Refresh rate? flicker appears more noticable on the green.

G'day,

When looking directly at the tubes with a static white background at very low contrast and brightness (so I don't go blind!), the red raster appears flicker free, the blue raster has a slight flicker and the green has slightly more flicker (than the blue). The flicker is not really noticable on the screen, and it looks like perhaps a refresh rate flicker. Should the blue and green be (relatively) flicker free like the red? I'm thinking that this may reduce the sharpness of on screen images.

Any thoughts?

I notice that as well.
Kind of weard as green has the slowest decay if them all and creates a clearly visible rbe like effect. Or maybe it's drawn slightly after the other two and has shorter "hight brightness" persistence.
It glows forever at low brightness though.

I might have to scope it and see what's happening.
