My great-aunts had a Capehart 16" round-tube console TV in the 1950s. When they got a new Motorola portable b&w set in the early sixties, they gave me the Capehart, which I had in my bedroom for several years when I was a kid. The set worked well, IIRC, even in the near-fringe TV reception area I lived in at the time, but something has always puzzled me about its power cord. I remember it was about ten feet(!) long and had a circuit in a small metal box right in the middle of it (the circuit in the box was in series with the cord); the box ordinarily sat in the base of the console cabinet. I had almost forgotten about that until I spotted this Capehart TV thread; now I'm starting to wonder again, almost 40 years later. An interference filter, perhaps?
I kept the cabinet for years after the TV went West and made a storage cabinet of it--this was several years before I ever got interested in collecting old TVs and
long before there was any such thing as the Internet or AK. Had I gotten this set later on, say in the late sixties or early 1970s (before I moved the first time), I no doubt would have tried to repair the Capehart chassis.
