Re: CRT is brighter to one side [Hitachi CTP213]
I might be wrong but that doesn't look like an EHT tripler to me, it looks like the focus assembly, according to a schematic I'm looking at the EHT rect. is part of the LOPTX.
The RGB output HT decoupler(s) appear to be on the main power/deflection board
(2 x 3.3uF) and not on the CRT panel so far as I can make out.
