Default Dumont 1062 scope

wrote:

I recently picked up a Dumont scope type 2559a serial # 1252
Looks really cool and the thing weighs like 100 lbs.
Anyway I was playing with it over the holidays and it seems to be reading
vertically on the screen instead of horizontally like a normal scope.
Anyone ever heard of or seen that before? Any ideas?

Possibly somebody swapped the wires on the deflection plates. Usually there
are 4 wires poking out through holes in the CRT magnetic shield, with wires
to the deflection amps. You could try swapping the pairs of wires.
