Can anyone give me a ballpark on the DCR of this particular

** Assuming the tranny has a regulation factor of 10%, that equates to 6 volts copper loss on the primary under full load.

Rated load is 36 VA plus a little for Imag gives 40VA.

So the primary current with resistive load is 0.33amps rms.

Makes the primary R = 18ohms.

A similar, 240V tranny would have four times the primary R.
