    What is the turn ratio of this component (1-2:2-3)?
    Is it 8.7? - 1/76 = (1/n)^2

    That will be a reasonably close approximation. Note that the inductances have a 10% tolerance.

    The resistance ratios are 1:28 roughly....

    I would expect the inductance ratios to be the better estimate. The resistances depend on the wire diameter used whereas the inductance doesn't.

    Well i would input a low voltage ac into pins 2-3 and measure it on 1-2 to see the difference in ratios.
