Well, I know what I've got a constant voltage transformer that gives a sine output.
The resonant secondary coil and capacitor that is connected to some electronic
circuitry, well, I don't know whether I can just forget that, ie just disconnect and
just have the capacitor in circuit but nothing else. I think constant voltage
transformers work okay with just the capacitor.
I don't suppose anyone knows of any applicable electronic circuitry that goes with
CVT's, and connects to the resonant secondary.
