Sequential Circuits Prophet 600 Project Machine

“NOT WORKING! Will not turn on. I have owned this synth since it was new for my home studio. See pics for superb cosmetic condition. Never gigged, never left it’s climate-controlled, smoke free environment. I do not know what the issue is, but before it went into storage I tested it and found several keys did not play. This was always played thru MIDI from my DX7, so I didn’t notice this before that. Hopefully someone familiar with these can bring it back to life-these instruments have a wonderfully rich sound and deserve to be played.

It will ship with the original Owner’s Manual and a HYBRID flight case that I had made for it when new.

The Prophet-600 is a 6-voice polyphonic analog synthesizer with a 5-octave, 61-note (C-C) keyboard. Each voice consists of two VCOs, two VCFs, and two VCAs. Each of these components has its own independent ADSR envelope. Each Prophet-600 voice uses 2 sets of Curtis Chips for its architecture.”
