DescriptionThis plug-in module is formed by an open chassis on three sides and a Bakelite plug with 24 flat contacts on the fourth side. A handle is attached on the end of the chassis opposite the connector. A flange on each side holds a captive screw used for securing the module into one of the positions of the ten-module rack.
One 9-pin miniature vacuum tube socket, with a flange for a shield, and an 8-pin octal socket are mounted on the same end as the handle. Two pairs of phenolic solder terminal strips span the space between the two sides of the chassis to which passive components are soldered. Two toroidal transformers are mounted near the connector end of the chassis. Point-to-point wiring connects the connector, the tube socket pins, the transformers, and the solder terminal strips.
The tube complement is one 5965 and one 6145, both of which are missing.
