Was blown all, psu, outputs their drivers.
After installing all new parts, amp is drawing excessive current.
Amp is now without output transistors, drivers (q108,q109).
The voltage on, amp ground terminal as reference. q105 (2sb631) 1)emitter +55,7v 2)collector +55,3v 3)base +55,2v
q106 2sd600 1)emitter -55,2v 2)collector +55,3v 3)base -55,2v.
What i am missing. Cant find any shorted parts.

You cannot troubleshoot inside the feedback loop using voltages with the loop open (missing the output transistors). I'd suggest installing the outputs, clamping everything down to the sink and powering through a current limiter to troubleshoot.
