Are you confusing bias with DC offset? Be careful if you aren't 100% sure of what you are adjusting. You WILL blow up the output transistors along with other stuff.I have set trimpots as close as possible to 21.12 as manual stated.

Measure the DC offset at the speaker terminals with everything disconnected and volume at maximum (select a line input if using an integrated amp).Do you need a preamp connected to the amplifier to get a "true" reading, or can this be done with the preamp disconnected?
Volume at minimum, not maximum .Measure the DC offset at the speaker terminals with everything disconnected and volume at maximum (select a line input if using an integrated amp).
I also notice a strange thing. My readings are actually negative. I am sure the connections are correct. Any explanation?
