I had a huge collection of old TV sets (all trash-day finds, of course) in the basement of my former home back in the early 1970s; gee, I wish I would have taken a picture or two of it (them) so I could scan it into my computer and show them off now, thirty-odd years later. I had just about every American make of television down there except Magnavox. I'd list them here, but I can't remember them all anymore.
My old neighborhood, near Cleveland, was also Zenith land, maybe not so much as drh4683's hometown, but a lot of my neighbors in my former hometown had Zenith consoles, portables, roundies . . . you name it, in the 50s and 60s. (I picked up one Zenith Space Command "300" portable--without the remote--in the late '70s and used it in my bedroom as my main set; it lasted only about a year before the horizontal-output tube went gassy and overbiased the RF amp in the tuner, not to mention the IF strip and AGC, so badly as to practically wipe out the picture.) I'm not saying we had more Zeniths than Doug's hometown had, but there were a lot of them out by the curb on trash day, every week, as the old sets developed serious problems or defective CRTs and were replaced by newer, and in some cases bigger, color sets. I once picked up a 23-inch Zenith b&w console which someone had filched all but one tube out of; I retubed that set (it still had a very strong 23ANP4 CRT, which produced a beautiful picture) and it worked, for three whole years. I even patched an FM tuner into the audio system to make a cheap-and-dirty mono hi-fi system (that set had a wonderful and great-sounding audio channel, with a 6BN6 quad detector and 6BQ5 output stage, not to mention a 6x9 oval speaker in the cabinet directly below the CRT). Then my dad remarried and we moved, which meant getting rid of all but two of those nice old TVs I had in our basement
including my pride and joy 23-inch Zenith, which I had so lovingly rebuilt from the ground up over the course of a year. There were so many old TVs being put out for the trash each week before we moved that I swear, my neighbors must have thought we were running a TV repair shop out of the basement!
Good luck, guys, and very kind regards, as always.
