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.

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