Hello, I am new to Tesla Coils and I am in process of designing one using a flyback transformer. I am curious whether I can have a duel resonance between the primary and secondary since the transformer is already wound and I have no control over the inductance. Also is it possible for it to look like the 'classical' tesla coil with a slender middle that goes to a toroid top load? Most of the designs that I have seen using a flyback only have small arcs from a pointed electrode.
