D'oh! I meant medical grade Amperex 12AX7. I mentally misfired because I had VAC install a 6922 switch for the 8416 tubes (at their recommendation) in the linestage and was thinking the tubes I'll use to roll that position. No, I'd never put a 7308 into the 12AX7 socket. :) Thanks for catching it.
VAC Signature MK2a pre "phono tube questions"
Hi there I have a VAC pre with MC/MM, upon opening noticed there are two roles of 3 12AX7 tubes in each totaling 6.
Question;
1. Anyone have any experience tube rolling these and if so with what?
2. Are they three matched pairs or all matched?
3. They are a Chinese tube that came standard with the pre., anything special about them?
I have found on other gear which came with Chinese 12AX7 tubes they were nothing special and by substituting I found the sound was transformed, sounding allot better using other tubes.
4. Can you mix and match, say the first role Bugle Boys, second Tel for examaple or best to stay with one brand through out.
I have allot of really nice matched pairs but only that.
Any assistance would be appreciated.
