Default overvoltage on audio circuits

Maybe, but if the supply is producing 21V, it might be producing noise too.




** FYI:

Just about the dumbest thing any console designer can do is fill up the modules with rail bypassing electros ( tants or otherwise) without series resistors.

Doing that injects wide band noise from the regulated PSU directly into the ground pattern and ribbon cabling - millivolts of the evil stuff.

Seen it done.
