I changed out those phono tube grommets - what a pain! And I have 3 caps left from metalbone's kit - in the mpx section - C214, C221 and C222. The first one is doable, the last 2 NO WAY! Them suckers are buried! Then I swapped V15 and V16 and rebiased it (Larry I'm pretty sure the circuit is good - I measured the range at all 4 tube sockets before I even put the power tubes in). V14 .307 V15 .307 V16 .256 V17 .253 If I try to bring 16/17 up any higher then 14/15 go up too. B+ is 410 across the board. I think I need new tubes. Plus I swear the left side sounds better (hotter bias), but maybe it's the janky volume pot messing with me. Mark wants $125 for a new one, I might bite on it.
