Hi Jeremy,

I've just tried that little bifilar experiment as shown in the link but I get the exact same field strenght on both coils, driving at the same voltage and current.
Have you tried it? I also did a quick test on the Bedini SS, I had two power strands on one transistor, so I tried connecting the top (end) of one strand to the bottom of the other one, basically if they were parallel in the beginning now they were in series. I got a much higher voltage but the freq was way lower. But the charging rate was the same for both the setups.
I think what Aaron did can't be compared to the bifilar in your example as he has his load in between the two coils, that's probably why he had success. Before they were cancelling, now with one side inverted they add up. Correct me if I'm wrong Aaron.

best regards

Mario
