General Transistor Corp. - GT763 - Vintage Early Case Style TO-5 PNP Transistor Germanium

General Transistor Corp. - GT763 - Vintage Early Case Style TO-5 PNP Transistor Germanium A vintage Germanium PNP transistor in a TO-5 metal case style. The General Transistor (GT) 763 is a vintage PNP Germanium transistor, manufactured during the 1950s by General Transistor Corporation. It is housed in an early TO-5 metal package and was designed primarily for computer and switching applications as well as use in high-frequency applications, such as RF amplifiers, oscillators, and computer switching circuits during the late 1950s and 1960s. General Transistor Corporation, which produced the GT763, was active from 1954 until merging with General Instrument (GI) in the early 1960s, specializing in high-quality germanium devices for the growing computer market.
