TH30 intermittent cut-out
Posted: Mon Aug 27, 2018 8:37 am
My second hand TH30 quite randomly decides to emit a loud noise that sort of sounded like when you touch the end of your instrument cable, only worse. I plug into it later and it works for sometimes hours, sometimes just minutes, then decides to cut out 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 four tubes are lit up...they are stock tubes and will be old. A matched set of all 7 tubes are on the way...
Any help would be greatly appreciated.
Thanks so much in advance!
