Beomaster 4000 – extra components not documented

[Mogens Ranneries]

Hi Forum. I am recapping another Beomaster 4000, but this version has 2 extra trimmers in the output stage, and I cannot find any documentation stating how to adjust them. It seems that they may effect the center/symmetri voltage of the output stage. See attached picture, which I scanned from the in-lay schematics. Unfortunately is does not say anything about adjustments. The extra trimmers are position 585 and 586 (right channel).

Anyone who has seen this version and knows the adjustment procedure?
