Specialized - Cathode Ray ·CathodeRay
Sixty-three-centimeter three-gun shadow-mask color television CRT with a three-color phosphor-dot screen. Its direct-view construction combines separate color beams through the mask to form a full-color receiver image.
63 cm three-gun shadow-mask colour television CRT with three-colour phosphor-dot screen.
All-glass CRT 12-contact
General specifications
Properties common to every published source and operating point.
Electrical assignments shared by every tube using this base designation.
No verified pinout is recorded for this base designation.
