Default Kenwood KAC-9104D output drivers?

I have a 9104D here with blown low side output transistors so I figure I'll replace both high and low sides.

What are the 2 driver transistors for the high and low side output transistors? Q112 and Q107? I can't get anything to show even using heatsink compound. Also R197 should be 47Kohm SMD(source resistor), just like R188 correct?

It also seems to have lifted and broken the trace that connects the ground of the transformer to the jumper for the ground terminal. Should I just install a jumper wire connecting the transformer directly to the jumper?

If anyone has a schematic for this amp they would like to share with me it would be greatly appreciated.

thx as always!
