  • Notes
  • The General Electric P807J is a battery operated portable AM receiver. The AM band frequency tuning range is 540 to 1620kHz.  Has earphone jack in back that disconnects the speaker for private listening.  9 V block battery Eveready No.266 required.

    The P807J is part of the following family of models:

    P808A P808B, C, E, G, H, J, S, T White
    P809B P809C, E Green

    Has high impedance speaker with reed suspended between pole pieces, drives paper cone with a stylus, and is directly driven by a single ended collector, without an audio output transformer. One of several contemporary GE transistor radio models do employ this kind of speaker which was originally used in the 1920's because of it's high efficiency and high impedance.
