Default Rockwood bias prob

Hi all

This amp came in with blown PS FET and two coupling capacitor that's right behind the
Speaker terminals.I replace them, amp powers up and plays good audio on both ch.
The bias voltage has a problem it keeps going up until I shut it down at about 3.01mv
It start at 0.01 just after I power the amp.I install two outputs just to make sure the problem is
not cause by leaky outputs but no change.Any idea what to check?

Will post model later
