I would rather post in the data east board but.. I'm not verified.
Question: Is the -12v coming off the power supply used for anything else besides the sound board?
My eyeballs are not seeing anything. I'm worried because the -12v is really bad and what else might it have effected besides the digital sound.
The amps on the sound board are the only consumers of that -12VDC.
The -12V is sourced directly from the bridge.
