Hello Jac,
the TV12B has two other faults to correct. As the attachment shows the vertical linearity could be better and the vision alignment needs attending to. Sound on vision and over emphasis of the vision HF component.

I'm considering replacing the MW22-14 CRT with the ion trap MW22-16. The original tube has evidence of ion burn and as this set has almost 7KV EHT available I'm certain there will be a worthwhile improvement in picture quality by fitting the later tube.
