Radio Wallah
Alan Kastner's transistor radio site was one of the original go-to websites for radio enthusiasts, and it offers an impressive collection of information on 1950s American, European, and Japanese manufacturers and models. Each page contains beautiful set images and detailed reference information (on models such as the Hoffman P410 and P411 series, Lafayette FS-110, Sanyo SC-3, Sony TR-66, Standard SR-F23, and many more).
