GU-12 Tragedy! Help!
#8
Ok so I went ahead and soldered the wires directly to the circuit board and replaced the broken power tubes. Initially the amp worked great. The tremolo and reverb sounded wonderful. It was clean and clear and had that great amp overdrive. I played it for like 2 hours that night and it sounded great. The next day at lunch i came home and started playing. Again it sounded wonderful. About a hour into playing it mysteriously lost the reverb, then the tremolo and then completely shut off. I have not been able to turn it on again at all. The pilot light will light up but absolutely no sound comes from the amplifier now. no hum no hiss no nothing. The tubes are not glowing at all. What could that mean? Did the output transformer crap out on me?

Here's a picture of the other side of the board. Everything looks in order. The bigger cap looks like it's partially dried out but still working I believe
