Void:
   It's not just a "little effect". It's the real deal... without it there is very poor output.
   I did install a CT like you mentioned, today. And did adjust for the highest output at the CT, as shown on my scope.
   But, what really seems to set it off, after tuning with the CT,  was moving the yoke around a bit. That kicked it into what Itsu would call the "Chaotic mode". It's there that the magic lies, and the effect is to be seen. Similar to what the Mazilli would do.

    Itsu: It seems that the static ringing noise like Geo had shown, is part of the "special resonant effect". At least on some devices, like mine and Geos.
 And without that sound, I don't see the same kind of "effect". That sound can also be tuned best when it reaches a steady clear ringing sound. I'll show all these things in my next video. If my FET's live that long without the proper snubbers on. Which is why I'm lowering a load of bulbs on until I reinstall the right type and value of carbon resistors back onto the snubbers. As the higher load, like 600w, induces higher peaks, up to 230v in my case.

Itsu I was going over some of your information you shared on this post I recall you saying you failed to achieve to gain Akulas goal, If I remember correctly somewhere in that or a similar video he mentions a threshold where he says the focus lies, I'm pretty sure the frequencies you quote are far too high and you may do better to look lower.

Hi Itsu. If you still have your PWM connected to the ferrite yoke (or equivalent toroid)
with the series resonant loop going to the grenade, and, if you have
some time at some point, I wonder if you could check something for me?

Would you be able to wind a few turns on a ferrite toroid to make a
homemade current transformer and place it over the wire on the series
resonant loop (like Ruslan did previously), and connect one scope probe
to the homemade current transformer output and a second scope probe to show
the output voltage across the two output wires on the grenade coil with
the PWM running? A commercial current probe may include phase shift correction,
so I wanted to see if possible how it works for you when using a simple homemade
current transformer as Ruslan did previously, for comparison.

I just wanted to compare the phase difference that you are seeing between
these two waveforms to what I saw in my own tests. In my own tests using a
homemade current transformer like that, I did not see the 90 degree phase
difference between the two waveforms (loop current and grenade output voltage)
which Ruslan showed in one of his old videos. Just wondering what you get
when you use a homemade current transformer on the current loop? I see
either 0 degrees or 180 degrees phase difference (depending which way the scope probe
wires are connected), not the 90 degree phase difference that Ruslan showed (with
the Kacher turned off). 


Nick: That funny noise you mention may just be a spot where the
PWM goes unstable (parasitic oscillations or similar). That might well explain why
the FET gets hot. You would likely be able to see what is happening by looking at the
Drain to Source waveform of each of your PWM driver FETs with your scope
when it is happening. Would be informative to see what the scope shows
on the PWM driver FET waveforms when that is happening. It is interesting that you
see a little effect from the tesla coil when the PWM is doing that however.
