I recently picked up a Trace Elliot GP12 SMX head. The amp was fine the first few practices, then all of a sudden in the middle of the set at my first show, the power cut. The power strip it was plugged into was fine since my other rack units were still on and working and there was no smoke or funny smell. The amp simply did not turn on, no lights or anything. I figured it was just a blown power fuse, but when I opened it up I could not find any spot for a fuse. The capacitors look fine and all the connections seem pretty solid. Does anyone have any idea what the problem could be and how severe it may be?
