It's all looking good so far. The o/c output transformer may be why the radio went out of use and there may not be any other actual faults, just age deterioration.

Examine the transformer carefully. They sometimes go o/c close to the solder tags and can be repaired quite easily.

If you need to replace, don't be overly concerned about the turns ratio as this is a lot less critical than is often assumed. There will be an ideal ratio depending on the ideal anode load impedence and the speaker impedence, but you can be as much as -50+100% out and still get reasonable performance. The only effect will be a reduction in maximum volume which may not even be audible.
