My question: I'm interested in the auto bias board, and would be especially interested if there were version with the auto bias LEDs on the driver board or visible from above. I see that someone on ebay has a version of this for the ST-70. (Seller name zpra-72) My question is whether something like this exists for the St-120. I know the possibility was discussed on this forum but couldn't tell whether anything came of it.
I've built kits and can follow directions, but don't want to improvise too much, so I'd be interested in something designed for this purpose. Is there such a thing?
(I'd be especially interested in an ST-120 octal board + auto bias board with auto bias LEDs on top. I have a box of 6SN7s, so I'd be in a position to play around. But that's a project for another time. I'll build the 12AU7 version first.)
