Dan and PB, I talked with Jay at Eurotubes today about this thread, and he said they'd be happy to talk with you guys more about what they've experienced in terms of failures with BH amps. Their number is 503-659-7401, if you guys want to get in touch. Dying to get my Stereomour back up and running, so I'll be picking up some other tubes in the mean time, but it would be great to better understand what, if any, issue there is with the JJ's for the next time I feel the itch to do some tube rolling. Thanks for being willing to jump in on this conversation!
