This record contains one electronic beam part. It is composed of a triangular-shaped base with curved edges. From this base there are three metal rods that hold up a circular copper plate that has holes in it. Between the base and the copper plate, there are various ceramic and copper components attached to the base. There is also a pin connector that stands up on the base. The copper components are fluted tubes that correspond with the holes on the copper plate above it.
