Ancient Micronta R-4002 VOM

I somehow ended up with this ancient Micronta R-4002 VOM. It's an interesting very early Radio Shack VOM. It says "1955" on the meter card, right next to the handwritten serial number. It's 20,000 ohms per volt for DC, 8,000 ohms per volt for AC.

Simpson model 59 panel meter, 150V AC

I plan to monitor the AC power line voltage in my shack with a Simpson model 59 AC panel meter that I picked up as surplus from someplace or other. 


But it's got an oddity - a external 0.0025 µF capacitor hanging off the back of the meter.
