This listing is for a lot of vintage CADC metal-can crystal oscillators, marked with various frequency values such as 7718.52, 7431.04, and 7333.33. These units appear to have been manufactured for use in military or aerospace applications, possibly within Central Air Data Computer (CADC) systems used in aircraft avionics during the Cold War era. Each oscillator is housed in a robust metal enclosure and displays precision-engraved markings including “CADC, ” date codes, and serial identifiers. The condition is consistent with long-term storage, showing some surface wear and oxidation typical of surplus parts of this age. Whether you’re a vintage electronics enthusiast, a history buff, or a creative upcycler looking for unique industrial components, this set of oscillators would make a distinctive addition to your collection or project bench.
