Can anyone look up the generic part numbers for Q112 and Q113 for me?
Thanks

Is there a schematic?
When I was servicing for QSC, none of the parts had coded numbers or house numbers. There were unusual parts like IRFZ44, but that is a real part number.
What numbers are on the existing parts? If they are burnt, look at the other channel.
Or where are they in the circuit, what do they do?

This is a very small transistor and I dont have a microscope on my home bench. I will have to wait till I have access to my microscope I guess.

Add a 2N to the schematic part number.
Q112: 2N3904 small signal NPN
Q113: 2N3906 small signal PNP

Due to the fact that these transistors are "very small" (I suppose the packages are SOT23 ), corresponding part numbers are MMBT3904 (or FMMT3904) and MMBT3906 (or FMMT3906).
