does anyone have a CM Labs 911 Schematic

Thank you very much that solves the wave form balance problems
also I have a good schematic now but it does not show the wattage of the pots 
or  where to get and how much bias voltage should be.
I may have to buy the schematic and hope it is in there.
I never could get a answer from Mr Wayne Chou I hope he is OK.
and he is just a busy guy.
thanks again.

The 8mv from the output is due to the leakage current of the output capacitor, I think your amp is over 40 years old so best to replace those caps.
The 911 is a single rail power supply, output capacitor coupled power amplifier, I don't think you can adjust "DC offset" on this amp. I believe the "balance adjust" pot is to adjust the voltage before the output capacitor (at the + side of the cap) for max output without clipping, in most case is half the value of the power supply rail voltage.
It's best to obtain a service menu for bias and balance adjustment.
Good luck

ok I get 8mv with a 8 ohm load but balance adjust doesn't do much stays at 8mv also 3v across ? ohms on wire pots = ? wattsalso what points do I measure bias adjust from and what are they set at ?

unit works OK but for the 2v dc on both sides of the speaker outputs that I cant adj out

Did you connect a load to the amp output to do the measurement?
The 911 has a output capacitor, if no load connected, it will show some DC reading!

also the balance and bias controls are wire wound pots I am wondering if I can get away with 1 watt or smaller on these controls?

You can measure the voltage across the pot to calculate the wattage required.
Hope it help, regards
 

cool I could not find anything- thanks much but it is to hard to see the values of the resistors and caps in this photo plus I need the part numbers also again thanks for the try. color me still looking.---
