ok, after messing around with the pots a little that's not actually too awful of a geometry. I kinda wish the contrast was a little better though.

@slyka Have you got any control over the EHT? That let you might improve the contrast.

@slyka i had not yet one of these for a reverse engineering (only traditional straight CRT), wondering how the trapeziodal geometry corrention is happening Modulation of horizontal deflection amplitude? complicated asymetric vertical deflection coils (like german prewar TV)? or a modulation voltage to a electrostatic deflection electrode (might also fix the focus)
