Thanks for the info and suggestions!
Below are three more images - clearer pictures of the front and back of the transformer and a picture of the circuitry directly below the transformer.
I tested continuity on the primary and various secondaries and it was as expected based on the labeling - had continuity between the 110V and 0V on the primary, and in the expected places on the secondaries both front and back.
Some questions...
To test the voltages, I need some sort of load correct? Would something like a 50 watt incandescent bulb do the trick?
I assume the smaller tubes are rectifiers? Do you know what designation would fit the bill?

- You don't need a load on the transformer, and the smaller tubes are signal tubes nt - Ralph 08:21:32 09/14/20 (7)
