14LM1N
Indicator cathode-ray tube
Description
14LM1N is an indicator cathode-ray tube for visual registration of electrical processes in general-purpose radio equipment. It converts an electrical signal into a visible image on a phosphor screen and serves as the display element inside compatible equipment.

14LM1N function
The tube operates with heater, acceleration, focusing and beam-deflection circuits. These circuits determine image brightness, position and shape. Connection and permitted operating modes must follow the documentation for the instrument in which the CRT is installed.
14LM1N uses electrostatic beam focusing and magnetic deflection. Its 100 × 60 mm working screen has yellow-green phosphor with at least three seconds of persistence, making the trace easier to observe after excitation.
Identification and selection
The complete 14LM1N designation remains the primary identifier. Screen shape and dimensions, focusing and deflection methods, heater data, anode voltages, lead arrangement and envelope dimensions must also match. A visually similar tube with another designation is not an approved substitute without documentary confirmation.
Installation and handling
Protect the glass envelope from impact, point loading and sudden temperature change. Inspect the screen, neck, leads and sealed joints before installation. Clean the glass without pressure and without damaging the marking. High-voltage circuits must be tested only under the procedure specified for the host equipment.
Ordering 14LM1N
Please state the designation, equipment model and required quantity. The minimum order is 5 pieces. A marking photograph or manual reference helps confirm the execution. Related items are listed under Cathode-Ray Tubes; general principles are described in the Cathode-ray tube reference. Availability, condition and documents are confirmed with the supply offer.
