Cathode is another. Then you have at least two electrodes to accelerate and focus the
electron beam. So depending on the structure of the electron gun system, you?d see 5 or 6
pins in use.

Incidentally, how many connections are there to the base of the CRT?
Remember if it's electrostatic, there will have to be 4 for the
deflection
plates
[1] Two for the heater in all CRTs. So if you
only have
6 or 7 connecitons , it's not going to be electrostatic, there aren't
enough pins
for the electrodes.
There are a total of six pins used on the CRT.
Clearly, two of these are for the heater supply. If it's magnetic
deflection, via the coils on the neck of the CRT, what would the other
four connections at the end of the CRT be?
