizer. This is the earlier model circa 1972 with a CM3 input jack - later models were changed to a SEQ input. This instrument is in good cosmetic condition for its age and it sounds fantastic.

This was first owned by San Diego State University, where I presume it had the cinch jones connector added and was etched and stickered. That connector is producing 15v at pin 5, -15v at pin 11 and is grounded at pin 4.

Any known issues are few: the pilot light is intermittent - flickers on/off and will stay off periodically. The top right corner of the case is separated at the joint but it is sturdy (pictured). There is a missing wood screw in the interior of the keyboard case (pictured). Knicks and dings here and there on the case and face plate, naturally - but really not bad.

All electrolytic capacitors were replaced in January 2019. Included is the non-destructive BellTone 1v/Octave mod kit which I never installed (pictured). The handle is an after-market replacement (not original)."
