I think it is something to do with the composition of the wedges, probably a similar kind of thing to those rubber belts that turn to goo over a number of years. Some sets had grey wedges and I never saw this problem where they were used.

If you really value the monitor you could probably use a CRT assembly from a 14 inch portable TV, if you can find a good one. I know I did this with the earlier CPC monitors.
I've found someone round the corner from me with a grundig 14" tv so might go get that and see if I can use the tube off that.
