Hi Roger,

Nice coils! Can you comment on your TC coil geometries?

I use a home made, 6 Hennery  charging reactor for my DC resonant charging 
Tesla Coil.   It is basically just several thousand turns of 24 gage magnet 
wire on an "I" core and I use many layers of packaging tape between each 
winding layer for insulation.   This is fairly inexpensive way to make a 
choke but it is tedious.

Here is a link to some pictures.
