For this problem I would check C94, the cathode-cap' on B18p

The narrow raster could be caused by a number of severe problems with the line-output circuit including a shot B14/PL36.
If you're in luck it COULD also be caused by the linefrequency oscillator running wild. A good candidate for a culprit here would be C176, next to the lineoscillator coil S30.

Good luck and be sure to report back with pictures of the 'LOTS' at work
