Ok guys, for starters I have an old Fender PA100 amp. I read somewhere a while ago that it is safer to completely bypass the ground switch and switch to a 3-wire plug. However, this amp already has a 3-prong plug. Here's the schematic: https://schematicheavencom.secure.powweb.com/fenderamps/pa100.pdf When I opened this amp up, the grounding switch has already been disconnected, but the ground pin on the power cord itself has been broken off. My question: should I re-hook up the ground switch, or leave it out of the picture? I already plan on replacing the power cord.
