Physical Description
The 6A2 chassis is constructed on a stamped steel frame designed for installation in a tabletop cabinet. It includes a tuning capacitor, IF transformers, and a six-tube layout providing additional circuitry compared to simpler designs. Controls for tuning and volume are connected to the front panel via shaft extensions. Internal construction uses point-to-point wiring with components mounted on terminal strips and tube sockets attached to the chassis.
History
Admiral Corporation was a major U.S. manufacturer of radios and televisions during the 1940s and 1950s. The 6A2 chassis represents a slightly higher-performance design than the common five-tube radios of the time, offering improved sensitivity or audio output depending on configuration. It was used across multiple Admiral models and remains of interest to collectors and restorers.
