Bea was most helpful. She provided a few things to check and one was the coupling capacitor for that output tube. Bingo! My capacitance meter determined that it had failed.

She is sending me a replacement along with the suggestion that at some I consider updating all of them with the ones used in the current 450s.

Should be up and running shortly!
