Odyssey, board C
Board C was the least problematic board of the three.. Only A2 seemed to be leaking VCA control voltage to the audio output no matter how the common voltage rejection (CVR) was calibrated, so I gave it the same socket replacement treatment as the CA3080 on Board B. Other than that, I just replaced the parts on the audio path and the board was sorted out! These replaced parts were R1-R3, R5, R13, R16-R22, R28, R65, C1, C3, C5, C6 and C9 – C12.
Now then, about that CV issue on board A..
