Default Jeff Rowland Model 7 mk2 bias adjustement

Hello all,
I've got the Jeff Rowland Model 7 Power amp and because of one of them are a bit warmer than the other, I would like to control the bias ... Does anyone have informations about the method to do that ?
For information there is a screw on each of them where "bias adj" is writing but I don't know the factory Voltage "measures"/"data" and where/how I have to take it.
Please excuse my bad english ... I'm french

Many thanks for your help.

N.B : My model 7 are the "B" version, I suppose that mean MK2 version ... (with XLR inputs)
