Here are two of my rectangular sets.
The Zenith(top left) uses the 23V, and the Airline(bottom left) uses the 25GP
The sets below I reciently bought from Nick.
The larger console is my Admiral(from another thread), and uses a 25AP22 according to it's tube chart; I cant see the label through the shield(it blocks my X-ray vision
).
The smaller is a Zentih, and has an RCA 22JP22, but it originally had a 22QP22 according to the tube chart. see photo below.
