Phillips 25 Inch CRT

[Console User]

Looking for any information on the following:

I purchased a used 1999 Zenith Console Set Model B25A74R last year. I decided to take the back loose and look inside. I see it has the following CRT in it: A63AFW36X made by Phillips. I had a parts sheet for this particular set along. It shows in the parts list A63AGD01X. Can anyone tell me did Zenith also use the Phillips CRT in these late 90s-early 2000s sets or does this show that the CRT has been replaced in this Set? Also, how good of quality and lifespan did these two particular CRTs have? Thanks.

I had the 27 Inch Console Set Version of this particular Model, but unfortunately it literally fell apart when moving the set out.
