This record contains one electron beam enclosed in a glass cylinder. The electron beam is cone shaped. One end of the electron beam is closed with several claw-like protrusions and a circular component attached. The other end of the electron beam has a single channel tube protruding from it. There are several groupings of pins on the narrow end of the electron beam with wire wrapped around them, and connected to small circular components on stands.
