15LO1I

15LO1I 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.

The tube has a rectangular green screen with a parallax-free scale, one post-acceleration stage, a correction anode for astigmatism and electrostatic deflection. The envelope is glass and baseless, with additional leads on the bulb and neck.

Identification and selection

The complete 15LO1I 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 15LO1I

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.
