OK guys, I'd like to report an issue with my amp. As of 5 minutes ago, every time I turn it on and turn the volume past 0, instead of my lovely guitar sound I get something that sounds like radio static. A lot of radio static. I'll post a sound clip soon but in the meantime - HELP. Oh, and there are no obvious issues with the power tubes as far as I can tell (although they did just start making some faint popping sounds). I just got it back from the repair shop and I need the amp for a weeklong workshop I'm doing starting saturday.

It's occured to me that it might be the fuse, anyone have any idea?

one of the best, educated and logical posts I've ever seen on UG in the Pit. Well done good sir.
Something similar occurs to my amp (it's a solid state), it catches the radio signals from the cops and cabs in the street hahaha, but I don't know why
What did the repair shop do for a fix? (what was the problem before)

Check to see if those are actually the same tubes you had before.
I have heard of some "repairs" actually involve a sneaky switch with bad tubes.
