Early minimoog osc 3 dead

Post by MHAUGHEY » Thu Jan 16, 2020 6:31 pm

I have a Minimoog D with early oscillator board.
Osc 3 not oscillating, no sawtooth on neg side of C8 , just sitting at 0v.
I have schematic + theory of operation writeup, a dmm and a scope, where should I start? Any common component failures?
Osc 1 and 2 are working, so should be a good comparison for voltages and waveforms.
