anyone got experience using deguassing wands, such as the one pictured, on CRTs that don't have built-in degaussing coils? do they work? any sage advice from arcade & retro tech enthusiasts?
the little 4-inch CRTs we used in the infopoints at EMF Camp have some nonlinear warping that isn't corrected by tweaking the deflection oscillator amplitude/phase adjustment pots, and also isn't consistent with the tube curvature, so I'm suspicious of static magnetic fields.
