RE: How did you narrow the problem down to couling cap(s)?

Good question, FenderLover. I am not sure it is the coupling caps at all. Bad answer, I know, yet I don't have the proper equipment to test, and this is just an educated guess.

Idle bias was at 230mA, although now reads 0mA no matter where the dial is adjusted. The bias output now also reads ~24mV and ~16 Ohms no matter where the adjustment dial is placed, whereas typically the mV can be adjusted.

Thanks much for any insights on how to troubleshoot!

Kind regards,
Michael
