As the title says, normal mode is a little loud when cranked. Low volume mode is ridiculously loud (like it always was) at the same volume. The amp was working fine for a couple of years after a bought it used, then one day at practice it didn't work right any more. :-)
I figure I have a bad tube. Any tips on identifying the problem? I'd like to avoid having to take it to a repair shop. I have an authorized service center in Denver, but if I can swap some glass I'd love to save the drive time and the moolah.
Thanks!
