Well, it took me a while to process everything y'all said. Regarding my question about loading the transformer--I was, indeed, confusing it with something I read about not powering the radio without connecting the speaker.
I was concerned that wax under the transformer is a bad sign. I had unbolted the transformer a few days ago to find the part number, and there was a thick layer of wax underneath.
The good news is that I ran the thing up to 120VAC and got 382V on each side of the center tap. The data says 680V at the plates, so that's pretty close. My meter only reads up to 600V, so I checked the output voltages with 60VAC and 90VAC, and the results were in appropriate proportions.
Now I have to resolve an open coil in the antenna transformer. That should be the last obstacle to completing the restoration.
Thanks again,
Henry
