Llano CAS 300

I have two of these beasts, I use them to drive a pair of Soundlab A1s in a vertical biamp configuration. One of them self destructed, and got fixed by a local shop, but they biased in a very low AB, the other still runs at about 50F above ambient while this one is dead cold to the touch...the question is, does any of you know how to adjust the bias in this thing, There are two multi turn pots on a small circuit board....why two? Anyway any help would be greatly appreciated...since i have the other i can measure things to make sure they are the same but without a circuit diagram, i have no clue what is what.

Thank you in advance
