Re: [TCML] Brandon's new coil

[Brandon Hendershot <brandonhendershot@xxxxxxxxx>]

Hi Charles,
Interesting proposal. Can you give me a briefer on the pros and cons you've
observed between DC and classic AC coil circuits? I don't think I want to
invest too much into a single coil at this point, since I'm still not
showing any signs of showing regarding going bigger. I'll be doing some
research on them tonight as well when I get some time.

Thanks,
Brandon H.
