So I have a Randall RG50TC and just recently it started making noises, first it was randomly when I played, then it was when I just turned it on, and then it stopped for a few minutes then just exploded into this large growling buzz that is one volume no matter what my volume is and none of the tubes seem broken and all the electronics look fine, so I have no clue, does anyone have any idea?
Obsession! Obsessive! Obsessed! Abscess!
I think it might be the tubes. That happens sometimes when a pre-amp tube goes micophonic.

This is terrible advice. Even worse than the useless dry, sarcastic comment I made.

I'm too old for the Jim Morrison look now. When I was gigging I had a fine arse.
If the volume makes no difference I'm going to say it's probably the power tubes.
