[TCML] Tank Circuit Design

[bartb]

Hi Thomas,

Are you looking for this?
http://www.classictesla.com/hot-streamer/TeslaCoils/MyPapers/NSTWindingStress/NSTWindingStress.html

Best to check with Terry before linking anything just to say on the up 
and up. BTW, yes, the phrase with "inductance, not shown" is only an 
opinion. RC Filter is the most widely used.

Regards,
Bart
