The RCA 2N109, introduced in 1955, is a Germanium PNP Alloy Junction transistor designed for audio frequency amplification. This historic component became a workhorse in the electronics industry for over a decade, valued for its affordability and reliability.
It found extensive use in the audio output circuitry of many early transistor radios from manufacturers like RCA, Emerson, and Westinghouse. Notable applications include the Crosley 'Radio Disguised as a Book' series and the Fisher TR1 Transistor Preamp, one of the first all-transistor high-fidelity products.
The 2N109 was also promoted by RCA as a general-purpose, inexpensive device for hobbyists and experimenters. It was manufactured exclusively in a short-leaded version designed for socket mounting, with case styles available in black metal (early) and silver metal (later).
This transistor's historical significance lies in its role in the early development and adoption of transistor technology in consumer electronics and hobbyist projects.
