[G.B.]

Wow, we do have some vintage color tv adjusters for R.G.B. gray scale adjusting. we also would add a bit more red in fringe area ? On new sets this would be the warm setting. We would always notice more red in a local city broadcasting & less in the fringe area. This was what I was told by a man of that era when I first got started. Don't know if this was a delay in the color decoder or what. They just always said to do it.....
