As I have read elsewhere, in other threads, using a 12AU7 in V3 has been cited to improve bass. So last night I tried the experiement with two different 12AU7s (an EH and a JJ) in V3 (the position closest to the front of the preamp).
This did NOT improve the sound at all.
I found it to be etched and bright, and not at all improved in the bass. Replacing the Gold Lion 12AX7 brought back everything into balance and focus.
