Regency TR-1

The Regency TR-1 was the first commercially manufactured transistor radio, introduced in 1954. About 150,000 units were sold, due to the novelty of its small size and portability. Previously, transistors had only been used in military or industrial applications, and the TR-1 was the first to demonstrate their utility in consumer electronics. As a pioneering product of its time, surviving specimens are highly sought after by collectors.
