Not as pink as expected by a long shot. Turned out to be a dead spot at the wiper on the green drive control. Returned to normal when touched and after a couple of turns to excersise it, no problen at all. Touched up the purity. it looked like it changed slightly after the ride home the other day.
In setting up this set several times I have observed the static convergence magnets are at their extream ends of their range (some almost touching the glass, some barely still in the slider) to get proper center registration. Adjusting the purity even slightly causes a moderate interaction with that center convergence. Could the magnets be so weak that they are influenced by the purity rings or just a picky gun structure?
