I see I'm not the first to think of that! I'm testing a tube focus system in my
home-brew vector monitor, although slow focus slew rate
is one of the reasons it may have been scrapped earlier...
Also, picture tubes don't like wildly varying voltage there, my test tube can sing
at the right rate...
It's a shame that no HV transistors are made to take over about 2000 volts...
