   Itsu:
   As both of the smaller 56 ohm carbon snubber resistor went up in smoke, I replaced it with a 3 watt 56 ohm unknown type of resistor. It's sort of a pink/tan color. May be wire wound, but I don't know.
   Any way, even that bigger 3 watt resistor overheats just the same as the smaller one had done. And is untouchable in less than a minutes running time.
   Any ideas as to what to do about it. Do your resistors get hot, as well?
   Still no interaction from my Kacher onto the induction circuits.
   
   One thing that I've learned by working on my set up is that the earth ground line will only really do something, if the rest of the system is really in resonance. Otherwise there is NO effect from the ground lines.
   I have two 37.5 meter long Earth ground lines going into my water well that's in my back yard. But, now I don't notice any improvement when I connect it up to the device. This tell me that the device is NOT in resonance, no matter how I turn the TL 494 controllers. There has been no change in my Kacher or grenade since the TL494 replaced the Mazilli driver.

Nick,

no, i use ½w resistors and they won't heat up, but mine are 180 Ohm ones.
Did they also heat up when NOT using the Oleg spike snubber?

  Itsu:
  I don't think that they heat up without the Oleg snubber on.
  I'll disconnect the Oleg snubber and see if the 3w resistors heat up, or not, without that snubber on.

Nick,

IMO a better solution would be to use a TVS diode (drain to source) with a power rating of say 1500W and a clamping voltage (not breakdown voltage) rating V_c of safely under the minimum breakdown voltage rating of your mosfets.

Ok, if they do not heat up without the Oleg snubbers, then i think something is wrong with the Oleg snubber.
Remembering you strange voltage levels on the drains (50V with 12V supply etc.) aids in that.
Either the components are not suitable (wire wound resistor, inferiour cap) or you have wired them up wrongly somehow.

Double check on their connections.

You might want to switch to TVS diodes instead of the Oleg snubber as suggested by Hoppy.
