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

["Dr.Hankenstein" <dr.hankenstein@xxxxxxxxxxxxx>]

Look's if you stuck an 811A into the tube socket and flipped the switch;
It might work! Look: http://www.audiotesla.org/811A%20Coil.htm This one
was built in the late '70's with two 811A's....similar in style. You've
got a real oldie!

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.
