Post-Modulator Tuner, Type Y116, 1924-1925

By the late 1920s, radio tuners, detectors, amplifiers, and loudspeakers began to condense into one unit, housed within an attractive wooden or metal cabinet. The standalone nature of this radio tuner puts it in an earlier era of radio -- as a field for amateur operators, commercial technicians, and military communications experts -- rather than the domain of "passive" home listeners.
