Raytheon CK784 Transistor  
Written by AnubisTTP on 2020-11-23  


In the early days of the transistor era, Raytheon produced a number of small audio frequency devices for use in the hearing aid market. The Raytheon CK784 is one such device; a tiny metal can PNP transistor intended for use in audio amplifiers. The CK784 is approximately half the size of Raytheon's popular hobbyist-friendly CK722 transistor, and is small enough to encroach on the size of a modern TO-92 device. Raytheon's iconic blue paint, also popularized by the CK722, is present and accounted for.
