Replacing 2 prong on old LP Jr amp...question


Put your Rock Face on!
Does it matter which prong the hot and ground are on? Is the hot normally hooked to the switch or the fuse? Sorry for the newbie question, I just don't want to blow anything up on this vintage amp.


on those old amps what I like to do is re-wire them slightly. I'll go wall-->hot (black) to fuse-->fuse to switch-->switch to PT primary, then wire the neutral (white) --> to the other PT primary. Then find a bolt close to the power tube cathode ground point (or even the power tube cathode point itself) to hook up the green earth ground connection (soldered preferably). And then I use a separate, fender-style, strain relief on the new cord screwed to the cab to be doubly safe. My 2¢...
