I think this might be pretty normal for a tube amp or any amp for that matter. But, during shows my Dual Rectifier gets left on for about three to four hours at a time (both idle and working). After about two to two and a half hours I get a little bit of white noise coming out of the speakers. It's not really noticable unless your listening for it, but it's there where it didn't exist in the first couple hours. I'm wondering if maybe the tubes are getting too hot or possibly they are starting to go bad.
White noise after a couple hours.
