Thanks for the reply Steve. Actually, the tubes DO glow red if they are allowed to heat up, but after the first time I saw that happen, I don't think I let it go that far again. That happened with the original (sylvannia?) tubes. I replaced both the power tubes and the pre-amp tube with the proper groove tubes and they will do the same thing. No other problem with the amp. Speakers are the original 2 X 12's in the combo, switch on 8 ohms. 20 years ago when I use to gig with it I played blues/rock and liked the low power overdrive sound, and it was plenty loud. Now I want to try it with an acoustic rig on cleaner high power. I think I'll just take it to a shop, have it checked up and biased, maybe they'll find the problem. I'll let you know.
