Cool, thanks Terry (I'm really not going crazy!).
I modeled the Wendover coil and came up with a completely different set of parameters (thus, my concern). I can say the Wendover coil primary and secondary info was excellent. Both were about 43 kHz. The tertiary interestingly was closer to 100 kHz. Something is wrong with the 3rd coil setup (either very wrong or something is seriously missing. i.e., force driven? because it is "absolutely not" resonate to the primary and secondary - even with huge toploads.).
Bart,
Normally in a magnifier design, the tertiary coil is not actually resonant with anything else. It's the combination of the tertiary coil and the secondary coil which taken together are resonant with the primary. The secondary and tertiary coil behave as a single coil in some ways. Antonio has worked up equations for building a design which can trap all the energy in the tertiary at one time (provided the quenching is adequate), but Tesla did not design his coil that way. Also regarding the coupling, the overall coupling of a magnifier system is lower than the the driver coupling. Antonio also has an equation for this.
