- Notes
-
GE General Electric P1731B AM radio with leather case.
Very unusual is the application of a high impedance reed speaker with paper cone. Driven directly 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.
