Quite frankly, I cant hear a bit of difference between an old 12ay7 I have laying around or any of the 12av7's... then again, the 12ay7 I have is a bit old, and tests to about 92% on my tube tester, which the 12av7 tests at 100%, so the gain is probably closer here. I dont think even new, however, you would hear much difference in a gain factor of 40 vs 44... now an at7 has a gain of 60 or 70 if I recall, and that is quite a bit different, and a 12ax7 at gain of 100, is MUCH different... Then again, comparing 12v7 from mfr. a will sound different than a 12av7 from mfr. b... I'm logically deducing that tere would be really very little if any audible difference between a 12av7 and a 12ay7 from the same mfr.. I would go as far as to bet they are the same tube, just labelled according to the mu of the tube.... Besides, when you are talking less than $2 per 12av7 vs $15, $20, or even more per 12ay7, the differences in sound become even less noticeable. Another thought to ponder... put a 12 ay7 in an amp where the resistors have drifted to the + side of the 10% tolerance, and put the 12ay7 in the same amp after putting in resistors that are closer to spec, I'm thinking the gap between the sound would get tighter. |
