Usually there is a label on the bell of the CRT usually on the side usually near the screen that will have the ID number on it...It may be hidden under the shield. Is there a tube layout for the TV section inside the set? If so it should list the CRT (probably a 25XP22 or something similar)....Honestly the guns in large screen delta-gun tubes (anything bigger than 20") are pretty much all the same and should use the same test settings.
