RE: So this happened . . . any thoughts on the cause?

Schematic shows a 4A slow blow fuse in the filament circuit for the preamp tubes.
That's internal, and probably blown.
I've also come across the rectifiers failing, and due to the heat generated bad solder joints on the rectifiers. If it isn't the fuse, then it should go to get serviced.
