NuTone NM200 power supply and amplifier board

The 3 red arrows point to 3 output transistors (one is hidden on the back of the heat sink) and the blue arrows points to a voltage regulator.

The power supply / amplifier board is designed with through-hole components, which means it will be easier to repair this board if a problem occurs.
