| Notes | The General Electric P808C is a battery operated portable AM receiver. The AM band frequency tuning range is 540 to 1600kHz. Has earphone jack that disconnects the speaker for private listening. The P808C is part of the following family of models:
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. Uses Qty(5) large TO5 transistors, with audio output transistor operating as a Class A amplifier directly driving the speaker. Normal size resistors and capacitors are used (similar to sizes used in tube radio's). |
