It's interesting that he shows different dc resistance for primary and

The winding are separate, one inside the other so it has shorter turns and a lower resistance, the other is outside and has longer turns so it has a higher resistance.
Okay, that makes sense...

This data can be used as your friend, feed your output signal to the higher resistance and take your signal from the lower, this way the lower resistance is shielded to some degree by the outer winding and will >probably< pick up less stray noise.
I wouldn't have thought to do that, either. I'll have to check the ones I salvaged, and see what they measure.
