Simple to build isolation transformer that consumes less power than it gives out

[Jack Noskills]

Could this project be run using a pair of toroids instead of the regualr trandformers?

Yes, what ever core material you have can be used, you only need to find correct combination of coil length, or coil length and amount of parallel capacitance. Divide toroid in two logical halves and wind coils on it, one on each side exact same amount of turns. This needs to be high self inductance at lower frequencies so it blocks current flow, or you can parallel caps in the first coil to block your grid frequency. So this is a trade off between amount of caps and coil length. I have explained this earlier, you should find better answer there.

One more picture to wrap up the first phase of replication in order to avoid any misunderstandings.

And beware, if coils are in wrong way you will get all the power trafo can give times two in the source, so find correct position of lower coil using cap or light bulb as current limiter first. If you need to tune, remove current limiter if you are not using a cap.

John go borrow a meter from someone you know and then come back with the numbers
and if they are good I'll get excited and start building too.
I already wasted too much time on somebody else's good idea that did not work.
I have other things on my plate to do now.

barotolougos already duplicated, though not highest efficiency because of high idle current. With a bit of math and finding correct parallel cap he will get it right and happy days for us all.

Trust me, this is the real deal. Or I am blind and cannot feel heat difference of two similar light bulbs correctly. One burns my hand while other is cold. You don't have to attempt to duplicate if you dont want to, lets enjoy the summer time.

Jack,

Please post a picture of your circuit build.

Thank you.
