1961 Zenith Royal 755

1961 Zenith Royal 755LK. This was one of Zenith's lunchbox sized transistor radios, and the last variation of the 755 series. The LK featured a 'battery saver' mode which aimed to extend the life of the batteries by reducing the voltage to the audio circuit. These are excellent performing radios, and were pricey at almost $80 new!
