[QUOTE="Bucksears, post: 77952, member: 2627"] Well that's the interesting thing. After reading your reply, I just powered it up and tested 1) that they were in the correct operating voltage range and 2) did the red-lead on test point 1 and black-lead on test point 2 to measure how closely they were matched. The quiet pair was actually much further apart (5.8mv) than the louder pair (1.2mv). It's cooling down right now - I'm going to swap in the EL34Ls for the lesser-matched/quieter TAD 6L6s and leave the closer-matched/louder JJ 6L6s in there, take some readings on the EL34Ls and then take it to a tech.
