  • Shirtpocket transistor. High impedance speaker with reed suspended between 2 pole pieces, drives paper cone with a stylus, and is directly driven in push-pull by a pair of collectors, 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.

    The color is black; the white version has model number P851C.
