The Collector's Guide to Antique Radios indicates that Amrad was bought by Crosley but produced radios under the Amrad name until 1930. Amrad Model F516 is dated to 1936 (by tube type) and refers only to the Amrad name. However there is a Crosley Model 516 which uses similar chasis but with oval dial instead of round. The schematic for the Crosley 516 is exactly the same as that for the Amrad F516.

Does anyone know if radios were made under the Amrad name after 1936?
