Hi all. My Randall RM50 has recently started squealing if I boost the preamp gain or level up too high regardless of whether or not there's anything plugged in to it. Is this tube microphonics? If you tap on the input jack it can be heard through the speaker and the reverb tank. Thanks.

Fail

I expected a tale of "The Ghost Who Just Learned Pinch Harmonics".
