Pig nose 30/60 biasing
« on: February 22, 2021, 06:36:23 PM »
Hello all,
Working on a Pignose 30/60, which doesn’t have any bias or offset pots, and I just replaced the drivers and output transistors. The amp sounds great, but my background is predominately vacuum tubes so I’m not even sure whether this even matters?

If I can figure out how, I’ll post a schematic. The amp is from 1979 but the schematic is on the web.

Thanks in advance,

Pete

I just started a new post about this same amp and included a schematic in my post if that is of any help.

Iit works and sounds great?  And there ar no adjustments anyway?  Then stop fixing it and enjoy the amp.
