Thanks mk for replying. I can't even find a schematic for the poweramp section. Preamp is the same. Did you ground the resistor to the back of the pot? I only see two wires in the little board you made. Thanks again!

Hi, thanks for detailing this so well! I want to add a bias to mine X60B, but there is so much contradictory information out there and in my limited knowledge, the way you did it makes the most sense to me. But I was wondering, did the values you use work? And if you don't mind, could you please explain or show a photo of the back of the little bias board you made? I'm just not sure what lugs on the pot go where and did you ground the 47k resistor to the back of the pot? Thank you!!!
