Description

This 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.

Three vacuum tube sockets and one 14-pin miniature round relay socket are mounted on the same end as the handle. Five phenolic solder terminal strips span the space between the two sides of the chassis to which passive components are soldered. Point-to-point wiring connects the connector, the tube socket pins, and the solder terminal strips.

The tube complement is one 0528, one 2D21, and one 5687.
