    The hole in the center of the torroid is open. You can just take some magnet wire and add all of the auxiliary windings that you cant into the window.

    If you make a test winding of, say, 10 or 20 turns, you can calculate volts per turn and calculate the number of turns needed for each aux. winding.

    I asked for the specifications so I could determine whether I could make one. Unfortunately, I don't have cores that are suitable for such a large transformer such a low frequency.
