I got an old CRT analog oscilloscope recently and it's acting a little odd. When using the built-in calibration square wave, the right side of it seems compressed, as if the wave has a higher frequency on the right side of the screen. I've tried a different probe and that's not the problem. Any suggestions of what it could be?
Model?

Mostly a supply / input switch problem.
High voltages inside, take care.
Try and find service manual, or at least schematic.

X-axis deflection amps? Sawtooth generator circuit?
