New to this board kinda and due to my own circumstances need to try to fix my amp by myself, hopefully with some help,advice and knowledge from the posters here. So if any of you people can offer some assistance and instruction it would be greatly appreciated. My problem as I wrote in the title is one of my power tubes is now over heating, I just got this amp, the seller said it was just gone through and when I first pluged it in and turned it on the power light lit but the tubes did not power up at all. That was a loose wire from the power light to the first power tube socket. I reconnected that and all seemed fine for about two hours. Brought the amp home went to practice and got a loud noise like static happening when I turned it on. Shut it down turned it back on worked ok for a little while, started with the noise again. I can hear what sounds like a faint tremelo regeneration in the background when no signal is being sent. The tube isn't the problem, I tried two others and get the same over heating, all glow a bright orange while the other three tubes are fine. Anybody seen this before? And is this something that a new to amp repair person could/should attemp to fix?
