I need to re-tube both of my Alamo amps, Montclair Reverb, 1x12 combos. I had been using the EH 6V6, but it's been years since I've bought any... and it appears that it's not the same tube that it once was?? I tried some JJ tubes in it, but they don't sound right in this amp at all. I basically use the amps at 90% volume all the time, and the JJs just don't compress in a good way in this amp. What other 6V6s should I be trying? I use these amps almost at full-tilt, and use my guitar volume knob and a Fulltone Fatboost to push them into strong saturation. Greenback in one, and a Eminence Screamin' Eagle in the other.
