This type of crt has a eight pin base like the model A28-11W;

Questo tipo di crt ha un connettore a 8 pin così come il modello A28-11W

I have loaded the socket wiring for the tube A28-12W and 280CB4.

It is an 8-contact socket.
Please correct the data for both tubes.

Regards WB.

Yes, it is an 8-holes socket,
but only seven contacts are forseen...

Also called JEDEC B7-208

Kind regards
