to _measure_ turns ratio you must unwind both pri and sec, and
even in that case the turns ratio can be integer only % )
Yes, but unwinding my tranny isn't going to happen. For myself, the turns ratio is input over output under load. I really don't care on the "actual" turns, only how the voltages and currents react (which is the whole point of turns ratio required calculations).

I am considering your coupling method for a comparison. With your method, a second high voltage supply is required (which is why I selected the other method). I could use my pole pig tranny to drive the NST Secondary and use my HV divider to ensure rated voltage at the secondary. Yes, this will be easy to do. I'll report back.

Take care,
Bart
