Before you can Calculate the Turns, You Need to know the "AL" Value of the Core that you intend to use.
The AL Value will determine the Inductance, Verses the Turns.

You also need to know What Currents each output is?

And Is your EI Core Big Enough to handle this Power?

Is this a Transformer you are RE-Winding?
Or is it New E/I Plates?
