Historical Background

 

Introduced by Sylvania in 1946, the 1N34 germanium diode has been in production ever since and continues to be the most popular and universally recognized diode available.  By the early 1950s, the 1N34 was manufactured by other companies, including CBS-Hytron, Radio Receptor, RCA and Raytheon. Both Sylvania and Raytheon marketed the 1N34 heavily to the hobbyist and experimenter market, and published numerous booklets containing 1N34 construction projects – best remembered is a simple AM radio, using the 1N34 with very few other parts.    

 

A large cylindrical ceramic case with green lettering was the earliest version produced by Sylvania.  The clear glass case style was introduced by Sylvania around 1950, with the label 1N34A. Raytheon used a proprietary number, CK705, for their early 1N34 equivalent diodes, but changed this identifier in the 1950s to 1N66 (See the photo above right).  Sylvania and Raytheon books from the 1950s list the CK705, 1N66 and 1N34 (A) as interchangeable.
