** Assuming the transformers are the same size and do the same job, the
one with the 4000 ohm primary is stuffed.


I measured the turns ratio using a signal generator at 1khz and got 45,6
and 46,0


** Do not use a comma for the decimal point - it is way too confusing.


Wouldn't it be possible to have an original 4000ohm shorted to 900ohm too?


** No.

The ratio between rated primary Z and winding resistance is never less than
5:1 and is typically 10:1 or more.
