    what would be the best way to wind a homemade transformer for this circuit here:

    it calls for a 1.2:1 ratio with center taps on each side. i have several toroidal cores as well as ferrite rods. im a little lost because there are so many variables: wire guage, inductance, core Al,dc resistance, loading, etc. there are a lot of different ways to come up with 1.2:1. what would be the best and easiest route in your opinion? thanks in advace!
