50-922 Output Tube
#10

One wierd set you are working on.

Well pinout is same as 7B6 or 7C6 if you have specs for it, just need to set filament voltage to 12.6. A rewire to the octal world using the readily obtanable 12SQ7 is one workaround should you not be able to find suitable replacement. Also, if the triode section is working ala buzz when you touch the center terminal of the volume control with volume turned up all the way, you can bypass the diode sections with 1N34 diodes. Kind of hard to kill some of these old buggers though.
