For 4 ohms I'd lift that one 220uf cap to loose the swinging bias. (I forget the right term)

hello. i was wondering. how do's the rail voltage influence the DC ofsett?
i got 25mV at the moment. with +/-50V rail. but only get 2.7A bias with R19=56.2Kohm. i'd like to get the bias up to 3A and the DC ofsett even more down to 0. the bias part is easy. but how will that effect the DC ofsett?
