Default Ampzilla Hums! - Troubleshooting advice, please.

Hi, Phil.

I'm still not sure from your response whether the hum is coming

from one or
both speakers, or a mechanical noise from the amp chassis

itself.
If it's a mechanical noise, one can use a listening instrument

such as a
medium length screwdriver, and physically touch it to a part of

the chassis
while holding the handle to your ear. Works like a stethoscope,

and I find
this useful to help isolate mech noises.

I am sorry if I was unclear. The hum is from the amp itself.
Also, the meter lamps have stopped working.
