I went back to revisit a long list of emails exchanges with the service technician that repaired my KV 7010U. He said thinking about it later, he should have measured for RF radiation, but did not. He said DC voltage is applied to the color selection grid and creates an "electronic lens" which focus's the electron beams to the correct color stripe without need for convergence. That is why there is two HV supplies. It's called "post acceleration and focus effect"
I don't much about repairing sets and would not want to touch anything for fear of screwing things up.
