, so I am changing out tubes and i have JJ KT77 in there. My bias pot will not get me in where I need to be. it jumps from 28 to 60 Mv with no way to get in at like 40 or so.
Whats up? is it broken or is there a trick. never had this problem before....6L6's dial in fine.
closest I can get the KT77's is 34/32 Mv, then it jumps to 60's at the slightest touch.
