Default Re: CRT is brighter to one side [Hitachi CTP213]

There is not enough context in that image for me to know what A1 means, I suspect there is a physical PCB layout diagram associated with it, with X-Y co-ordinates.

What we mean by A1 however, is the CRT first anode.
I don't blame you for misunderstanding the jargon which must be new to you.
