Tuned radio frequency receiver. This 1920s TRF radio manufactured by Signal is constructed on a breadboard. Tuning a TRF receiver, like this 5 tube Neutrodyne set from 1924 with two stages of RF amplification, was a complicated process. The three tuned circuits, controlled by the 3 large knobs, had to be tuned in unison to the new station.
