12LO1I

12LO1I 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 combines crossed electrostatic lenses with a gridless deflection-amplification system. This arrangement provides high deflection sensitivity in a comparatively short 260 mm envelope.

Identification and selection

The complete 12LO1I 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 12LO1I

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.
