CV1518 CRT
 |
This CRT measures 380x110 (screen) overall and has a 12 pin B12B base. |
This is an electrostatic, split beam CRT. The Y plates are suitable for asymmetrical deflection only; the X plates are suitable for asymmetrical or symmetrical deflection.
It has a BB3 (Blue/Blue/very short persistence) or GG3 (Green/Green/very short persistence) screen. The prototype is VCR518. This CRT is a replacement for the CV963
