Yours is the second 46-420 I've seen posted about that had a miniature output tube (50B5?) whereas the nostalgia air schematic shows a 50L6 octal.

Retro-Tronics has a back for this model. I don't see any screw holes. Maybe friction keeps it in place?

Yep, 50B5.

The back is held on by clips that fasten to the back and held to the case by friction.
