Hi, Gang: Well, I got new JJ tubes for my Buster 200 1X15 combo and managed to get the amp section out and replace the tubes. Then I managed to get the whole thing back together (if you have not picked up on the fact that I am a tard when it comes to this stuff, you will soon). I fired it up and it sounded a lot better. BUT, one of the 6L6s is not glowing. AND, there seems to be a kind of blooming metallic sound behind the signal. It's in the background so it's not that bad. I need advice about what all this means before I dump this whole thing off an a tech for $$$. Anyone?
