Specialized - Cathode Ray ·CathodeRay
Direct-view rectangular television monitor tube with a metal-backed white screen, designed for professional television monitoring rather than domestic receiver display.
Direct-view rectangular television monitor tube with metal-backed white screen.
Duodecal 7-contact CRT base
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.
1 physical section, each with unique specifications.
Section 1
No fixed ratings are recorded for this section.
CRT-specific electrical, optical, deflection, focusing, capacitance, and mechanical data are retained in TUBE_SECTION_PARAMETER because the locked promoted fields primarily target conventional electrode sections.
Source-dependent data
Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.
