Kapanadze Cousin - DALLY FREE ENERGY

[PolaczekCebulaczek]

I'm afraid I can't answer that, because this is the first time I've seen that connection used. I can tell you that in normal Tesla coils, you definitely do NOT want the mains power supply connected to the secondary as this can be very dangerous to people and equipment.

This is exactly what I want, It doesn't have to be mains AC 60 hz, we can use other AC HV HF current source, I have a strong feeling that this is HOW the the russians hoaxers do their FE videos ... maybe old man Kapanadze as well..., current from another hidden power source is flowing in earth or water pipe and "free energy" device resonate with it.

Eerr could you please explain your theory behind your theory   on how that could possibly work and how Morrey could have faked it in the 40's please.

Not yet, first I have to run some tests..  Mooray device was genuine free energy device, one on the few that really worked and this cant be said about primitive russian devices that we are seeing lately.

I'd need a 2-ch scopeshot of the drain current vs. drain voltage to be able to see what is stressing your MOSFET (look at Itsu's videos how to take them).
Good question.  The "Stalker" schematic seems to show a +15V regulator on the TC4420's supply rail.

Note, that the 12V Zener diode string at the MOSFET's gate will break down at 12.6V which is 2.4V lower than that +15V supply rail, suggesting that these Zeners are conducting in every cycle (only the 10Ω resistor is limiting their current).
A Zener current scopeshot would reveal that.  Gate voltage would be interesting, too.
5. The MUR1560 is a good fast high-current diode, I use them a lot myself. I'm not clear, however, how this works when used in addition to the snubber network. Maybe someone with more experience can help out here.

Such diode placed in antiparallel with the MOSFET (D-S) would only augment its internal body diode.  This makes sense if the external diode is faster and has a lower forward voltage drop (V_F) than the body diode.  Does it?

   Verpies:  I made the changes to the snubbers, so that the 1k resistor and the two facing zener diodes are connected to the mosfets gate side of the 10 ohm resistor. But, no noticeable difference, the fets are still untouchable in less than one minute run time. And this is with a small fan on them, as well.
   The fets still overheat even if using a 12v, 7Ah battery, as the input source, and once going through the voltage regulators, and filters, there is only 11.8v at the TL494, as well as to the drivers.   So, I'm still looking into what is hogging up all the current. At times, depending on the duty cycle control, and the frequency, the draw can be over 10A, and the power supply will kick off by it's over-current protection circuit.
   I'm using 18v zeners on the snubbers at this time, as in the Ruslan diagram.
   My power input is from a 24v, 10A power supply. And the load bulb(s), one or two 100w bulbs, are still lighting at low levels. Even with of best tuning of the TL494 trim pots.
   Somehow, it looks like both the Kacher and the push pull are running at the SAME frequency.
   I need more time to get to know how this is all working, or not working. As something, or several things are not working right, as yet.  However in further looking into it, it looks like both FETs are on at the same time, at times.

And what frequency is that ?
Do you remember a couple of vids by a guy called G Sav see if you can find them and go through them the one coil was 4 time the frequency of the other but it was not a self runner.
