I have an Admiral 30A1 with a 10 inch CRT. I also have Admiral documentation. Apparently the documentation isn’t great !! I can’t see any numbers on the CRT and I don’t want to disassemble anything to get to a number, if there is one. This TV comes with three different CRTs, 10 inch, 12 inch, and 16 inch. They refer to the CRT simply as V308 and I see no parts list. I suspect this is a 10BP4, but want verification.

Anyone know what tube this uses?

If it was a 10" then it should be a 10BP4. The only other commonly seen 10" tube was the 10FP4, which doesn't use an ion trap because it's aluminized. Other than that the two types are completely interchangeable. If your 10" tube has an ion trap it pretty much has to be a 10BP4.

It has the trap so it is a 10BP4. Thank you so much.

Just be aware that many tubes with ion traps have aluminised screens. Just as there are non-aluminised screen tubes that don't use ion traps (early UK Mazda CRTs come to mind).

How do you tell? Look for a "bent" gun, or a gun with some cylindrical parts cut at an angle.
