Without looking at any of your data I'm thinking that somebody monkeyed with the IF transformers before you got the radio and it's not on the prescribed IF frequency. First you have to know what that frequency is, should be in the repair data somewhere. It "might" be 455 kc but early sets varied.

It would be easy enough to figure out with a signal generator set to the IF frequency but if you don't have that, I'm thinking you could take the IF signal from the output of the good radio and feed it to the input of the IF of the problem set. This might be done with minimal coupling, like wrapping a wire around the IF tube of the good set and running over and putting the wire near the input IF transformer wiring of the problem set. Yank the oscillator tube from the problem set. If the problem set is right on IF, the signal should feed through. If not, adjusting the IF transformers on the problem set should pick it up. Mark IF position screws and write down how many turns so you can put it back if no dice.
