Free Energy will change the World - Free Energy will stop Climate Change - Free Energy will give us hope
and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Stefan wanted that I have all these massive data to get it back online
even being as ill as Stefan is, he transferred all databases and folders

   I can get normal readings, such as in your questions, but, at times I can't.. As it can happen at the right duty cycle and best frequency and most optimal controller settings, is just where I sometimes have the messy bad signal problem. And believe me, there is a problem some where, and my guess is that it's the duty cycle circuit that is unstable. And when it fails, the whole device fails, by blowing the FETs, and overheating them. But I've made some changes, So, we'll see if there is any reduction of the FET and choke overheating still, or not.

Pin #3 is left unused, on this TL version. 12v at pins 8, 11, and 12.  4,90v on pins 9 and 10, when working properly,
Pin 13,14,15. 4.75v. Both pin 4 and pin 6 can be varied in voltage by the 20k and 50k trim pots. As I remember, from today's tests. Ground is on pin #1, 16, and 7. As in the pinoytech diagram that I've previously posted.
  Right now my rig is being put back together, but,  I'll post some voltage readings from the  TL494 IC, when I can.

Hmm! I don't suppose you have used the circuit with the 'dead time control' I found that only worked with the pulse width turned right down, and then if the pot was too close to the 4.5v the chip would shut down!  my advice is do not use it just takes up space and overrides the pulse width control, to do this I removed the pot a connected the wiper leg to 0 volts. Modulation only needs to be around 45 % no more.

Thanks for summarize this topic Saturnoi.

Still reading and hoping we can continue this path.
Unless i see Itsu spend many hours and has done a lot of testing and posting no clear result came out.

regards
Living in hope someone else finds the answer, what if meant suppose? well, what about the word assume? Is your device built differently or perhaps? you put one extra turn on a coil or the yoke had one extra 100 grains of FerroX compound?

Why not break it down and get the maximum out of what your building and now waste a drop of development fluid? look again at your driver and yoke or toroid tune it for maximum and does it's impedance match the grenade?

Regards AG
