Happy Victory at Adwa Day.
I need to make or have made a toroidal transformer with multiple turns to fit over a ~5" ~125mm conducting tube acting as a single turn through the middle. A ferrite core would be good, but finding the exact size would be difficult.
Tape wound Silicon Iron as used on mains toroids sounds like the easiest way to fabricate one, but is there any chance of it working at 40kHz max or am I wasting my time thinking about it?
Cheers
