Hey guys, took the amp to Peter. There was nothin wrong with it. As you have said higher volumes are the key. But I also got to hear the mighty Herbert first time through a Diezel cabinet and it is really a beast. Anyway, Peter also did some tweaking and I ended up replacing the EL34s with KT77s. I am very happy with my Herbert, it's soo amazing !!!

Glad to hear you solved your problem. Always good to speak to Papa about the intricacies of the amps. And what shadow said is right, Diezel cabs are awesome!! Run my Herbert through a full stack, K100's in the top 4X12 and V30's in the bottom one
