Well, either open or shorted.  Come to think of it, a shorted 
transformer would cause a much higher current reading.  Make sense?

The Interstage audio Driver transformer, I believe, is the same in the 
Ranger and the Viking II.
Neither of 'em are much bigger'n a walnut (so it seems)

The sliding tap resistor is what sets the screen voltage.
Be very careful when sliding that tap... best to remove all stress from 
the 'slider' and don't slide it at all, rather open it up, place it 
where you want it, then re-secure it and measure.
