CV2431 CRT
 |
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.
