Just joking, I'm not pulling my hair out anymore, just thought it'd be a cool title LOL. For those that saw my last thread, I just bought a new amp, finally just pulled the trigger. Anyway, came in under budget, and thought about getting some upgraded tubes to go in it. Its a JCA20H, jet city. Any suggestions, I'm thinking of going with JJs, heard a demo of stock vs. JJs and they sounded excellent to my ears. Other recommendations are welcome, probably NOS stuff is out of my price range, but will check out anything. What about BIAS? If I order some drop in JJs, do I need to have this thing rebiased. Its new, so? I'd probably have to take it somewhere because I am a little leary of trying this myself, not replacing the tubes, but the bias part. Thanks guys in advance.
