James…..Total overhaul.
Ring Modulator & VCA – replace ICs, Transistors &
rewire to 6V. Triple Waveshaper – complete rewire of I/O connections and pots. Gates &
Comparator – rewire for 6V. Smooth & Stepped Function Generator – traced to bad joint.
Processor – Rewire to panel & replace burnt pot. Sequencer – Replace 4051 IC. Variable Q
VCF – Remove 3x Gain Cell’s & evaluate in test circuit (faulty). PSU – Remove 4th Rail providing
wrong voltage to missing 6V rail. Add DC/DC Converter for 12V to 6V.
Build 3 replacement Gain Cells, Match Transistors . Fully Install 6V Rail.
