Hi!
Yesterday we worked with Marvel on Structure Mod (detail soon) and found out that Sovtek LPS in V1 (which I like in that position) rings and dings as hell when we knocked the tube itself, but also the chassis or front panel. We thought that the tube went microphonic and replaced it with known good non-microphhonic tube but the issue remained. EVERY tube we tried here (which were known as good and non-microphonic) gave such symptom. Do any of You has similar experience? I mean - when You knock Your amp at the front near V1 tube when on Red Channel quite cranked, does it produce a short bell-like dings (for lack of better word)?
Regards, Andy
