I think the supply voltage for both coils should be a common point and either seperate inductors or the same inductor.   They shouldn't be on a core together...


I've been playing with this oscillator a bit, and added a center-tap transformer backwards; but the simulator doesn't really like that... the coils as done in prior sims are not on a shared core, and coulnd't find if falstad has a way to bind arbitrary inductors...


There is a harmonic between the input inductor and the frequency of the coil; if too big of an inductor is used.


The low ohm pullup resistors need to be high enough that the action from the coils is allowed; otherwise the fets don't go off; and they have to be low enough for an initial trigger to the gates; sort of a voltage divider; but both resistors could be increased after starting....


bleh; without proper inductor interaction hard to say what the real result is... but ya, now I understand where the zero in 'zero swtiching voltage' comes from

Hey J
Thats a wild coil you designed been watching your vids, what if you wound a primary around the core , Iv designed a couple of coils like yours, torus shaped.

I haven't had much luck with mismatched inductances but yes, a few turn to a lot of turns should also work.  I recently figured out how to properly drive a solenoid coil and be loosely coupled so this will work well for a tesla driver.... putting one of the concentrated focus points at near the end of a solenoid...


now I just need to wire my royer   now that I understand how to control its frequency a little

bugged up 
I used irfp 460

I cant let go of the ring magnet setup guess I will have to build it. Just to give an idea
