-on some of the films Ruslan system uses the system to sync where he hooked? (or plugged it straight to the comparator?)
if anyone can do the trick suggest something how do I connect whether it is worthwhile to check it out?

  Dog:
  I've also changed some more components, thinking there must be something wrong with one of them. So, I replaced both 10k resistors, with new ones, and replaced the two cross-over diodes again, to two IN5398, this time. 
Same thing, still overheating... But, if I don't connect the grenade's output coil, and just run the 3 turns coil/inductor circuit, there is no heating at all. This is also using brand new fets, which seam to working ok. Nice clean wave forms on the scope, from both fets, although one of fets has a slightly higher output, than the other one. I'll show it once I get this heating issue solved, and can get back to tuning.

Nick,

Do you have a ferrite core in your grenade coil. If so, how is the heating affected when you remove the ferrite?

Good day Tomtech29

  Hoppy:
   I've always had ferrite pieces in my grenade former tube, as that's how I tune the frequency. But, I've never had this type of intense overheating. It's seams that the Mazilli driver is fine, but there may be something wrong with the 28 turns on the yoke. As everything is fine until I connect up that coil to the grenade. Then the system is heavily loaded, even without a load from the bulbs.
  As this is a new 24v yoke coils system. There may be something wrong there, like possibly wrong winding direction, maybe.
I wound the new yoke coils with the primary coil and 28 turns secondary coil, and the 3 turns coil (6 turns now), on this yoke ALL in a clockwise direction. But, my older 12v yoke coil was wound with the 3 turns coil opposite (CCW) the other two yoke coils which are CW.
  With of without ferrite tuning cores inside of the grenade, same thing, still the same amount of heat on the fets.
Actually, I have not been using the ferrite inside the grenade, at this time. So, it is not the cause of the heating.

Hi
I was a little odejde with the subject from the conventional version TL494 going trace Ruslan I tried a chip SG3525A.
and the system works but I had to make some changes and still I can not find the cause of the inclined front view: OSC_OUT_KEY.
I thought it was the voltage drop across the resistor, but the cause lies somewhere? the mode when I mentioned potentiometers to 600K. I have more regulations but the time range of pulses varies saw more in shape.

Good day Tomtech29

In regards to the  slow rising edge on the sg3525 generated waveform:

1. Try a different driver; ie IXSY609,  IXDN614 etc, these all have superfast Schmidt waveform shapers at the input, will clean up almost any slow rising edge.

2. SG3525 is mostly used at lower frequencies, ie: DC/AC inverters @ 35-55kHz.  I personally have used the  *faster* SG3825AN to replace it, although it is NOT a direct drop replacement. Must re-route the pcb. 

3. For a fast rising edge/cleaner signal the CD4046BE configured as a simple VCO will work into the MHz range.

4. For an even faster and consistant rise/fall time, (30-35ns) see o-scope shot attached:   AD9850_dds, will work up to 40MHz with proper layout/design.  This o-scope shot is from an galvanically isolated GDT running SiCmosfets.

take care, peace
