Have you tried tapping the instrument (gently) to see if it's sensitive to vibration. I think it would have to be very touchy to get these results from the mere vibration of turning a knob but it just seems so general that it's possible. While it could be the CRT it doesn't look like it to me so don't slash your wrists just yet. I've never worked on one of these but is it possible to measure the deflection voltage going to the tube. You should be able to see it jumping all over the place in sympathy with the trace movement.
At least you've won weird fault of the month award.
PS can someone advise if this model overheats if operated with the covers off and needs a desk fan blowing into it while working on it?
