The TV CRT project thread g0t me thinking about old TV CRTs and scopes. And I may have learned this eons ago but I have forgotten. Why did not TV CRTs use electrostatic deflection / deflection plates as opposed to magnetic deflection with a yoke? Was it the cost of producing such a tube?
Never had to do it on a scope but did scopes need to have the beam aligned periodically, similar to convergence adjustment in a TV? In fact, I don't ever remember doing any kind of beam alignment on a black and white TV. I am guessing with only one gun, the alignment was not as critical as color with 3 guns. Was it the same with scopes?
