Bert, David, John, Daniel,
Thanks very much for your responses and thanks for the links. I have read a lot of Richard Hull’s work, he wrote a fair bit about maggies in the Colorado Springs Guide, a book I really enjoyed. Unfortunately it seems not many modern coilers share his enthusiasm for the magnifier. Whether or not this is justified is something I am hoping to figure out. I’ve also been reading some of Antonio’s work and need to just slow down a bit to digest it all (not the smartest person here).
In the meantime I have been doing some simulation to understand tuning points and obtained results I would love to have explained. It’s detailed here:

Any thoughts would be fantastic – feel free to comment on the page if you don’t want to clog everyone’s inbox.
Regards,
Greg

Subject: Re: [TCML] Back again....and Tesla Magnifier Tuning
Hi Greg,
The technical development of a theory for Tesla Magnifiers, as well as
tuning options has actually been solved by one of the members on the
TCML, Antonio Carlos M. de Queiroz. Antonio presents the theory and
practical methodology for magnifier design as well as many helpful
design tools.
See Antonio's web site for more information:

Best wishes,
Bert

Is the primary normally tuned to match the resonant frequency of the extra coil alone (plus some for streamer/corona loading), or is it tuned to match the aggregate resonant frequency of the combined secondary and extra coil? Or somewhere else completely?!
