Well, not only was the screen dead but the analogue board too. The part #s
for the screens in the Plus, SE and Classic were the same, except the
classic was a slightly different sub-variant (E instead of D). I installed
the Classic CRT and got nothing, nix, nada, so I figured if the Classic was
mostly dead it was OK to assume the screen was too. I only thought about the
analogue board when I'd installed the Plus screen, so I swapped that too and
hey presto - working SE. I then put the Classic screen in the Plus and that
works too, so there's now a completely dead Classic available (well, the
mobo might be OK) as well as the bones of an SE! There's no point in keeping
the bust CRTs since they're beyond repair.

I'll do it then, and compare the numbers and boards etc, and check
apple-history to make sure the resolutions were the same,
which I think they
were.
The resolution shouldn't matter for a monochrome CRT (there are no
phosphor dots/stripes on such a screen). The resolution is really
determined by the driver electronics, although the yoke is
likely to be
different as well (different scan rates -> different yoke
inducatance, etc)

The good old british postal service

CRT. They
Ah... That explains it :-(
