Hi.
For those who want to know something more about resonance. Are you aware of works of those guys: Minorsky, Mandelstam and Papalexi? I'm in possession of their works in pdf. Here are two of them. Only, they call it "Parametric Excitation" instead. See these links:

https://drive.google.com/file/d/0B-m4PqHpBHo-Ylk3QmhFNy1hbVU/edit?usp=sharing  1935

I've decided to add three more works: two patents based on the above info and the original work (over 700 pages).

Hello Everyone,

I have been following this thread since it began and have a question. With all due respect, how many of you guys have actually built the circuit and tested it. Not with a simulator, but actually built it?? It would be more interesting and productive to see people talking about their builds and test results instead of arguing over simulations and theories about a circuit that seemingly hardly anyone on here has actually built.  For what it is worth, I have replicated the circuit faithfully to the letter both the original version and modded versions. None of them work as advertised. In fact, feeding ANY positive voltage from C3 through L2 to C11 causes the circuit to bog down and current draw to shoot through the roof. Looking forward to hearing results achieved by others.

Four, and more are posting their builds at O.U.R.  One member even had a PCB done for it, (see here)
The circuits work as in simulations, but then the circuit is not the mystery here...the transformer/inductor is.

For what it is worth, I have replicated the circuit faithfully to the letter both the original version and modded versions.

What modifications have you tried?
How did you wind the transformer (L1 & L2) and what core did you use?

I can't resist to disclose this extremely unconventional book of C. P. Steinmetz of 1900, "Theory and Calculations of Alternating Current Phenomena", pdf download available:

Thank you for the files Qwert, can never have too many files to read. I copy reference material like this to my laptop as well.  Much appreciated.

Cheers
