Thanks, Arran.The resistances on either side of the high voltage center tap were 169/151 ohms but, as noted, the voltages were identical.  The transformer was stone cold after 10 or 15 minutes of operation.

I spent some time preparing questions about the apparently open coil before I pulled the antenna transformer, but I decided to try to work it out myself.  And I did.  

With the transformer on the bench I still couldn’t physically identify the offending coil until I had some photos.  Then it was a matter of excavating wax to follow the wires (I‘m sure you‘ve all been there).

When I found the coil, it appeared to be intact before removing the wax.  It’s puzzling how the wire could break at this point--there was no oxidation and the wax appeared to be unmolested.

But it was broke, and I did fix it.  

Here’s my lesson of the week:  The transformer covers are riveted to the chassis.  Two days ago I cut the rivets to remove the cover so I could remove the transformer.  Just a few minutes ago I realized that I didn’t need to remove the covers at all--I could have pulled the transformer through the chassis instead.  Duh!
