My petroliana collection is mostly maps and other paper, I like to find and fix up old tube-type TV sets. I especially like the round screen sets. I have five (four color, one black and white). I'm looking for more. For me, there is nothing more satisfying than finding an old roundie on the curb and bringing it back to life. In fact, a couple of my round color sets have better pictures than the sets currently being madt today. If anyone here collects vintage tube electronics, I have one word of advice. Don't plug it in and turn it on. I can provide links for proper startup of these old relics. My main interest now is old TV, but if I see petrol that interests me, I go for it. Best to all.
