SOURCE: peavey classic 50/50 keeps blowing fuses.

Rob,

I have a classic 50/50 as well and re-tubed it with JJ el84s, vintage teslas and mullard 12at7s. As long as you replaced it with EL84s, I can't imagine that the output would be increased enough to damage the OT. When I got my 6505 Combo, one of the 6L6s was bad, and it kept blowing fuses and howling like a banshee. I would think that an OT problem would result in a significant loss of output...or none at all. I've gotten DOA tubes from a few places. I would suggest swapping each tube out 1 by 1, until you find it...if that is indeed the problem...before you pay the cash to have it worked on.

SOURCE: peavey classic 30, new tubes and PT with absolutely no sound

I'm not sure what "PT" is , but the heater voltage is separate from the other voltages required for this unit to function properly. Please note that with tube systems, there are voltages in the 300-400V range that can cause injury. If you do not have experience with tube based electronics, I would suggest that you bring this to a service center for repair.

Please update this with what you mean by "PT" and we'll continue from there.

Thanks,
Dan

SOURCE: Hi, Peavey Classic Guitar amp , Has NO SOUND

Hi Mike,

If you switch on the amplifier, do you hear nothing at all?
Or do you hear low level noise or hum out of the speaker?
Don't know if you're technician.
If the tubes are glowing, you can measure the high voltage.
Check also fuse 3 and 4, thats the neg. voltage -27V and -14V.


regards,
Gerard

I have a peavey classic 20 guitar amp that works as normal when switching on but after a couple of minutes the power amp tubes (EL84's) just switch off. What could the problem be?


What do you mean they "switch off"??? If the heaters in all the tubes go out, check the fuse for the heaters, F2 and its fuse clips/holder.

There really is nothing in the circuit to make them "switch off"

If the heaters in the EL34's "switch off", the other tubes should go out as well.
