Hi Zagnut,
will this type of transformer work good with the simple oscillator circuit the RCM ignition uses? or does it need something more complicated like the 3W ignition that has a pair of transistors and a bunch of other crap?
any way to calculate the frequency according to the component values used?
Yes! It works great.Better than a Torroid in my opinion.I added to the RCM version and what I ended up with is Better.The transformer has 250turns on the sec,8 turns on the FeedBack,and 16 Turns on the Primary.The output of the SEC one leg goes to ground and the other goes through a Voltage doubler.I get 400 volts.Idon't know how to calculate the Freq.But I play with the values of the Resistors until I get the Right voltage.
