I have a noise/vibration/rattle (?) that eminates from my Germino Masonette when I hit the lower frequencies. I have narrowed it down to one of the power tubes. When I pluck a low note, reach behind and hold that tube, the noise stops, but when I let go, it appears again. I have tried readjusting the tube to make sure it seated correctly. So far no luck. Is something loose? Is it the tube socket? How do I fix this annoyance that is ruining my tone?
Also, I've noticed amp hiss louder than normal, even without any pedals connected - guitar straight into amp. Any suggestions to troubleshoot? Just a slightly microphonic pre-amp tube?
Thanks...
