Whats up folks. Some of you guys might remember me. Anywho! My 1987 have just flat out stopped making sounds? From the other night when I was playing, and merely turned the amp off, It died overnight while attempting to start it the next morning. Light comes on, all tubes are glowing and warm to the touch, just no sound at all? tried removing and reinserting tubes, tried changing cables, checked fuses...... What gives? and as a bonus question. Who does great Marshall work in Los Angeles?
