For some reason I'm not understanding the prints for this input board. Q9 and Q10 require the same devices but the schematic is showing different devices, both with heat sinks. 2N5551/2n5401 cannot be heatsinked. Input schematic doesn't show both channels only one side. Unless these prints aren't correct?? Any answers?
Looks like there are a couple of differences in the various versions of the schematics.
On the schematic I posted (which I think is V2 boards), Its Q9 (MJE182) and Q12 (MJE172) that require a heatsink, both are for the power supply. Also Q7 (MJE 182) and Q8 (MJE 172) on the output can get warm and would probably benefit from a heatsink, although I haven't had any problems without a heatsink.
The input board itself is simply mirrored and the labelling is pretty good.
