RE: [TCML] SISG coil



Bart,
I'm just curious, but it look like the caps are located on two brackets
which bolt direct to the wood. If so did you not get problems?

Regards

Thanks James,

Yeah, built one myself
http://www.classictesla.com/photos/sisg/sisg.html

My output was ok but not quite wonderful. I suspect due to running a low 
60nF which is why I was curious about your cap size. A couple weeks ago 
I pulled the SISG out of the base as I plan to refit this coil for a 
DRSSTC (due to the turns and frequency, it's usable in a DR, although 
maybe not ideal).

Take care,
Bart
