Nick,

i was trying to focus on your Oleg snubber, but i have a hard time finding out how it is connected.
According to the below picture, is it right what i think i see, meaning the white wire is the 24V supply wire.
I cannot see where the other side of that resistor goes to, but it seems NOT to go the junction R, C and D's
Please double check the correct connections.

   Ok, well thanks a lot for the comments guys. And thanks to Dog-One for such a nice gift. It certainly will be put to good use.

   Itsu: The Oleg snubber is connected from the resistor to the one end of the black cap, (it's connected underneath the resistor), and the other end of the black cap is going to the two diodes. And from there each of the two diodes is going to the fet's drains. I'll show a close up in my next video. But, it doesn't really do much as it is right now.
  I should be getting the 47 ohm 2w Oleg snubber resistors, and the 1k ohm, 2 watt resistors for the fet snubbers on Friday.
   
   The frequency is reading 15KHz, on the new scope. However,  the 230 plus volts spikes and peaks are much lower than what my old scope was reading. As the digital Siglent scope does not really see nor read the faint higher peaks that my older CRT scope can read.

   I'll need some time to learn just how to use this new scope, as it has more tricks and whistles than I can shake a stick at.
The AUTO button is a great feature on it, as well as the big 18 div, 7 inch color screen.

I consider that 1.5KW (peak pulse)TVS a good choice. However, if Nick firmly establishes that the 'effect' depends on a very hot, over voltaged mosfet, then although a suitably rated TVS will protect the mosfet, the 'effect' may be lost.

   Hoppy:  I'm not establishing anything at this time. Nor am I saying the mosfets need to be going into any particular condition.
I'm simply stating what I see. But, it may be that while clamping the voltage peaks to run under the 200 volts of the mosfet limits,  that that may cause the "effect" to not be present, and not kick in.
   On the other hard, Ruslan and other guys start their device using only a 12v battery. So, even using that lower 12v input voltage can kick the device into that special resonant condition. 
   I'll show what my gate signals look like while the effect is happening, in one of my next videos. The gate, and drain signals do get affected by the HV pulses onto the induction circuits. Which also affects the way the fets work when in that special resonant sweet spot.
And so it looks like specially tuned snubbers are essential, to be able to obtain the effect, while yet not burn out the fets with  extreme BEMF peaks and spikes.

Nick,

when you say:

Itsu: The Oleg snubber is connected from the resistor to the one end of the black cap, (it's connected underneath the resistor),
and the other end of the black cap is going to the two diodes. And from there each of the two diodes is going to the fet's drains.

i understand its connected like this: 

                                                            ----------------------Drain / Primary
                                                           |
                                                       -------
                                                         \   /
                                                        _\_/__
                      ------------            ||       |
24V o----------| 460 Ohm |--- ----||------|
                      ------------            ||       |
                                             1.2uF    _|__
                                                          / \
                                                         /   \
                                                        -------
                                                            |
                                                             ----------------------Drain / Primary

That is not how its shown in the diagram and what i mentioned above in the picture:
"This resistor end should go to the junction of the resistor, capacitor and both diodes (cathode)"


The capacitor should be grounded at one side like this:


                                               ----------------------Drain / Primary
                                              |
                                          -------
                                            \   /
                                           _\_/__
                      -----------          |        ||
24V o----------| 460 Ohm |------|------||-------------|
                      -----------          |        ||                 |
                                           __|__     1.2uF        ------
                                             / \                         ----   
                                            /   \                          --
                                           -------                   
                                              |
                                              ----------------------Drain / Primary

I should be getting the 47 ohm 2w Oleg snubber resistors, and the 1k ohm, 2 watt resistors for the fet snubbers on Friday.

You got that reversed, 1K is for the Oleg snubber etc.



By the way, spectrum analysis of your Radio Moscow noise shows some peaks in the 6, 7.5 and 13.8 Khz ranges.

If eventually you get the 'effect' without the mosfet getting very hot, then you will have automatically established that its not primarily due to an avalanche condition. I was not suggesting that you to do anything particular to establish this, or decide on a condition that's causing it.
