These giant selenium rectifier plates
I recently picked up an ancient PACO B-10 “Power Supply / Battery Charger” from the Columbus Hamfest. I wasn’t sure what was in the thing, but turns out there’s not much.
These giant selenium plates, however, are a thing of ancient beauty. The whole thing looks like it’s era, a mash of wire, transformers, and rust. Stay tuned for a more complete teardown and other photos of this device.
