This is a generic module rack with 10 modules installed, seven with two vacuum tubes. One of the modules is empty, and two are missing a tube. There are tags on each of the modules, numbering them E14-5-1 through 10. There are nine coaxial connectors with cut wires and some open connections. There are also numbers on each of the cooaxial connector spaces, which read J1-1 through J10-4. At one end there are two terminal strips on the top, two at the bottom, and one on the side of the chassis. "PIUMP #447 E 14-J" is also engraved on a black plastic label at the bottom of the rack. There are five sets of indicator lights along the bottom. Each set has one red light and one white light.
