You mean in terms of harmonics? Without sync no effect?

Well, if you did read and understood N. Tesla quote there is specific term to reach effect...
Without sync you won't have any "fireballs"/burning/free energy.

It would be good to show just what the yoke/grenade coils can do to a single bulb (100w-500w bulb), without the Kacher connected. Then to show the difference in bulb brightness with the Kacher working also.
  If the yoke/grenade by itself is only barely lighting the bulb(s), I don't see how the Kacher pulses are going to do much to improve that, toward producing an output of 1000w to 2200w.
 Also, wasn't the idea previously, that the magnetic induction crt output was to be superimposed by DC voltage from the kacher crt? Not AC? 
As,  I have also noticed higher bulb brightness when superimposing the Kacher's output through a rectifier diode as half wave DC.

  NOTE: I did notice a difference when the ferrite rod with the two small opposite wound coils are used. The kacher's output becomes more intense, RF burns , when previously no RF burns were felt. I would say that the voltage drops, but  the amperage is raised, and of course this changes the running frequency of the Kacher, at the antenna.  Just thought that I'd mention that, again, as some of you don't seam to be noticing much difference from the ferrite rod tuner coils.
However the bulb brightness only improved slightly in my case, when connecting through the ferrite rod.  But, noticeably.

  It would also be good to know just how and where to connect the 3 fans, to the circuit's input. Be it to 12v, or 24v circuits.

hi Nickz,

Although i am able to achieve maximum bulb brightness at 60watt at L/C resonance at pwm around 12.98khz for load testing purpose to see how my component eg:IGBT can handle.
I choose not to talk about it because it got everything to do with kacher no L/C resonance should be involved here.

If you study the circuit diagram the kacher antenna is directly over the 25 turns bifilar which the top bifilar is connected to earth.
Kacher secondary is already connected to earth via base of transistor and also via TVS diode 18volts bi-directional.Upon hitting this voltage of tvs it is connected to earth as well.

What i am trying to say kacher antenna over 25turns is similar to closing the loop and back to earth but without direct contact involved.

The L/C resonance i believe should be pre-tuned in advance using suitable capacitor.But the actual pwm generator would be running at twice the L/C frequency around eg:26khz be it 50th or 60th sub-harmonics version.

Of course at 50th sub-harmonics version the pwm generator would be running at around 32khz....37khz if compared to kacher frequency which was derive from mutlilayer coil resonance.

You are are right about the kacher the spark is more intense like little red (little more current flow) rather than more blue after the additional windings after the tesla coil.Recall the Ruslan video where i noticed and mentioned the spark was little reddish in colour.

---------------------------
There are some parts of my experiment which i am lost for words on how to describe.For example i was playing with ferrite rod insertion into kacher which for my case it would impact pwm generator accordingly(This is how my circuit is configured via antenna).Then at the certain frequency of kacher this suddenly drops to 12.98khz between capacitor.But i know my pwm generator is running at higher frequency."I got no explanation for now" .This is where i noticed there is slight drop in amps while bulb brightness is maintained.Take note i am using diode at center tap of toroid for a reason which will be too long to talk about it."Just picture this as the diode after PSU unit in Ruslan device"

Theoretically it should?  the self inductance from the start of current flow in the one end should make current flow complimentarily in the other end.... but it takes times of domains in the ferrite to flip?  maybe I don't have a long enough delay line in mine?  (it's kinda a short bar)

Hi d3x0r. I really don't know how it should work, or if it really does work as claimed at all.  I think it's good to try to
understand conceptually how various things might be working, but the way I look at it is that it is all just ideas however
until we can demonstrate a given concept practically in an actual circuit, and show clearly how the concept applies in actual
changes in working functionality in a circuit.
All the best...

Hi Nick. From my own testing so far with this, what you may be seeing in regards to the output of the kacher seeming
to burn more with the ferrite rod with its opposing windings in place on the output of the kacher, is that adding
this rod and windings in place will probably lower the frequency of your kacher/tesla coil at least somewhat. Different frequencies
will tend to produce different types of corona discharge with different characteristics. In some cases the differences
may be very minor, but in other cases it can be quite a noticeable difference. I am still experimenting with this myself as well.
 
There may well be other effects introduced by this ferrite rod with opposing windings, but I think it may help
to keep in mind that Ruslan's 12V device did not include this piece and it apparently was still working well, from what could
be gathered from the videos anyway. Ruslan apparently decided to replicate Akula's second self runner much more closely with
his 24V device, so he added the ferrite rod and opposing windings, but I have to wonder how much effect/improvement it
really has. Ruslan was previously translated as saying that you may or may not need this ferrite rod to get things working.

Regarding the fans, you should be able to just connect them to the output of the power supply which loops the
output back to the input. If you have a 12V power supply, use 12V fans. If you are using 24V, then use 24V fans.

All the best...

Every bit of info is valuable king21. Everything points at the same method.

I started few hours ago to build a new Katcher coil, and I still can't tune it at 1Mhz. I put or extract turns, but frequency seems to jump from 980Khz to 1.2Mhz. I put few turns more and then again at 980Khz. Really strange. My previous coil tuned in 10 mins!

Jeg,

I have found that as I approach the grenade coil 1/4 wave resonant frequency, my kacher frequency will jump between two frequencies much like yours is doing, with one of these frequencies tending to lock-on, which is the one I tune to.

Well guys,

I just started to draw my Push Pull and the first what I noticed is the negative terminal on the Drain of the Mosfet. To make it more confused Enjoyiking supplied some schematic with the N-channel Mosfets (ground on drain??)  and Ruslan's original drawing seen in his YouTube video has drawn P-Channel mosfet but with N-channel type number. What the heck??

Ok , lets, believe it is N-channel- should ground be on the drain as on the picture??


Thanks.

Itsu or others, ifyou want, you can try new schematic.
This schematic works without ground and it selfrunning. Maybe about 10-50 W power output.

What writen in green is 50 Herc resonance. That in blue, that LC circuit must be on 470 kiloherc resonance.
Pusch pull for 50 herc can be any and for 470 kiloherc (higher frenquency also can be and it better) generator also can be any.Transistors for low frenquency (but it can be and not 50 herc, can be and maybe 4 kiloherc) can be IRFZ44n. For hight frenquency IRF640N.TLC is wounded on ferite core. C11 not is, here mistake. Diode D1 is fife diodes in parralel, but inaft can be and with 3. C10 must be chosen for resonance 400-500 kiloherc. If you interest thisschematic, then I give you more details and answer to your questions if you have them.
