![]() The TR-1, despite 140,000 being made and selling for $49.95 (~$465 in 2018 dollars), could not catch the heat of tube-based competitors. Due to the use of transistors, there were no more vacuum tubes to worry about. It could be easily carried in a shirt pocket, while other radios of the time period were much larger and were barely considered portable. The TR-1, originally announced in October 1954, was instantly seen as a novelty due to its small size. The TR-1 The TR-1 wasn’t only the first transistor radio – but one of the first transistorized consumer products. After refining the circuit and making it more easy and cheaper to produce, the Regency TR-1 radio was born. While none were interested, IDEA picked up the idea. TI developed a transistor radio circuit and pitched the idea to several manufacturers. IDEA, under the “Regency” name, produced antenna amplifiers prior to the TR-1. Just a year later, TI was able to purchase a patent license to manufacture transistors to the Bell System’s (specifically Western Electric) specifications.Īt the same time, the Industrial Development Engineering Associates (I.D.E.A.) of Indiana was manufacturing antenna amplifiers under the name “Regency”. Texas Instruments, at the time, was just a small company that was newly formed as a spin-off of Geophysical Service Incorporated in 1951. However, Texas Instruments paired up with an Indianapolis-based company to produce the first consumer gadget to employ the new technology. The early transistors were unreliable and, in some applications, would not work. While you would think that the transistor would be an overnight success, finding uses in everything, you would be wrong. But what about technological breakthroughs? Introducing the Regency TR-1 transistor radio…īefore the transistor, vacuum tubes were the “norm.” They were found in everything ranging from radios to television sets to large computers (like SAGE.) However, scientists at Bell Labs – the research laboratory for the Bell System – invented the transistor in 1948. The middle class is rising, with suburban areas and so-called “Levvitowns” popping up all around the country. The economy is booming – more cars are being sold, homes are being constructed, and new inventions and technological breakthroughs are happening all the time. Buyers seeking lower pricing may search "Eric Wrobbel books" online.The year is 1954. WORTH EVERY DIME eBay is taking an ever-larger slice of sellers' proceeds with increasing prices as a result.
