Hi, One of the projects in this website cocerns a circuit which uses a TV flyback to generate high voltages for experiments on sparks and so on. The circuit diagram shows just 2 windings on the LOPT; primary and secondary ( EHT winding ), but, in reality, a real TV flyback has several windings designed to generate various voltages for the TV set. Theres no simple way that I know of to decide which of these windings is which ( resistance measurements are not much help - they could easily mislead ) So, how does one find the original primary? How did the author do it on his? Regards Poriet PS Please email any answers to me, or I'll probably never see them.Ta.
