Whups, that's "current equals Power / Voltage".

100W / 9.05V = about 11A. To pull 11A out of a 9V source, we need a load impedance of 9/11, or about .82 ohms. The impedance ratio ( for one side of the center tap ) is 50/.82, or 61. The turns ratio is square root of 61. Let's call it 64 for a turns ratio of 8. ...but this is only one half of the primary. So  final answer  turns ratio of 4. I think.  Jerry
