Do you have a tube tester?
There can be many reasons. Tubes - one of them. It is unlikely your transformer. This is not a typical way they quit (possible but rare).
Do what John suggested. Then test the tubes. Especially you need to test 6X5.
One thing I would suggest myself: (after you do what John said) as you said, the radio does not smoke and the transformer is cool. If this is the case you could try to measure the B+ as it is. Measure it across the 8uF (I think it is 20A cap, the one after the field coil), between its chassis and the positive terminal.

People who do not drink, do not smoke, do not eat red meat will one day feel really stupid lying there and dying from nothing.
