Itsu:
   Ok, thanks for the video and advice. 
   Without the 28t coil and 168t coil and rectifier hooked up, it's hard to properly judge or compare the results.
   Your lumin levels would probably much higher on those bulbs if the 28t was also connected up. And possibly the heat on the snubbers, as well. In any case,  the heat on the snubbers (or lack of), was what we were really trying to show and understand.
So, it does look like the cleaner the square wave signal becomes, the less output it will provide.
   I do very much appreciated you helping me out in this way.

   Hoppy: 
   First I'll install the new carbon resistors that you recommended. Which I have now received. They only come to 1/2 watt size, so I'll have to use about 4 of them in series for the Oleg snubber, to get the 2 watts of resistance. And we'll see if the RC snubbers 1/2w 47ohm carbon resistors hold up, or not. I may have to double them up, as well.

  I have a lot more voltage and current going through my device, as compared to Itsu's test and video. My normal peaks with snubbers are over 200v at resonance. And at avalanche can get to over 350v. Which can partially light 600w worth of bulbs, or higher wattage, and this without going into the avalanche effect. So, that is probably why my snubber resistors get so much hotter.
But,  something may not be quite right on my set up, still. In any case, we'll see what happens when the new carbon resistors are installed.

  I now also have 10 more brand new Mosfets to play with. As well 4 new 4420 drivers chips of the right (through hole) size,
  Once I install the new resistors, I'll make another short video.

Nick,

If you parallel resistors, the resulting resistance will be reduced substantially. See this link for calculator: http://www.sengpielaudio.com/calculator-paralresist.htm

   Hoppy: Ok, then I'll install them in series. Error corrected now.
   Thanks for reminding me.

   AG: You mentioned:
"Nick
No offence Nick 'mate' but why doesn't your waveforms look like the one above?
                                                                                                              end quote.
   No offence taken, mate.
   All I can say is that that is like comparing apples to pears.
   Why don't you build a proper Ruslan/Akula/Stalker type of replication, then we can compare notes.
As as I've been going with Itsu.

Nick,

i have installed a 40W/220V bulb (which dimly glows) on the 28 turns (it has a 50V plus spike square wave on it), but it did not change anything much.

I changed the 1K Oleg snubber resistor for a 12K one and allthough the spikes got somewhat worse (from 100V to 170V), it hardly heats up now.
So you might want to try a higher Oleg snubber resistor yourself.

By the way, to double the wattage on your resistor (from ½W to 1W), you have to use 4 similar resistors, 2 parallel, and 2 in series.
If you want to go from ½W to 2W, then you need 16 of those, 4 in series and 4 parallel
If you want to keep the same Ohm value that is off course.



Itsu

Well, what's the difference all the devices work under the same principle unless you're referring to the yoke?

Well if you built a device with a yoke that yoke has to be a Russian yoke of military speck what I'm asking you is, is your and Itsu's device a Russian military spec device because I couldn't get one?

if it is where did you get it from and you need to ask your self why doesn't it work in your device correctly?
