I got this old amprobe a few years back from a friends grandpa and just got around to checking it out. From the looks of it I don’t think this thing has ever been touched let alone used. I’m guessing it’s from the 60s or 70s. What’s crazy to me is that ancient Union-Carbide AAA is still showing some voltage 50 years later!
