ok well i have a 200 watt fender deluxe reverb amp and i plugged my guitar into it nd no sound comes out at all wats so ever. the power tube things still heat up nd everything but no sound come out of the amp. is it the tubes or the speakers? help me out here
Just because the tubes glow doesnt mean they are good. if the guitar and cable works on another amp then the tubes is a good place to start.
It could be

bad tubes
burnt resistor
blown transformer
dirty tube socket
bad grounding somewhere in the amp
Over biased tubes
under biased tube
bad coupling cap
back filter caps
dead pot
broken wire
or a short

Thats what I can think of off the top of my head. Try changing tubes and if that doesn't work you need to take your amp to a tech and see what they tell you.
