A little update. I received a call from the tube seller that I returned the tubes to. Same fellow. This time he was polite and fair. He tested all 8 tubes and infact felt non of the tubes meet his level of quality. He said there were some things that didn’t hold up well with extra extensive testing. We worked out a deal that I’m happy with for tungsol 34b tubes in place of the JJ tubes. I have not received them.. but I hope they work out alright. They are paying shipping to me with the new ones.
