I will do that tomorrow. People have worked on this chassis in the past but it looks like it was limited to cutting off the tube shield bases to put in metal tubes; replacing some resistors and tacking on new capacitors in parallel with the old bakelite capacitors. Pretty sloppy work.
At some point I will remove everything going to the input transformer and remove it to check it out more throroughly.
I have seen other transformers that developed spots of corrosion leading to high ohm readings. I've jolted them with about 400-500V DC from my capacitor tester and have brought some of them (and some field coils) back down to a reasonable reading. If they are completely open it doesn't work.
