Old Oscilloscopes
Anyone here like old oscilloscopes? I was wandering through this used electronic parts store's yard today and found a really old one sitting in the rain, and I had to rescue it. "Dumont Cathode-Ray Oscillograph" model 274, it uses the 5BP1-A crt. It looks at least 1940s. It uses two #80 tubes, I don't know when they stopped using those old tube designations, but I thought it was sometime in the 30s. Despite being out in the rain it is actually clean inside, but it uses some capacitors for which locating replacements would be nearly impossible: 5mfd at 1500volts and such. I don't really need another working one anyway, I might just put this ontop of a TV and look at it.
