"I need your knowledge! I've got a triple rectifier, I replaced all but the preamp tubes. When the amp is just idling I can hear the tubes (or something) jingle. Sometimes louder, sometimes quieter. Still happens with no guitar plugged in, happens in stand-by and on. What's goin on?! Normal? Catastrophic?"

Is it having an effect on the sound coming out of the amp? Any hum, buzz, “jingle” to the tone?
