Circuit Overview:
     A divide down string ensemble synth with 3 VCO's and a sweet sounding phaser with control. High and low EQ knob and some great preset tone filters. Individual tune controls like Lambda. Might be viewed as the predesessor of Lambda I suppose.

Service Tips:
     Use of a headphone amp recommended in tracking missing/distorted notes in all divide down type circuits like this. Get diagram of chip in question and listen to notes that are present and missing/distorted and you should be able to find bad chip.

I probably have some parts for these. No clue who else would except vintage planet.
