A Hickock Crystal Controlled Microvolt Generator. This piece of equipment, as far as our research goes, was used to service HAMM radios. We also found out that "crystal controlled" was the company's way of insinuating that it was more precise than its competitors. Of course, it wasn't true. Marketing at its finest.
As you can see, this lamp has knobs all over it. The knob at the bottom actually spins the wheel in the center. The toggle switch at the bottom has been wired to turn the lamp on and off. The base is roughly 1.5 feet wide, and a foot tall not including the lamp necks. Its a big guy, so you may need to make some room in the man cave for this one.
