Rectifier stacks high voltage rca broadcast type nos
Type: 60138, Part No. 171 2032, Purch. Order No. 11-48661.
Each individual rectifier stack is marked "RCA" and "CEMC 171-2032" and is comprised of 8 stud type rectifiers in series with equalizing resistors and capacitors across them. Dimensions are 9.5" x 2" x 1.75". The entire assembly was painted black by the manufacturer so I can not identify the individual part numbers but they look like they can handle significant voltage and current. Ideal for their original purpose in a HV supply and/or for experimentation. I'm told they were made for a broadcast TV transmitter.
All four units are new old stock. I unwrapped one as you can see in the pictures the other three are tightly wrapped in plastic surrounded by packing-type brown paper.
I tested the one that I opened with a 12 volt bulb in series with a current limited 12 volt supply and the light only lit in one direction so the device I opened acts like a diode.
