Default MA Audio HK-401sx current draw issue

Iv fixed the smps section, rail voltage is fine, output stage is fine, caps are fine, but I get 2ma of current draw with only the B+ and Ground connected.

Iv pulled all the diodes and tested them, rectifiers out, power supply fets removed, still has the same 2ma current draw.
All my battles have been won, But the war has just begun.

Do the op-amps or comparators in the power supply have any DC voltage on any pins?
