I let a friend jam on my amp for a few, i left him alone. he decided to turn my amp off, then decided to play some more. he turned both stand by off and turned the power past off too variac. then he turned it on the same way, both switches together. now theres no sound. The power light does not come on. the fan isnt on. the power tubes are lightly lit. 5 of the preamp tubes are dimmly lit and 2 have no sign of life. prevously it would click and cut out for a moment, when on channel 3. i was assuming that it was probably the footswitch cord.
i checked the fuse. changed all the tubes to known good tubes. turned every knob, flicked every switch. plugged and unplugged every jack/ footswitch. i checked screen grid resistors. looked over the whole board with a magnifying glass for cracks, burns, loose or bad solder connections etc...
its no longer under warrenty
Does anybody know what it could be or have had a similar problem?
