Re: [TCML] Old VDG and Tesla coil found in attic

[David Speck <Dave@xxxxxxxxxxxxxxxx>]

Nope, Dan,

"Big TC" was a disruptive spark gap coil, while Steve's is a VTTC.

There was a "Lil' TC" plan published in the same popular Electronics 
issue as "Bit TC", but it used a TV flyback transformer as an output.

Steve's TC is from a schematic 30-40 years older than the Big TC article.
