i can only find one transistor (per side) when i follow the traces back. will they be close or could they be at the other side of the board? the 2 i found are 1266's. are the 2 im looking for the same dimension as the 1266's? or are they a different size?
and should i replace the small resistors on base leg of the outputs?

Some amps only have the PNP drivers. If you have a diode connected from base to emitter on the 1266, there won't likely be an NPN driver transistor. This applies to the power supply, not the outputs.
If the base resistors for the output transistors are out of tolerance, you need to replace them.
Some of this sounds like it's for the power supply and other questions appear to be for the audio section. Did both sections have problems?
