Default How do I get the bias higher in this amp ?

I am modifying this amp and will post the results in a separate thread, but one specific question here: Currently the amp stays very cool (I guess class b). As it has big heatsinks, I would like to put more current through the end-transistors, but as I am coming more from a tube-world than from an SS one I have no clue how to do it. So, what do I need to change:

THanks a lot

the bias is controlled by the resistor network around v206 (5551). you can replace r256(258?) or r257 with a pot.
