I have an 80s model peavy tko 65 bass amplifier. there is some kind of short, the comp. light comes on and it just buzzes... just happened *** i was playing the other day, slapped it and it went away. came back and all i get is a buzz/hum. when i press on the front amplifier face anywhere the green comp. light goes off and it works fine.. when i release pressure it buzzes again. I took speaker out, inserted a different one, same thing, so that rules out the speaker... pulled the amp out and checked the fuse, it was fine... saw no loose solders anywhere.. what could this be?

probably your power is too short, increase your gauge wire, and your ground wire of the amplifier has to be shortly as possible, and the positive has to be enough to support peak power, you can also put a big capacitor on the positive wire to give some more power while the bass peak.
