Cathode-Ray Tubes

Cathode-ray tubes are indexed here by exact type, screen execution and display function. The section includes indicator, oscilloscope, storage and projection CRTs for radar displays, measuring instruments and electronic information systems. Similar screen size or envelope shape does not demonstrate interchangeability.

Indicator, oscilloscope, storage and projection CRTs

The catalogue includes LM indicator tubes, LO oscilloscope tubes, LK projection and picture tubes, and LN storage types. Each execution may have a different screen shape, phosphor colour, persistence, focusing system, deflection method and electrical circuit. The complete Latin transliteration and original Cyrillic marking are retained for search.

Screen, beam control and electrical data guide selection

Compare the full marking with the host-equipment documentation. Confirm screen dimensions, phosphor, persistence, heater data, anode voltage, electrostatic or magnetic focusing, deflection, lead arrangement and envelope dimensions.

• record the complete CRT designation;
• identify the screen colour and persistence;
• check focusing and deflection methods;
• attach marking and connector photographs;
• state equipment model, quantity and documents.
