On Dan's 5 amp drivers, I flipped, and mounted the outputs under the board,
retaining the correct leg positions, and mounted the heat sinks solid to the
chassis. Then I checked each driver to be sure they were not shorted to the
heat sinks. After that I tightened there mounting screws. Next I soldered
the legs of the outputs from the top of the board, worked out excellent.
Lots of air flow around the heat sinks, and the board at the top with the
components mounted on the top where they can be observed, checked.
