Can someone circle the resistors for me? I would think they would be fairly
decent wattage so they would be very easy to see, but I don't see any
resistors.
I 'think' (but I'm not sure) that these are the resistors in series:

If they are resistors, I've never seen any that look like that.
Also, given that you want to thermally bond any components
that generate major heat, why are they not heat sinked?
With any power design I've seen, the key components, eg
the transistors are directly bonded to the heat sink.
THey make power resistors in T0-220 style cases, for heat sink mounting
however, I doubt those are that.
