Kapanadze Cousin - DALLY FREE ENERGY

Sorry, no, that scopeshot is uninterpretable, except as proof that he actually does have an oscilloscope.

We would like to see something like this. I have deliberately de-focussed my scope to simulate Nick's but the photo itself is properly focussed. The traces are clear enough to be able to tell what is going on.

Note that I have placed the channel baselines on graticule lines and I have indicated where CH1 and CH2 baselines are with tape flags. Traces obtained with 2v/div and 500 us/div. 

Note that you can read: Pulse shape, pulse peak voltage, pulse frequency for each channel, and phase (delay) difference, and dead time for the two channels together.

   OK, I can do that, no problem there, but my image is not steady, and will not look like yours. However, even on a blurry image I can tell that the problem is that both FETs are On at the same time. No dead time control function.
   I don' think that there are any shorts, cold solder joints, etz... But, there maybe something wrong in the schematic  that I'm following itself. As Verpies has mentioned previously.
   I would like to try this method (below) for the duty cycle part of the circuit next. Pinoy's design, going after the topruslan style. TL494 pin 3 is left open. As I have not tried that, yet. Who knows it might work for me.
   What do you think?

the internal structure of the 494. Note the two outputs are fed by a 'D' type device its a flip flop both outputs can't be on at the same time unless it's 'blown'.

No, the two outputs are fed by NOR gates preceded by AND gates and both outputs can be ON at the same time when the ctrl input feeding the AND gates, is at zero logic level.
