So what the heck is it? It's an all-tube single-channel graphic equalizer, made by Blonder-Tongue Laboratories in 1959. This is the front of the "spec sheet" I got along with the thing. The address given is "Newark 2, New Jersey", so zip codes did not yet exist. The controls for each band are little wheels, the edges of which stick out along the bottom; these are connected to upright plastic cylinders which are centered behind a vertical slot for each band of the frequency spectrum. Each cylinder has a spiral red stripe on it like a barber pole, so that when the wheel is rotated, the stripe shows as a red spot moving up and down in the slot... hence a "graphic" equalizer using rotary controls! Note the picture of a piano keyboard along the top, lining up with the frequency bands (one per octave).
