    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 transistor collector without an audio output transformer. One of several contemporary GE transistor radio models to employ this kind of speaker which was originally used in the 1920's because of it's high efficiency and high impedance.
