No, it doesn't look right. I have the same scope (also NOS, maybe
from the same MOD source ?) and mine looks like the first image.
IIRC, the character generator has 2 sets of adjustments, some on
the board itself (position, hight , width etc) and more adjustments
on the V-output amp where the vector is summed (and possibly on
H-output as well). I bet the lead routes make a difference too . I
also have a 7603 with a similar looking defect (it resisted my
attempts to adjust it / fix it - but it's a spare so I didn't look too hard)
You will need the serial numbers as there are serveral different versions ...

Thanks for that, looks like the easiest way forward is to swap out the
board (se my wanted post for details). David partridge thinks I can
use any known good board in any 7633 scope and they should work, have
you ever had cause to swap early for late etcetera? My scope came from
a dealers in Somerset, I think they had three of them, certainly two
anyway. Apart from the character display it's been fine, and I wasn't
even aware it was not as it should be until I saw some photos of
similar scopes showing a display. I can live with it as it is, but
would like to sort it as it kind of bugs me now :) Thanks dc
