Re: This phase shift stuff...

Hi Jim,

	One could build a TC in a can which would increase the capacitance along
the seconday greatly and push the system into more of a transmission line
type of system.  However, would this be a realistic system to compared to
the regualar kinds of Tesla coils we all use?  I am really looking for the
effects in the standard type of system with no tricks.
