O.M.G.S. Suburbia, 1964
Approximately 5-3/4 inches / 146 mm wide.
As emblazoned on the front in big type, this radio has twelve (count 'em!) transistors. The performance is very good, but I suspect at least a couple of the twelve transistors in the circuit may have been added for marketing purposes.
Back in the very early days of radio, buyers came to associate more tubes in a radio with better performance and higher quality. It took only a few years before some unscrupulous manufacturers started using weird designs or "dummy" tubes to artificially inflate the tube counts of their radios. It wasn't long before transistor-radio makers began doing the same thing with transistors in the 1960s.
