Grebe Audio Frequency Amplifier, Type RORK, 1920-1923
01
Artifact Overview
Early radio broadened the cultural horizons of its users beyond the town or county line--the audio frequency amplifier promised to reach even further. While amplifiers are often thought of as devices that only increase the volume of sound, the frequency amplifier was used to enhance weak radio signals. By increasing the receiver's performance, long-distance stations could be received.
