Replace or repair power transformer?
#3

The transformer might still be good. I have seen some in worse shape that were still good. It might have just gotten warm. As Arran suggested ohm out the transformer and make sure it still has continuity. If it tests good then you can power the set up with all the tubes out and see if it gets warm with no load. If it does it's pretty much junk. If it stays cool I would proceed to restore the radio.

You can pull the bells off the transformer but there is two tabs that fold over on the bottom. You will need to take the transformer loose from the chassis and bend these tabs straight for the bells to come off. You can see the tabs in the picture from my Philco 71.
