Would be a little easier to see the similarities if I could understand what he was saying about the Hendershot diagram. How 'bout a hand? 

  So, is the choke inside the akula device's big secondary coil, connected only to a cap, and nothing else?  Seams like it could have the same function as the Dally coax cable that is shorted at the end. Yes, No? Maybe?
 

Akula's device is said to be like Hendershot.  But only one side of Hendershot device, half of Hendershot, only one large coil where Hendershot has 2 large coils.
According to Hendershot schematics and pictures of Hendershot device, inside of large coil is a handmade capacitor connected to a coil and nothing else. Same as Akula shows in the middle of his hand drawn schematic.  A coil and capacitor connected to each other and nothing else. A tank circuit that is tuned to oscillate at a certain frequency. 
Hendershot used aluminum sheet inside his coil form also.  He also used aluminum sheets to make his own capacitor that was inside the large coil.
Just do a search on Hendershot.  There's plenty of information on his device.

Hi Nick. If you watch the top of the air core coil assembly closely in the Akula video, you can see in many frames that there is what really appears to be an aluminum sheet wrapped around the outside of the coil form under all the windings. The aluminum sheeting (or some other shiny silver colored metal) is sticking out at the top of the coil form. The aluminum sheeting appears to be possibly folded over the top of the coil form at the top inside edge. This would seem to be at least part of what Akula was referring to in regards to the Hendershot generator, which has the two main coil forms around home made metal cylindrical capacitors.

I have attached some screen shots, but I think it is quite obvious in the Akula video if you watch closely. There appears to be quite a wide gap in the aluminum sheeting at the back side of the coil form of about roughly 2 to 3 inches.

I think in Akula divice maybe no aliuminium sheet, this maybe be isolation who looks like aliuminium.

White wire, who gose to lamps seems must have about 40 windings.

You will find http://imgbin.org/index.php?page=image&id=13184 in Hendershot circuit on left and right for opposite polarities. This is why I pointed to Romanov's video... Also I seen this part in other circuits expressing unusual OU like effects.

Explanation of Romanoff is not obvious, point of  mous is not visible, i am not trust such explanation because Romanoff not did clone of Lestor Hendershot Mark 2 generator yet.
These explanation just his (Romaniff) own fantasys.

Remembering how you tried with trolling everyone and towards making drama in Kapanadze/D. Smith threads with intention to anger tiger2007 towards me and my team in yoke case, I still consider this as another troll post. So, "don't feed the troll" - http://rationalwiki.org/wiki/Don%27t_feed_the_Troll

    @MenofFather:
     Thank you taking the time to draw your diagram. I will study it further and consider it, along with T-1000's diagram that he posted. 
    Sorry about my comments concerning Romanov's explanation, I'll review the ideas, avoiding judgements. Still would be nice to know what he is saying...

    I'm fresh out of peanuts. So, not to worry.

    Dllabarre:  Amazing shot! 

    @ T-1000 or anyone, I think that this picture (below) comes from one of the Russian guys. It may be showing the simple mode of operation of some of these devices. What do you think about it?

...your task is to disconnect step up transformer before this happens so entire stored energy goes into load not power source...

That's also a good advice for powering Flyback Transformers.

@Nickz Thanks for the link, How is your experimental work (akula device) going on...Any improvements is there. Ok All the best Nick......

 
   My work is going slow, as I'm trying to figure out what to do, before I do it, thus trying to avoid useless work, and lost time. I don't mind doing something new and innovative, but, I do mind wasting time at useless ventures.
   I am still experimenting on the aluminum tube (choke) inside of an Exciter that is connected to the pulse circuit that I previously shown. To get some idea what it does, and if and how I can apply that to the Akula type device. Knowing about the wire turn count, gauge, and cap specs, would help. Which is what leads me to further study previous projects, that led to this last Akula device.

   So far, I can see that I can light a neon bulb (off of the choke tube), as well as CFLs, even by just touching it without the use of a cap in series. As I don't know what cap to use, so it's time consuming process of testing and elimination.
  Also, I'm trying to avoid the use of  spark gaps, at all costs, now that I see that Akula did not need to use any. He does show a transistor looking component, with only two legs, which might be a special diode of some kind, but might not be, also.
  This device is the first self runner that I've seen working without a spark gap, well almost the first. Although, I'm not the most informed guy, and came in late into the game, after many others tried and failed.  But, I'm determined not to follows in their tracks.
  Sorry for the long boring reply...  Well, at least I'm not bored, any ways...
