Well, it finally happened - I plugged in a module backward, and now my favorite VCA module is acting up. Visual inspection of the board is unremarkable (no abnormal/fried looking ICs). Functionally, it doesn’t pass audio or CV. The LEDs all go from off straight to Red.
I’m really unpracticed at reading schematics - can anyone please help guide me along the path to check for faults? The package size of the CoolAudio ICs is easy enough to probe, but if anyone has guidance on how to probe the tiny pitch ICs without shorting them, I’m all ears.
Thanks in advance!
