Akula0083 30 Watt Self Running Generator.

[Vortex1]

My dual 494 circuit is built up and the transformer wound and connected. I am taking a slightly different approach and not trying to light any LED's, rather I am allowing 100% of the output of the 19 turn winding to bootstrap the power input using a Schottky diode.

My reasoning is that it will be easier to find the sweet spot without trying to drag the load of the LEDs along with the other circuit quiescent burdens.

I am supplying 9 volts input from a power supply (through a decoupling diode) and am watching the current as I tune, the idea being to find a sudden dip in the current drain, which is typically around 10 mA. So the circuit completely bootstrapped draws around 90 mW at one setting of the pots.

If the sweet spot is found the voltage should soar beyond the 9 volt input setting and the voltage shutdown potentiometer is set to shut the circuit down at 10 volts. If the sweet spot is found, the oscillator circuit will then be "gated" as it cycles around the voltage limit.

I am also watching the waveforms as I tune.

With such a broad range of tuning, and so many parameters to tune it is like trying to find a needle in the haystack. It would be helpful to know the approximate center frequency and duty cycle for each oscillator in an attempt to narrow the tuning range, but I know this will differ for each ferrite used.

Note that the transformer phasing dots on the hand drawn schematic are not shown on the later "cleaned up" schematics.

You cannot assume that a member of an English forum will understand the nuances of a technical text written in Russian.
I have not been shown anything meaningful to me and you still have not answered my question directly.

Actually Google translate did a pretty good job with this document: (for a nice change)

When conducted experiments on nuclear magnetic resonance, the resonance
frequency ferrite sought so (more options I have not found).
Pickup coil must be arranged in other geometrical axes.
Moreover, the number of revolutions does not affect resonance.

When a short pulse (0.5-1us) 12-20 volts...

immediately see the frequency of the ringing...

Appearance generator short pulses...

Akula say somthing like that, that this two generators must be sinchronised. If I good remember передние фронты должны совпасть. First fronts of one generator and other must opens at same time, close can not at same time. From video wthout supply we hear that one frenquency is can be quate low, about 10-17 kiloherc (because we hear them). Other frenquecy of HF generator must be somethig like 200-300 kiloherc with lenght of signal/pulse 100-300 nanoseconds. Because feroresonance frenquency, for example, in one Akula ferite is 3.5 megaherc, so you smash every five or every 6, 4 pulse. Akula in conference, who be yesterday say,  how he finding feroresonance frenquency. He puting near ferite coil and puting to it signal from generator of noise and on ferite is one turn of winding and that turn he conect to spectr analiser, and then see everything, all frenquences...

About Akula0083 30 Watt lantern Akula say something like that, that this schematic is not compleated, but he not give full schematic. And all this schematics he made (Lantern 80 W, Lantern 60 W and so on). For example in Lantern 80 W shine incandesel lamp, how he say.
Ruslan, who replicated this 30 W lantern, and we see his videos, also say, how I remeber, that Akula give not fully compleated schematic, something like this he say. And akula say something like that, that this schematic not easy ajust, he ajustingwith oscilioscope after it stop working tomorow for example, something like this he say, but and not too hard ajust.

Hi MenofFather,
I'm assembling this circuit testing, because considering Video clip shows it is not fake. But the value of the components on the circuit diagram can not certainly true. Regarding the operating frequency of the circuit can approximate as you say. . .Play Video clip, I listened, Mr Akula have similar noise axis potentiometer adjustment of the oscillation frequency of the horizontal Television. . .

You may provide additional information about this circuit?. . Or more details on Mr Akula said. . .
