   Void and Itsu:
   Thanks for the tip about the voltages. I guess that when ever I press the AUTO button, it changes the setting back to default voltages.  So, I just needed to change it back to where it was. I was focusing on the frequency readings and didn't see that the voltages had changed.

   Itsu:  I've made some orders to Mouser.com. But, won't get the resistors, and other components until after the 22nd of Sept.
   But, there are no bigger wattage value carbon resistors there, over the 1/2 watt size. So I ordered several of the 47 ohm, and 1k ohm, of the 1/2 watt size. Maybe they can be added together in series, or parallel placements.

WooHoo!

Did that scope finally find you Nick?


Hey, something to think about with y'alls yoke cores...

Square ferrite.  If you don't know what that means, watch this video

I recall seeing those waveforms on Ruslan's scope and wasn't able to
relate it to something I was familiar with.  Now I recognize it.

Yes, I think this is where Ruslan was monitoring the current waveform in the series resonant yoke winding by using a small toroid core, allowed to saturate by virtue of the high series current and sufficient ampere turns. The sharpness and amplitude of the 'moustache' shaped waveform spikes give a good indication of approaching resonance.

Oh! well done. I have heard it said that the 'cores; are originally barium based military grade that has been originally used, so to try and say what device to look for in the core material in the data sheet and how to set it up, I wish you all luck.

PS I used your fishing line air gap with good results thanks very much for that one .

   Dog-One:
   Yes, it finally came!!!  I had to make an all day trip to pick it up at customs, they only charged 20 dollars at customs. They thought that it was a new scope still in the original box. I had to convince they that it was not new. When it was.
   It made it here in perfect condition.  I had made a post to you here on the forum when I got it, but I guess that you didn't see it.
   Thank so much again, Dog-One.

   Itsu: I been playing around with different snubber caps and resistors, and have managed to drop the peaks a bit, as well as the heat on the snubber resistors, and also the fets are staying somewhat cooler now.
   I also added a 0.1uf WIMA cap in parallel onto the grenade's output coil, which had not been used lately. This helped to reduce the high peaks, and mellow out the heat issue.
   I always use a magnetite magnet onto the ferrite yoke core, to fine tune the device with. And have always done so.
 
   As we don't really have any proper tuning instruction, perhaps I can show how to go about it, once I learn the ropes.

   Using both scopes, and a CT on the 3t induction circuit, I adjust for the maximum output from the small CT torroid, but it usually is not where the best output at the bulbs is at. So, I'm hoping that the Kacher's HV will make up for the difference, and will allow the device to receive Radio Moscow, again. As it's gotten a bit harder to find, when dropping the voltages under 200v.
