Question about Musical Instruments
I may have, inadvertently, left it on. Now it shows no sign of life. Fuses look good. Burned out power supply? Any help greatly appreciated.
Without power to the unit no sound should be generated. Make sure there are no other connections.
MAYBE you have a wall transformer behind it that is buzzing. MANY wall transformers develop buzz.
Another source is flourescent lights and even some of the low voltage halogens have noisy transformers in the base.

I had checked the fuse for the heater circuit and found that while it was testing on a low ohm check meter - it was not sufficiently handling the
full demand of the circuit - I put a bypass on the fuse and found the problem. The fuse appears to have been previously replaced with
a type not original - the original was a ceramic case fuse 10A.
I appear to be operational
