does anyone have a Schematic for a CM Labs 911 amplifier


Hi does anyone have a Schematic  for a CM Labs 911 

 
 any help will be Great!--
 also known as  CM Laboratory  911
I have a 2v dc off set problem I think it should be 0v.
I checked all caps and resistors all ok I just replaced the main B+ caps
unit works OK but for the 2v dc on both sides of the speaker outputs that I cant adj out, 
also the balance and bias controls are wire wound pots wattage unknown I am wondering if I can
get away with 1 watt or smaller on these controls?
