You could look in the manual at the schematics and see if they are 
powered by the same transformer secondary as the 3CX800A7 filaments. I 
think that is 6.3 V which would make them plain old #47 lamps. Don't 
take my word for it though, confirm before you buy, and when you buy, 
order enough to get the quantity discount from Mouser, Digikey or other. 
You could look at the number on the burnt out lamp. Some just have a two 
digit number, some have a prefix such as CMI (Chicago Miniature). Once 
upon a time this pilot lamp bulbs used a color code. The glass bead the 
holds the wires in position to suspend the filament coulb be various 
colors, which represented the bulb type. Old Amateur Radio Handbooks had 
that data in the back along with the tube and transistor data.
