o.k. fellas. have a good laugh.I deserve it. just reminded myself of a long forgotten lesson.never,ever under any circumstance, allow the customer to figure into the diagnosis of a tube amp because if I never learned anything I learned that brand new matched set of tubes couldn't possibly be the problem.they're brand new.guess what customer...your brand new tubes suck. dug a pair of 12ax7's out of the trash to sub for V1 & V2...quiet as a mouse.no hum,no buzz just quiet.
