Thanks, Sam. I finally got to snap a few pictures. It's very similar....

   

Only the RCA jack port is in the audio transformer at the bottom of the cabinet, this being the transformer for the phono arm. You can see it next to the chassis in the photo, sitting inside the cabinet loose. The two terminals are marked "Red" & "Black" corresponding to the leads from the BOL tone arm. The 3 prong port next to the terminal must be for an external antenna attachment.

   

There are three wires connected to the two terminals. One goes to the BOL light focus adjustment on the back side of the chassis, one goes to a terminal strip near the XXD tube, and the other goes to the light reproducer coil (#19 on the schematic). The problem I'm having is these connections to the terminal are not shown on the schematic. At least not that I could find. I ordered a set of schematics from Chuck and he had the exact same pages I already had... taken from the 1941 Philco "Yearbook", which I also have an original copy of. I will have to do some more wire tracing from these points and see where they end up. And wire replacement...
