Hi Mike, thanks for that info. Is the set in your avatar that color Zenith you mention? Could you post a larger photo of it please? Can't recall where, but I've seen a photo of some sort of public display with a very early color Zenith tube and chassis. It was declared to be experimental but was being shown to illustrate how technically proficient the company was. The sad irony is that they also led the development of the new digital standard but once Gold Star took over that seems to all have gone out the window.
