The metal cone makes it impractical to mount an AXP into and FBP set but the reverse is possible, though mounting hardware modifications are often needed.

The tradeoff of the rare earth phosphors is decreased color gamut to get increased brightness. The 15GP22, and to an extent the 21AXP22 use the phosphors that the NTSC color system was designed for, but later tubes do not.

The CYP was basically an FBP with 2 anode connections.
