Kapanadze Cousin - DALLY FREE ENERGY

Hi Hoppy. I think some people have reported a grenade resonance point around there.
All the best...

Yes, thanks Void, you have jogged my memory. Interestingly, we do not see the effect demonstrated by URFA in any of Ruslan's videos.

At katcher side did you disconnect the 1000uF cap after the choke or you didn't have any with so much capacity?

Jeg,

I have not removed the 1000uF cap shown after the Kacher common-mode choke (not fitted on my device) However, I found it important to remove the electrolytic cap after the push-pull filter choke and replace with a non-polarised cap around 1uF. This has the effect of reducing the amplitude of the leading edge of the push-pull pulse waveform and maximising bulb brightness. This electrolytic cap (470uF in my case) severely attenuates bulb brightness on my setup.

Thanks a lot Hoppy. I will proceed the same. I already dismounted katcher for surgery.

Guys, I have got a time to test my push pull and the first observation is one of my Mosfets warms up more than other. Have you got the same?

Some thought about the inductor on the grenade:  by careful listening to what exactly Ruslan said abut it" ...first we wound first layer , back with the wire and than second layer" -  no mention of the third layer.

next his words " to make an inductor, we USUALLY take a half of the length of the grenade coil"  -   If I understood right,  that USUALLY means not necessary. And it is more clear when you use grounding which is extension of the grenade but your inductor stays the same length.

Also,my comment to idea of using the tube antenna  instead of coil antenna. There is something I do not like about the coil and it is its free end. It is like a wire- streamer. Something Tesla didn't like because the stream is waste of energy. The tube has sharp edges too. What I would propose is to use the torus around the grenade.
Also guys, we might maybe to perform some Skype session as Russians do   what you say

   John.K1:
   I always have had the problem with one or the other fet always getting hotter than the other one. Especially when lighting 5 to 7, 100 watt bulbs.
  I think that some or maybe even most of the guys will notice this overheating as well, when trying to light some REAL loads.
As yet, none of us has made a circuit that can light 1000 to 2000 watts, as Akula/Ruslan have shown possible. Nor are they really outputting that high a load, as all their bulbs will dim somewhat, as each additional bulb is added to the circuit. That is probably why they don't show what a similar bulb does when connected to the grid, and placed next to their circuit, to show the lumin comparison. 

  I also thought that the free end of the kacher antenna may not be the best way to go, and tried to place my Joule Ringer core directly on top of the yoke, and fed the HV output from that ringer core to light a CFL bulb, (to test the HV output) which was also then connected to directly to the grenade. But, no real additional effect was observed, with or without the CFL lighting, and also connected as well, which was lighting pretty brightly.
