I just completed my construction of the TL494 + TC4420 halfbridge driver board. Seems to work fine so far. ...

Nice job!

Thanks!

My new videos aren't really relevant to this thread, but this one may be of general interest anyway, especially since it has gotten my trolls to post their 5 thumbs-downs already:

Meanwhile, I've been testing the 494 driver board using a small pot-core stepup transformer and a neon as load. I'm either connecting one end of the pot-core Primary to both drains and the other end of the Primary to the positive supply rail. Or, I'll connect each end of the Primary to a Drain and the Center Tap of the Primary to the positive supply rail.

In the scopeshot below CH1 and CH2 are the Gate signals from the twin 4420 chips, and CH3 is the common Drain signal using the first potcore hookup. (Remember Drain goes LOW when mosfets are ON). I have found that tuning can be tricky, in that sometimes one or the other of the 494 outputs collapses to a spike instead of a rectangular pulse. This may present a problem if one tries to tune without using the oscilloscope.

The Drain Snubbers using 22R 2W + 0.01 uF 1kV  are working well to absorb nastiness that could heat up and or damage the mosfets. I'm using IRF3205 mosfets and they are working well with the loads I have tried. Have not damaged anything in several hours of testing in all kinds of load conditions and current draw. (I have my PSU set to limit current at around 3 amps though.)

I have also installed a switch whereby I can select one of three different Timing Capacitors so I can cover a very broad frequency range. (Not shown on the Layout diagram.)

This is basically the Stalker circuit with the addition of the 1k pulldown resistors for the 494 open-collector outputs, and the Snubbers on each mosfet Drain, and the switch for Timing Capacitor choices.

Posted the following in another form a few days back but it is likely relevant here as well. Food for thought!

F.Y.I.

In the real world progressing from a great idea to a viable product, believe it or not, can be
relatively easy, a lot of fun and quite interesting. Developing a "new type of fuel-less generator"
has an added bonus in that it can be done semi-professionally at relative low cost.

Briefly, an example scenario:

There are two development roads one can follow. Either the (a) iterative "cut and try" method, or,
what I'll term, (b) the mathematical engineering physics route; or preferably a healthy slice of both
(a) plus (b).

Following only the (a) road, in my opinion, is quite valuable but quickly leads to a brick wall dead
end. Youtube is littered with videos of coils and light bulbs including, in some rare cases,
researchers attempting to educate other "seekers-of-knowledge" using a variety of primitive "aids" and
"self derived" gibberish. Out of the many thousands of videos and comment pages there are but a hand
full of "useful" demonstrations; and, more often than not, when their goal is reached the presenter moves
on to further (usually very quiet retirement) development. Without the (b) route there is generally not much in the
way of "value" to be had. We have all observed this over the years. I will address (b) further in a bit.

Physical Hardware and T&M Equipment:

Device hardware; that is, for wire, electronic components, brass-board, enclosure, and so forth the expenditures
are minimal; likely less than a dining out for two with desert and drinks!

Fundamental design Test Equipment; an old laptop, (isolated) USB PC Oscilloscope, digital meter,
and battery again can be procured now days at very low cost. High voltage probes and other exotic
measurement devices can be easily fabricated with a little ingenuity.

Engineering Physics Tools (mathematics - multiphysics Computer Aided Engineering [CAE]):

Much, if not all, of the "alternate" energy theory, in my opinion, can be uncovered and disclosed
using conventional science with the assistance of modern engineering and physics tools that
are just now becoming available to us; the (b) route . Here are a few of the many examples:

Simulation Software: A Price and Performance for Everyone

Multiphysics for the masses. COMSOL wants to democratize simulation in the design processâ€" TV-report > ENGINEERING.com

https://www.comsol.com/products

Gaining access to these tools can be cost effective as well - take a course at your local educational
institute; invest in an "off lease or surplus" HP Z820 Workstation; obtain demo or student versions
of CAE software; put a business plan together and run it by your banker or rich uncle... A maybe "unseen
additional bonus" involves developing a valuable "skill set" that can be applied in many other disciplines.

There is enough valid evidence of viable alternate energy devices but to make it actually happen
we need to do something besides light bulbs on Youtube, bicker about who's theory is correct or
what "method or technique" is the best.

With minimal expense and a little diligent effort, I firmly believe following the (b) route will bring
success for all and, if not right away, it will be fun and very educational at worst.

Plus; I see enough intelligence out here, I'm optimistic we can do it... we do however need a
forum board where you can publish formulas and other science material in a usable fashion.

Thanks for reading! 
PS - My new 32 core servers arrive tomorrow so I too will now also "move to a very quiet retirement" [development].

For many on the fora, tinkering around with electronic components and associated test equipment and software to develop skills in practical electronics is the primary source of enjoyment. The assumed primary purpose for doing this - to build a free energy device - for many, eventually becomes of secondary importance I would suggest.

[NickZ]

   However, as fun or educational as tinkering with electronics may be, it would really be nice to build a self running device that works. Instead of spending thousands of hours, months and years, without anything useful to show for it. Some positive results would also provide us with further motivation to continue in the future.
In any case,  I'm dedicated to this cause, and will stick with it, come hell or high waters. As that is what I came to this world to re- discover, re-invent, and improve apon, once it's working.  And I will get it working.
   Thanks to all for your help and cooperation. We are a team, and a good one at that. Regardless of results.

  TK:  I'll study your circuit and get back to you on it a little later. Thanks for posting it.
