Re: [TCML] DdRSSTC driver board with parts

I have not seen a coil use CM1200 ether. It would be interesting to say the
least. You would need a heavy duty gate drive and possibly phase lead.
Daniel I know your work well, very fantastic work especially in your
mechanical design. Your coils make me wish I had a machine shop.

The best I have as fare as power tools is a drill press and a band saw, but
I make due
