One interesting thing. The MOSFETs are rated at around 70A, but the
leads look smaller than a 7805 regulator. I wonder if thay could
actually carry that amount of current.

I have to admitt, I've always wondered about this.  Here in front of me is a Farnell catalogue with a TO220 device rated for 110 Amps continuous, 420Amps pulsed!!!  I just can't see the legs on this device taking that current for more than a few ms, let alone the internal bond wires.  On a slightly unrelated note, does anyone know of a MOSFET *full* H-Bridge in an SO package or smaller.  Max current is about 2 amps.  Half bridges seem to be ten a penny, but full bridges seem to be virtually unobtainable in anything smaller than DIP.
