Hi everyone, gigging guitarist seeks wisdom......
My TH30 quite randomly decides to stop producing sweet orange tone and emits a loud noise that sort of sounded like when you touch the end of your instrument cable, only worse. I plug into it a week later and it worked for an entire practice, then decides to cut out halfway into the first song of the next practice and does the same thing. I just plugged back into it and it did it again. No guitar signal is coming out at all. It just replaces my guitar with the horrible noise almost as if a fader knob is being turned up. It stops making the noise in standby, and starts right back up in full and half. It also does it in clean.
I have checked it with multiple guitars, instrument cables, cabinets, and speaker cables.
All 9 tubes are lit up...I don't know if that means much, but I just figured maybe it could help narrow down the culprit.
Any help would be greatly appreciated.
Thanks so much in advance!
i have ordered a matched set of pre and power amp tubes which will be here on weds!
Help!!!!

I will re-seat the power tubes and switch clean the inputs.
Don’t replace all the valves at once if you can avoid it, since it would be useful to know which is the faulty one - it will only be one - so you can keep the others as spares.
