Swap out 12bz7 in favor of 12ax7?
I've asked this question before, but maybe wasn't specific enough so I thought I'd try again. I have a Cary V12r amp which has two 12bz7 tubes in the signal path. I understand that the 12bz7's are a high-gain alternate to the 12ax7. The question is, in this amplifier, could I take out the 12bz7 tubes and replace them with the lower gain 12ax7 tubes? I know a fair number of A-Goners have switched from the 12ax7 to the 12BZ7 for the added gain but I'm looking for the the opposite. Any thoughts?
