Is this 16 or 19 inch?
 

This might be a potential cabinet for the color prototype set, but I need to know what size the CRT is. Looks too big from what I can see, I need one that uses a metal 16" tube. The seller says this one is a full 24" deep, and that's a good thing because the chassis needs space.

That is a 16gp4 in that one almost certain of it. It's too large to be a 12, and the only round 16" RCA sets that I have seen are 16GP4 tubes.

here is a link to my TC166 with the 16GP4

The RCA 8TC721 uses a 16AP4 but I have never seen a 16AP4 in a console like this.
