  This is the video of our original type of driver circuits by Ruslan, (Oleg), showing the current transformer and scope shots, also.
I believe this video, is what you were looking for.

  Although I had installed the 12v and 15v voltage regulators and their associated filter caps, to the TL/TC circuits.
But, I did not installed the filter caps that go to the yoke center tap. This I've done now. Along with adding a choke to my TL494/TC4420 gate driver circuits. Which I had neglected to do, previously.
  My entire device is being re-worked, at this time.

    Here is new video showing what my TL494/UC4420 driver signals look like. It's the first test using just a 12v battery, instead of my 24v power supply. I wanted to be sure that it's not my PSU interference messing up my driver's signals on the scope. However, there does seam to be something wrong on my TL494 circuit. Might be a damaged 20k pot,  or maybe not.
What do you think, or can suggest?

Nick,

I may be wrong but it looked like your scope lost synch at the point where you first reduced the duty cycle.

I may be wrong but it looked like your scope lost synch at the point where you first reduced the duty cycle.

Yes and this is most likely caused by the scope being set to AC coupling (the channel or the trigger)...it should be DC coupled.

Nick, get off your butt and fix that focus control on your scope. Tinsel Koala gave you such nice directions once....
Bad focus obscures the fine details of the waveform and makes me unenthusiastic about helping you ...could be that others react the same way, too.
