Anyone have any ideas as to why this radio's rectifier tube is the only tube working in this radio?

I checked the 6.3V filiment winding in the transformer and its not open or shorted or anything and all of the filiment lines have continuity (no open filiment wires between the 6.3V filiment transformer and the end of the 6.3V filiment string) and all of the tubes are good (no open filiments, or shorted tubes.)

Also the pilot lamp isn't glowing either, and I double checked the bulb with the bulb checker on my Knight tube checker and the bulb glows as it should, and the winding in the transformer that the pilot light is powered from has continuity (isn't opened or shorted.)

Any ideas as to what could be causing this radio to not function?
