Shown here from a hundred years ago is one of the first examples of a radio-phonograph combination. According to the August 1922 issue of Popular Mechanics, the set was a one-control radio receiver with a super-amplifier (using three tubes to accomplish what had previously required five) mounted in the cabinet of a console phonograph. The radio was connected to the phonograph’s horn, and no ground or antenna connection was required, thanks to a special loop antenna.

With a single control, the owner simply tuned the set to the correct wavelength.
