This has nothing to do with the problem we have been chasing, but Istarts with power supplies, then goes on to the CRT.
The CRT adjustment procedure will have a bunch of interacting adjustments -
it could be e.g. that the geometry pot has drifted. It may also help for a
scope that's been stored for a long time, to let the CRT "bake" for a few
hours to days with a low-intensity beam. See e.g. <
.Also, you shouldn't expect the 2465 to match your 454A for trace clarity or
dot size, as the 2465's CRT has an expansion mesh.
I've only been through the CRT adjustment for my 2467, which has a very
different CRT, and it's been a couple of years, so I can't help much there.
