In Reply to: I have used the 12AU7 with Good results. posted by Cougar on March 15, 2023 at 09:26:45:
Thanks! It sounds like you are doing what airtime recommended a couple of weeks ago as a comment to one of my prior posts, and I was partly following up to make sure I understood.
So a single 6SN7 could do the trick with an adapter and no other necessary modifications to the board, or is the ST120 circuit different from the ST-70? I can certainly ask the builder who's been super helpful
Do you have the VTA driver board in yours? I was worried that there wouldn't be enough space on either side where the 12au7s sit but I assume the board dimensions are about the same?
