Historical
Background
During
the late 1950s and 1960s, Westinghouse became a world leader in the
manufacture of high power silicon transistors and rectifiers. Research and
manufacture of germanium transistors had been started in the mid 1950s, but
was not a major business for Westinghouse. Of note is the manufacture of
low frequency (audio and IF) germanium transistors, primarily to support
the substantial Westinghouse commercial radio manufacturing business. By
the mid 1960s, Westinghouse had ceased the manufacture of the germanium
radio transistors, most likely to focus on silicon power devices. Your
Westinghouse 2N60/2N609 transistor represents an important, though
short-lived, chapter of semiconductor history.
Use your 2N60 as a general
purpose audio amplifier – the 2N609 is a higher gain equivalent to the 2N60
and can be used in similar audio amplifier applications. These are rare
and historic devices and will make a terrific addition to your collection
of early semiconductors.
