[AMRadio] Questions on Johnson Ranger II

[kc9cdt at aol.com]

Geoff,
Are you talking about the MOD XFMR or the audio XFMR?

I will cut off one end  of the resistor, then meter it to see if it's 
OK..

73,
Lee

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.
