Regency TR-1 Transistor Radio

This is the first commercially sold hand-held transistor radio. It was the brainchild of two separate companies: Texas Instruments of Dallas, Tx and Industrial Development Engineering Associates (IDEA). Both were leaders in the industry of high technology but neither had produced a device for the commercial landscape, looking to tap into the potential of this market these two designed in tandem what would become an icon of mid-century technology and today a highly sought after collectible. $500.
