Thanks both,

I don't think it's mechanical - I'm not even touching the set when it suddenly fixes itself although I suppose there could be a change brought about by the CRT heating up (or could it be the CRT gun itself).

DC into the scan coils is worth considering - I should be able to see that on a scope. I've only looked at the line output anode and that doesn't seem to change.
