Hello Brett,

Okay!  at least some people want them!  The board looks really good,  only
3.5 X 4.5 and has everything but the low voltage transformer, and the high
voltage power to the flyback primary.

I sent the quote in today hopefully they'll get back to me later today.  The
PCB will be aluminum based (I hope) so it will be able to carry the large
currents etc that the bridge will be switching.


Regards - Jim Mitchell
