My Consonance Cyber 211 failed I need directions diagrams of the components etc. Help!

My wife let the wire to the speaker come off and the amp failed.  My repair guy is inexperienced and does not have any diagrams of the amp,  Consonance has helped a little and sent me a replacement transformer.  However when we attempt to set the Bias a 4.8 it will not get that high leaving at 0.8 instead.

This is the silver amp that I bought off of the review for the Stereophile  Review.   Can anyone help with suggestions or a diagram of this fine amp?
