Flyback Transformer assistance requested
I am following the struct on using the single transistor driver. Specifically a 2n3055 from radio shack. Lets pretend i wouldn't waste your time if i didn't triple quadruple check the wiring first. using 24v dc power supply schematic and page i based my driver on.
i am not getting the high pitched noise from the flyback. i have 5w 220 resistor and a 5w 27 resistor . my resistance ratio is important. correct? since there is a voltage divider there. i know its vague but can someone give me some direction to work out my problems
