Default EAR 509 OPT Impedances

What are the likely impedances of the anode/cathode and the feedback windings in the EAR 509 output transformer, and how would one calculate them?

Alternatively, has anyone measured the impedances of an actual EAR 509 output transformer?

I believe the anode and the cathode windings have equal numbers of turns.
