Back in the 50's when I was still in high school, there was a local TV shop that threw many of their irreparable TV chassis, mostly ones taken on trade-in, out into a dump pile. They would let us pick through the stuff and we could usually have anything we wanted. I got many power transformers and tubes that way. I could have collected zillions of black beauties with the colour bands, since that seemed to be the most common type of caps in old TV sets of that era. (20-20 hindsight!).

Most of the time I discarded the black beauties in particular because they often had cracks in the plastic with oil dripping out, and they seemed to me to crap out more often than the old fashioned wax impregnated cardboard tubular types. Of course we are talking about caps that had seen thousands of hours of service before the TV finally gave up the ghost, and then used in ham applications that no doubt exceeded their intended specs.
