Checked all the transformers for resistance, and they're all fine.
Did a partial recap. Restuffed and replaced 17 out of 27 tubulars. They are the new looking caps at the right of the picture. I replaced them exactly as before, duplicating the factory positions.
On a lark, I plugged it into the variac and brought the a.c. up slowly. At 100 volts I tested the second anode and it read 7kV.
That's good enough for tonight.
