More Than I Can Chew?

If a 5 pin socket probably an 807.  However, the 12 volt equivalent, the 1625, takes a 7 pin socket.  Also, probably not a 2E24.  That tube has "a quick heating filament" and almost certainly would not be used in such a transmitter.  It could be a 2E26 which is a smaller version of the 6146 and has a "normal" heater ("filament") or a 6146 if an octal socket and a plate cap.

Your tubes there are a rectifier and the 6C5 crystal oscillator. If you have a 5 pin socket  for the PA and a separate plate lead, it's most likely an 807 or 1625 - depending on the filament voltage. If it's an octal socket, with no plate clip, it may be a 6L6. If there is a plate clip, it could be a 6146 or 2E24.
