Bob, I was looking at your H-bridge and you mention that
separate free-wheeling diodes are not required since the TIP
transistors have diodes internally. Are these really robust enough
to handle the inductive surges?

BTW, it looks like your ckt could almost handle the currents
Duane Brantley is requiring. Can you possibly parallel the
TIP's to get more drive? Tried power MOSFETs?

thanks,
