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.

   Happy.
  It's going slow,  but steady.  I'm using mostly all recycled components.

Yes, take it steady. Check & double check connections are correct. If possible use an IC holder / socket for your TL494 as changing a chip, if needed, with the type of board you are using is messy!

   Yes, the socket IC holder would really help, I'll install it if I need to replace the TL 494 chip.

   I'm nearly ready to add the fet drivers, and snubbers, next. All to be installed on that single PCB. No long connection wires.

Nick,

Tip: Test each circuit element as you proceed. Don't just connect everything together and wonder why it doesn't work or a component smokes! Firstly test that the voltage regulator(s) is functioning correctly before connecting power to the TL494. With the TL494 in circuit, test the frequency and duty controls by scoping the outputs for the correct waveforms. Then connect and test the FET drivers and scope for correct waveforms before connecting the FET's and snubbers to supply rail and load.
