Okay, forgive my total and complete ignorance when it comes to electronics.
I have a Peavey Classic 60 power amp, worked before I brought it in for service (new tubes).
Got it back from the local tech, and one of the tubes started glowing red hot to an extreme- I turned everything off and got a RMA on the matched tube set.
Put the new tube set in (Groove tubes, supposedly no bias needed for the same power rating). And immediately the same socket's tube began to glow like a red lightbulb, a strong hum came from the speaker, and then the fuse popped. All in about 5 seconds.
I can't imagine I had two bad tube sets in a row, I also read that not all the socket's contacts may not be seated properly.
I don't want to bring the unit back to the tech who serviced it, he either missed something or charged me for work he didn't do. Claimed he checked everything out before the retube and bias.
Any ideas what it could be? Thanks for your help!
