Finn,

Yes, still no schottky diodes. Now that I have a current probe I will be
taking some definitive measurements as soon as possible. As the moment,
however, I am in the process of moving so it might be awhile.

Aron,

Cool.

Are you still runing at this power level without the schottky diodes inline
of the FET`s?

Cheers, Finn Hammer
