  • Notes

  • United Reproducers Corp. manufactured five models of it's Series 20 Peerless receivers.  In addition to prices and cabinet styles, the models differed by the type of built-in speaker: 

    Peerless 21 was offered with the option of either a standard dynamic speaker or a Kylectron (United Reproducers' brand of electrostatic speaker).

    Peerless 22 was equipped with a standard dynamic speaker.

    Peerless 23 came with a Kylectron speaker.

    Peerless 24 was produced with a 12-inch dynamic speaker.

    Peerless 25 was a radio-phonograph combination which had a Kylectron speaker.

    Production began in late 1928 and, although the company went into receivership in late 1929, a major Kylectron advertising campaign continued until May 1930.  United Reproducers ceased operation before the end of 1930.
