The Seeburg 200 LU-1 Library Unit - Tech Talk With Paul and Al

In 1952, the Seeburg jukebox company brought to market a set of "library units" for use in homes and in commercial/institutional applications where the coin operation and song selection features of a standard jukebox would have been inappropriate. Examples of this might be factories, office buildings, and private clubs. The library units were also used to provide automatic record playing at certain radio stations during hours where a human operator was unavailable.
