SOURCE: problems with amp switch
get an ohm meter and test to a known ground, like the sleeve on the guitar cable. If neither is grounded, it doesn't matter. If one is grounded, take it to neutral.
Best bet, get the same switch and put it in exactly like the one you have.

Here is a troubleshooting hint:
Put an incandescent lamp in series with the hot side of the power cord. This acts as a resetable fuse while troubleshooting so you don't blow fuses.
Schematics are hard to come by, but power supplies are easy to trace the circuitry.
Check filter caps and the diodes and THEN look for hot (temp) IC's and transistors.
