My Fender Twin is emitting a sound (birdlike or radio chatter interference-not loud) sound. The "idiot lights" in the back light green and everything sounds fine when playing the guitar. I turned all lights, electric devices I could to eliminate any possible interference. The sound is intermittent and lasts maybe 5-10 seconds. I spoke to someone at a large music store (repair area) and they said it could be one or more of the 12AX7 preamp tubes going microphonic. The Amp is just a year old played maybe ten hours a week at volume 2-3. I thought the power tubes wear out faster then the preamp tubes. Anybody have ANY ideas...?
