So I turned on my system yesterday and after warming up for a couple/few minutes, I heard an oscillating sound through both speakers. I immediately turned off the amp and checked the seating of all of the tubes (the power tubes are a new set installed last week) and all of the connections in the system. Found no issues and no smell of smoke.
I then turned the volume all the way down (it had been at 9 o'clock) and turned the system back on. I heard nothing but the usual noise with my ear to the drivers and, as usual, nothing two feet away. I then turned up the volume knob and the oscillating sound appeared and increased as the gain was increased. I then immediately shut of the amp and system again.
Just this morning I took off the cover. Nothing burnt or obviously wrong, except for a fuse (B+ rail?) not fully seated. It was making contact at both ends however. Could this be the problem?
Could it be something else?
TIA
Follow Ups:
apparently. The loose fuse seems to have been the culprit.
Just remember: Loose fuses sink ships. Happy you found the problem. Had the fuse previously been pulled for some reason or is the holder bad?

Neither. I did move the amp to re-hang some GIK panels so perhaps then.
