Spot size and g1 drive...
Just one curiosity, about this subject (a "side topic" related), if one knows about it:
Some B&W sets have g1 driven and cathode grounded for AC. Some color ones also have, for color difference.
This variable g1 not results in a variable beam size/spot size for these sets? Or signal is too low to produce an appreciable difference?
This subject of this thread makes me wonder about it.
(The TV here have only k driven, so will not have this issue).
