I really need to exhume a Zenith porthole I have here and restore it. I got it off a guy for $25 about 20 years ago. He had cleaned out the basement of the old Molleur Brothers store in Pittsfield here, so that a nonprofit organization he was with could conduct their affairs in the space. Molleur dealt in Zenith from nearly day one. The 12LP4 put up a bright raster, and the old set did work fairly well, with a good sharp picture. But it needs to be recapped at this point. Gotta dig this set out this coming winter and do what needs doing. This thread--along with others--may inspire me....
