Guys,  take care NOT to use a lab PS when tuning/testing your Kacher, use a battery or a simple 12/24V PS.
Last night one half of my double PS went out with a big bang while tuning my new kacher 
There is loads of RF going into your PS with the above result, the same warning i did read on the Russian forum last week or so.

Hi Itsu. That is likely why they have the special choke and filter caps in the kacher schematic.
I also blew one side of my bench power supply as well a couple months ago testing driving a
tesla coil with a FET pulser circuit. I fixed some components in the power supply, but the current
limiting is still not working correctly. Something still blown in there that I haven't been able to find. 
All the best...

Right,
i can see/measure these damaged parts, but there could be more invisible damaged under the hood 
2x MOSFET
4x 15V zeners
some fried PCB traces
Regards Itsu

Yikes. It helps in finding them when components are obviously blown like that,
but can be trickier to find other blown components that do not have outside surface damage.
I will have to do circuit tracing to see if I can find what is wrong in the current limiting circuitry.
Not always so easy trying to do that when you don't have a schematic. 
All the best...

I went back from my nano pulser circuit to the kacher circuit again to be more aligned with the present Ruslan setup.

I changed the antenna coil from copper tubing to a wider solid copper 6mm² wire.
I trimmed my kacher secondary down (only a few centimeters now) till it resonates around 2.1MHz when connected via a choke to the antenna coil.
The kacher circuit is the most simple one, without being synced by the TL494 and powered by a very simple PS 
I can change the voltage on the Kacher between 12V and 24V without any effect on the resonance frequency of the kacher, so it seems quite stable.

My multi turn coil has a resonance peak also around 2.1MHz thats why i trimmed the kacher to it, but all my tuning up till now did not result in sync
between the 26KHz / 220V pp signal on the bulbs and the kacher.

hi itsu,

Have you factored in the 60th Subharmonics of 2.1MhZ which now your circuit need to run at 35khz just be in sync.

If you do a scope ref save base on your current setup at 2.1Mhz and if you are still sticking with 26.1khz.You will definitely noticed that both your waveform will not be aligned at all.
Maybe simple solution for you now is to slowly increase the yoke driver frequency to 35khz and observe if there is any increase in brightness without the nanopulse generator.

I have attached the harmonics calculator once more with your 2.1Mhz in it and please take a look at 60th Subharmonics as rough guide.

You do have the gift in producing elegant setup with the proper tools and  a nice bench but it would be pointless if you don't strictly follow the rules of harmonics as a guideline."Please don't be offended"

Ruslan did mention somewhere in forum do not use the spectrum analyzer for the multilayer coil.
At 60th Subharmonics if you got my point.

"Dear all this is not a science fair project provided if you realized this by now.I even noticed some of you don't even care about the spacing for the outer layer and simply wind this directly thick wire onto the coil.The reason for the spacing is to ensure the tesla coil resonance will not be tampered with if there is load eg:bulb.Provided if you are still serious in creating this device.This project is not about who finish first it's far more than that"

Hi Itsu

Yes looks simple but is not simple - never been simple !!

I have forgot to tell - you should take in account the lenght of your coaxial cable. Several cm more or less and effect would vanish. Very tiny waveguide processes are here and very hard to catch.
You can use your lab PS but need to isolate your PS output with power diodes from other HV circuit like Ruslan has shown in his video. Also use any line filter from old computer PS and decouple both supply rails with respect to the ground. Bypass with lot of caps from 4700 uf/50V to 1kV 1nf bipolar capacitors. You will find all parts in old computer PC.  Also you can remade old PS to give you 24V/10...20A for use with generator.

Hi Jeg

You are man of dreams. 

Answer for you is - just like shown i pictures. I put them in high resolution with intention. Analyse pictures - they will give you many answers. Resonant Capacitor is realy needed. His value is something more than 1uf/2kV. You can find it in old microwave oven. About measuring HV  - never put your oscilloscope probes on HV conductors or you will burn both. If you need to scope HV signals put old good rod antenna to oscilloscope 50 ohms input and tune sensitivity and time base. You will catch them easy at distance of several meters. this worth also for spetral analysers and frequency counters. 1m rod antenna from old radio will save your scope and other equipment.

Hi Hoppy

16mm² earth cable and 2m earthed cooper rod is Ruslan recommendation from interview.

Forums are for sharing useful informations not speculations. I use principle from slogan"Take It or Leave It".

Problem is in this: Nobody on this planet knows how to correctly extract free energy from ambient and does not know about hidden physical process involved. This worth starting from Official Nobel prize winners to simple people which make experiments in attempt to get some results. Understanding of principles is most important - but how can you thought about tyny processes without informations collected from own and other people experiments ??

Those people which have self running device - for sure not sit of forums and flood and spam.

Hi Enjoykin. I wasn't commenting on people sharing their ideas and experience. Sharing ideas and experience
is a good thing. It is the comments where people are saying you must do this and you must do that rather
than they have an idea that this might possibly be better, or maybe things are possibly working like this or maybe like that.
A big difference. It's all about how it is presented. For myself anyway, until I see a working device from someone
I will definitely take anything being stated as an absolute as just some ideas which may be true or maybe partially true,
or which may actually be quite false. I know for myself that every time I think that I am starting to understand
how at least part of this device might work, I do further experiments and then I am not so sure again. 
All the best...
