Thanks for the kind words, Mike. I get it now, it's all Richard Gray's fault. I was going to suggest that if the AC line from your audio to the service panel is 12/2 Romex, you could install a 20A breaker. But in light of the condition of your breakers you could use a new panel. At the very least, have a licensed electrician inspect your mains and replace the breakers if the panel is up to code.
I had all new electrical installed two years ago due to corrosion on the meter and outside line.
