I have been experimenting with the relative setting of the G2 grids. The attached photo is with a low-brightness grey G2 setup (didn't upload for some reason; musta been too big. Substituted an ad c.u.). It is fairly decent and still viewable in the morning light. When a brighter grey is obtained with a relatively greater G2 setup, the resulting picture will lack adequate red phosphor output, an effect that is particularly noticeable where green is an element of the color being reproduced (as in that odd hue in the background of the GMA-set).
A low G2 grey setup provides greater G1 (control grid) response; a high G2 (brighter grey) setup delivers a brighter picture. With the greater G2 setup, I was able to watch the set during a bright sunny day with just the blinds closed.
So far, I haven’t been able to have it both ways.
Next step is to backup farther and readjust the red purity, which has deteriorated since set up weeks ago, as discovered last weekend during G2 adjustments. This will be at least part of the solution.
