I do not get much emails from this group, but you can suggest to me a
specific list.
I'm a little new to Tesla Coil making, but I've made some kits that had
instructions and the parts, so it was easy.
But I like to learn to think for myself - so I'm looking for a place/group
that is teaching the basics so I can at one point make my own.
Thank you very much for your hard work!!!
I wish you Happy Holidays, Happy New Year and maily I wish you lots of
health!
Tony Fleming
