I am trying to make some snubbers and I was thinking going with a varistor (MOV) 1k resistor and maybe a 100V NE-2 bulb as indicator for voltage spikes.

What size varistor should I get to protect the TL494 module and driving transistor? I got one 2n3055 to try out. I got no clue how much back EMF or spikes the oscillator&driver can take

   Itsu:
   I'll try to get some of the right resistors to see if they make a difference. As with just the snubber caps the fets get too warm on a 600w load. Plus the spike is still over 200v.
   I'll check the Kacher's interaction at the WIMA cap. But, I see no effect at the bulbs. None at all.

   How about you?  Are you going to attempt another try at the Kacher, with a line grounded to your house water pipe?
The ground connection is what keeps things from being destroyed. Just keep all the electronics away from the HV field.
   
   Void was right, there is no sign on the scope of the Kacher's HV interaction onto the induction circuits when turning on the Kacher circuit. That can also mean that there's something not right there. And that the right resonant point has not been achieved.
   I use an led as an field indicator next to the yoke to show me when I'm in resonance, and it has not turned on since the TL494 board was installed.

   Belfior:  You need to get the right mosfets for the induction circuits. The IRFP260N mosfets.  Get more of them than what you think that you'll need, as you'll go through a bunch of them before you get it right. And also the 0.47 WIMA caps, at least one or two of them, as well.
   Below is the circuit that I am using for my build. Along with some other schematics, like from Stalker.

I ordered 10 IRFP260N transistors, but don't know when they arrive. I got two 2N3055 HV transistor with heat sinks. What is the qualities we are looking for here? High voltage or speed or what?

Would this work for the cap?

Nick,

i tried yesterday, but my RC snubber resistors (carbon ½W) are not heating up while pulling 6A @ 24V (in resonance).
The only thing that heats up somewhat (50°C) is the Oleg 1K/2W snubber resistor, so it could be that your 460 Ohm is to low.

I also never had any visible interaction on the load bulbs when activating the kacher, only a DMM showed some volts increase.

I will not start with the kachers again, its not worth the risk.

Not sure what you  mean by: "I use an led as an field indicator next to the yoke to show me when I'm in resonance", what resonance are you talking about?
The kacher is always in resonance otherwise you won't have any output, and the inductor/wima cap series LC can easily been seen if its in resonance by
the bulbs (max. brightness).

Hi Belfior and Utopia Now. I am attaching a couple of older schematics that some people have experimented
with here. This should give you a starting point. Keep in mind that these circuits used in the Kapanadze/Daly/Akula/Ruslan
circuits can produce lethal voltages/currents, so build at your own risk (not sure what your experience is with electronics).

A couple of days ago, I was experimenting with a sparkgap flyback type driver circuit driving a coil, and I
moved the screwdriver tip of a plastic handled screwdriver close to one end of the coil to test the arcing distance,
and as I brought the tip of the screwdriver closer and closer to the end of the coil I got a major zap in my whole
right arm. The high voltage was inducing a quite strong current into my arm right through the plastic insulating handle
of the screwdriver and through my hand into my arm. The voltage on the end of the coil must have been pretty high
however as it was arcing to the ungrounded screwdriver tip a good inch before I got the shock. 
The input power to the flyback driver was only about 7.5 watts. From now on I will ground the screwdriver
when testing arc distances. 

The output of the PWM driver module with the series resonant loop can produce some high power as well, so that is why
I was previously cautioning GeoFusion not to work on these circuits on the cement in his bare feet.
You can potentially get lethal zaps out of these circuits if you are not careful, both from the tesla coil and from the
PWM driver module.
