The procedure is the same for AA5 or anything else, just the scope of the project is a tad bigger.
Same thing: recap first.
Also: 1941 radio might have the rubber insulation on the wires cracking: if you see any of that, replace the affected wiring. In my case, 41-280, all wires were fine.
Now that you have a transformer, without any tubes measure the output and confirm the transformer is good before you commit, unless you are willing to proceed even if it is bad.
Without the rectifier tube but with the rest of them in measure the voltages across the filaments, confirm they are ok.
Then proceed as usual: after recap, rectifier tube in, measure voltages etc.
