CV2431 CRT

Size This CRT measures 167x68mm overall and has a 12 pin B12A base

 

The screen of this CRT gives a green fluorescence and a green afterglow of medium persistence. It has a transparent conductive coating between the glass and the phosphor connected to A3 - this prevents the raster being distorted when A3 is at a high voltage and the screen is touched.

Heater voltage 6.3V
Heater current 300mA
Max final anode (a3) voltage 800V
Min final anode voltage 400V
Max second anode (a2) voltage 200V
Max first anode voltage 800V
Max negative grid voltage -160V
Min x-plate sensitivity 110/Va3 mm/V
min y-plate sensitivity 175/Va3 mm/V
Max peak voltage between x-plates 750V
Max peak voltage between y-plates 450V
