Mac SE screen

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.
