The fundamental question I had when trying to get a grip on Magnifiers, is. Are Maggies triple resonate or double resonate. By looking at Antonio's write up it would seem to be a triple resonate device, but reading Richard Hull's paper it would seem to be double res. system.
All simple tesla coils are doubly resonant (Lpri, Cpri & Lsec, Csec). A magnifier has 3 resonances.
Antonio's analysis is pretty definitive - he identified a whole raft of possible topologies with their associated couplings, etc. (and I just realized I need to take a new look at it, I've got a microwave problem at work with coupled waveguide resonators and a magnetron, which is a resonator as well)
From what I can gather, Tesla him self didn't seem to be concerned with capacitance of his secondary. which would imply to me that his primary and secondary was just a single resonate pulse transformer that fed a highly resonate extra-coil.
That could be.

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:http://gregsstuff.com/2018/08/01/tesla-magnifier-scoping/Any thoughts would be fantastic – feel free to comment on the page if you don’t want to clog everyone’s inbox.Regards, Greg Sent from Mail for Windows 10 From: Bert Hickman Sent: Wednesday, 1 August 2018 6:11 AM To: Tesla Coil Mailing List 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.
