   Could this be caused by the 50k pot being mounted backwards?
   Any ideas as to what to do about it?
   But,  I don't see a pause between the up and the down.
   Maybe you can show what it should look like.

No

Any ideas as to what to do about it?

Do not use the TL494  inputs that were intended for varying the dead time between the two push and pull channels.

But,  I don't see a pause between the up and the down.

I do and it's huge

Maybe you can show what it should look like.

PUSH: ____________|‾‾|____________|‾‾|____________|‾‾|____________

PULL:  _______________|‾‾|____________|‾‾|____________|‾‾|_________


versus


PUSH: ____________|‾‾|____________|‾‾|____________|‾‾|____________

PULL:  ____|‾‾|____________|‾‾|____________|‾‾|____________|‾‾|____


The push-pull (up-down) sequence^* supports one natural AC cycle of an LC resonant circuit.
Pauses between entire AC cycles are OK

CURRENT: ━━━━━━━━━━━┛‾‾|__┏━━━━━━━━━━━┛‾‾|__┏━━━━━━━━━━━┛‾‾|__┏━━━━━━━━━━━━━━━

...but it is unnatural to interrupt one cycle halfway.


^{* with minimal dead-time between push and pull periods, only to prevent shoot-through current through the push-pull driver}

Hi Wesley,

Did I miss that 3rd video of Denis Dniester with the shocking surprise?

   My input to the TL goes to pin 8,11, and 12.
Besides that,  there is a 0.1uf MKP X2 between the above mentioned pins and the ground at pin 7.

   As I am installing the fet driver circuit now,  I would like to get the huge off signal issue resolved.
   And I hope that this is not something wrong with my scope, other than blurry traces.

So connect it like this:
