DescriptionPer Jack Ward, Transistor Museum -
"Raytheon CK851 and 1N66 (1 piece each), silicon diffused junction rectifier (CK851) and germanium gold bonded diode (1N66). Mid-1950s. These units represent additional examples of the variety of case styles and colors used by Raytheon for mid-1950s semiconductors. Typically, Raytheon used Red case color to indicate silicon device and Blue case color to indicate germanium device, and that approach is demonstrated by the two devices in this lot. Common – although in production for only a few years, these types of Raytheon semiconductors were manufactured in substantial quantities."
