Pulsed signal 60% more effective then strait DC

Steve said he used true rms meters and the result was the same

so there's more power out than in?

I didn't build the setup yet.Hidro or Steve can answer that.

Some with a ferriet core and bifilar winding works.
I used two different types and both worked.
1: single layer bif 1mm wire, 100 windings on 1cm diam core.
2: 0,5mm wire bif on half moon core of old tv tube.
I dont have the specs from PT, but he used higher volts, big tube, 20cm diam toroid core..

With my tests on the joulethief i found out that twisted wire bifilar works great too.

I made the test today of the bifiliar setup.100t ,1mm wire  diam.and the choke made it worst,it acted like a resistor restricting half of the amps but also half of the voltage.power consumption was the same before the choke and after(0.25A).maybe i need to add some koh to make it draw more curent.
