Only thing I remember (1962) was that the set was screwed up a lot and wouldnt last long. Sometimes when I came home to watch it the thing just wouldnt turn on.
I know very little about the inner workings but I certainly remember taking tubes in a grocery bag to the grocery store to use their tube tester and check tubes. I also remember how good the picture was on some of those old round tube TVs. The last one I had (1978) I let play for 4 years without turning it off. Every time you turned it on it would take longer and longer to get bright enough to watch so we just left it on, turned the sound down at night. then one day the power supply melted and smoke was every where. I remember the insulation on the wires was so hard and brittle that you couldnt move a wire without shattering the insulation. This was before we let it play so long. I was young and foolish and never thought about consequences. That TV was a RCA, dont remember the model but its picture even by todays standards was spectacular. I certainly understand the appeal of these early birds.
