Re: [TCML] The Practical construction of VTTCs

[Neon Tesla <neontesla@xxxxxxxxx>]

           Yes I think paralleling MOTs is best now that you
mention it, since I can't find hide nor hair of the shunts on
my MOTs. I also want to try out an oil filled secondary to
see how well it works before implementing it on a 12"
coil.

           Thanks
