8591A CRT shrinking picture size

I have an old 8591A that is working nicely for several years but the CRT is showing something weird lately.
When I connect the unit the image is full size and clear, but some minutes after, the image shrinks down, in both horizontal an vertical size (while keeping focus).

I am not an expert on CRTs so I cannot tell this is an awful problem or perhaps one easy to fix.

Does anyone know what may be happening here? Any point to check? Please dont tell me I need to replace the CRT! :-(
