dim bulb tester - Zenith 775B

The old "dim bulb testers" usually didn't have just one Edison socket, but several sockets in parallel, at least three, and then this bank in series with the hot side of the line, both from the plug and to the outlet. This allows one to use a combination of tungsten filament lamps to provide the desired resistance, and saves buying odd wattages.
