Akula0083 30 Watt Self Running Generator.

   I would (again) suggest looking into the tuning methods provided by Dr. Stiffler, as was shown in his PSEC videos. It is much easier to understand, as it is in English.
   I beleve it is the same or similar process, as what Akula is doing now to find the best resonant coil frequency, I also think that is where that particular coil tuning method came from in the first place, which has now been adopted by Akula, on several if not all of his devices.
  As most of us don't have the proper equipment, such as an expensive spectrum analyzer, to find the best resonant frequency to tune to, this will have to be done by those that do have such test gear.
  Also keep in mind that a coil's self resonant frequency responce is not the same as what the Doc calls "Spacial Resonant Conhersion".
  I may not be able to properly explain this tuning concept, so I won't dare to try to do so, but I do believe it has everything to do with the Akula devices, and the how and why they ALL work as they do.  Also the reason that not one of US has been able to replicate any of his devices.

  Ben has made an overview of the PSEC tuning method, for those that have not seen it, you may find it interesting.

Some items of interest attached below:

Phase Locked Loop 4046 type data sheet
Hex Schmitt Trigger 7414 type data sheet

Link: A chapter from a very basic electronics text on using Inverter Gates (specifically hex Schmitt trigger gates) as oscillators

Note that in several Akula/Guk circuits there are gates of the inverter chip configured as oscillators, and the PLL chip is used in at least one of the circuits.

No, pin #5 is pin #5 - not a capacitor.
No, it is not necessary to create an intermediate frequency divider in order to o connect two chips with each other, but it is necessary if you want to run these two chips at different frequencies.

I think we have a language problem

Hi verpies,
Sorry I'm poor English.
I'm talking about is a circuit diagram Akula-Disassembly. . .

Hi All,
With the purpose of: Frequency stability for two chip TL494, will not be wrong frequency, each time the power supply to the circuit board, no need to adjust again! . . How synchronize two chips?

Acording to Verpies, you just need conect two 5 pins of two TL494 like that:
