Itsu:
   On further testing I found that the small 1/2 watt 56 ohm carbon resistor I placed for the fet snubber can't handle the higher loads, and started smoking. So, although it still works, but needs to be replaced by a higher value one.

    The bad news is that there is NO interaction from the Kacher. None. It does nothing to brighten up the bulbs. The Kacher has 5 to  6mm streamers, so it's working ok, but I see no improvement with it on. Same as in your last video before you turned in your towel, and gave up on it.

    It's the same everything (Kacher/grenade/yoke/rectifier, etz) that I had on there before I changed to the TL494 driver circuit. And even going through the whole frequency ranges does nothing to improve the interaction. Nor does the duty cycle controls help, either.
    So...  don't know what to do about that.  Something may be wrong there, but I don't know what.
    Anyways, I'll keep at it, and will continue looking for the solution.

Well done Nick, you've now reached base camp. Its all uphill from there.

Hoppy tunning could the problem with streamers and the reason the bulbs don't get brighter be because your grenade frequency of resonance and your katcher resonance are not the same wavelength or harmonic which ever the case might be, other wise the grenade would suck the energy and the katcher would be quite dry due to the resonance would it not ?

as an after thought what is the output of the grenade like and it's frequency have a look at that (but use an attenuated scope probe).

On another subject please notice the winding of this grenade coil winding, notice the layer length I wound a test coil like this and had a much better result.

Not sure if this is the right thread but hope it helps.

   Good thing... I brought a bag full of Snickers for the rest of the trip. Hoping to make it to the top, before winter comes.

I assume this post is for Nick's attention, as I dont currently have a build.
