RÁDIO ZENITH ROYAL 500 ANO 1955, ESSE RÁDIO É O MESMO MODELO DO QUE FICAVA NA CABECEIRA DA CAMA DO PRESIDENTE JK.

The Zenith "Royal 500" group of radios made up what must have been the longest running production of any one series of transistor sets. Beginning with the first 500 (7XT40 chassis) in 1955, and ending ten years later with the 555N in 1965, the 500 evolved and transformed through many versions of cabinet and chassis, until the final few models had become utterly unrecognizable from the earliest ones.
