Yeah, 12AX7 settings confirmed. I had to double check b/c it whacked the meter. Mind you, my slew of other tubes have never pegged. 10M's, RCA gray and blacks, GE's, Brimars, Japanese tubes, etc have never tested this high. Even JJ's, while high-ish never hit the wall. So, in the end, I'm asking will using them just to "fill the hole" in the phono stage adveresly affect other circuits or damage the unit. What I'm reading is that the tube could eventually let go thereby causing "damage" but that would be much like any of the other tubes going. And if that is going to happen 500+ hours down the line, I could live with that. On the other hand, if it'll go within the first 100 hours b/c of the gross mismatch, then I'd toss it and plug in something else.
