[ARC5] Info sought about output transformer in BC-221-AK

[Leslie Smith]

The subject line is the point of this posting.

More info:  (1) This transformer is shown as item 17 in the circuit diagram for the "AK".
The manual describes this as "output transformer".  
I find no other information in the BC-221 manual.
In particular I wish to know the impedance of the primary & secondary windings.

Thanks to all,
