That suggests to me that what we call the 'EHT' over here -- the 12kV-15kV
on the final anode of the CRT -- is low and is sagging under load. Low EHT
will cause a dim picture, it will also cause the electron beam to be
less 'stiff'
(as the electrons are not moving as fast) so the deflection coils have a greater
effect and the picture is larger.

Possibly more capacitor trouble in the flyback area.
