Tube amp help. Way too much buzzing! (1 Viewer)

[Kev Bones]

I have a peavey valve king head. Recently there's been a really loud fuzzy buzz coming from it even when the volume is completely down and nothing plugged into the input. It's definitely not the speaker cable. Anyone have any ideas for a quick fix? Do the tubes need replaced? I don't have any other problems besides this buzz.

The most likely cause is a dodgy power valve, it's probably not the preamp valves as the volume does not affect the level of buzz.
Try removing the power valves and see does the noise go away.
If it does it's time to get a new set of power valves and continue rockin'.
