Specialized - Cathode Ray ·CathodeRay
Fourteen-centimeter rectangular domed-mesh oscilloscope CRT with internal graticule, designed for precision waveform presentation with high-brightness electrostatic beam control.
14 cm rectangular domed-mesh CRT with internal graticule. The supplied Philips sheet was read for heater, accelerator, focusing, deflection, capacitance, limiting-value and screen data.
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.
Cathode-ray tube section. Accelerator, deflection, focus and screen-specific electrical data are retained as parameters rather than forced into unrelated plate/screen fields.
Source-dependent data
Each block preserves the test conditions and published values from one reference. Values from different sources are intentionally kept separate.
