Raster Rotation

[crtfool]

Are you sure that this is a new problem? Maybe you just never really noticed it before. It is unlikely that a monitor this old with a cemented yoke could just shift the raster rotation. The slight pincushioning may be adjustable, but I would not attempt it.

I am a bit of a fanatic when it comes to geometry issues, but your monitor looks great to me - the crosshatch is nearly perfect, as far as I am concerned - this would not bother me at all.
