Does anyone know if a 23VATP22 or 23VCRP22 can be substituted for a 25AP22? The screen size should be the same but I'm not sure about the "ATP" and "CRP". Also, what's the difference between a 25AP22A and a plain 25AP22?

they will all work electronically and show a picture.back in the day we did so many swaps,it was incredible.used to keep a record of which tube went where,the effects,etc.i just used a 23vatp22 in my frankenset :ctc16xl modified for a 25ap22.it worked out very well and i am pleased with the result.
my friend has a ctc 25 that he used a zenith 23v.cant really tell how it came out as he has a nasty video problem.his set also used the 25ap22.

23VATP22 yes will sub 25AP22
23VCRP22 will not sub.
