![]() Within a year, other companies, such as Emerson, General Electric and Raytheon, all began selling transistor-based products. Texas Instruments devised processes for mass-producing transistors for their radios, and in the process, proved that transistors and their subsequent products could be affordable, more portable and more effective than vacuum tubes. ![]() The transistors, though, were what really made the project possible. The speaker, capacitors, and other components were created just for this project. 18, 1954.įrom start to finish, the race to create the TR-1 required innovative new parts that would fit inside a pocket-sized case, which would be small enough to really capture the world's attention. These radios went well with pet rocks, mood rings, disco, platform shoes, bell bottoms, Charlie's. Color rebounded and wild new shapes appeared. Thankfully, transistor radio design experienced a renaissance in the 1970's. This is the Internet Archive Radio Collection, a wildly diverse and massive collection of radio station recordings, broadcast captures, radio shows and. Together, the two companies created a radio called the Regency TR-1, which was announced on Oct. In the mid 60's the vast majority of made in Hong Kong radios were square, boring and came in a wide variety of color choices ranging from black to black. Texas Instruments used Bell Labs' breakthroughs in germanium transistors to develop a small, pocket-sized transistor radio, with the help of a small Indiana company named IDEA. Device manufacturers had been using vacuum tubes profitably for many years, so they were understandably leery about switching to transistors.īut Pat Haggerty, vice president at a company called Texas Instruments, was convinced that transistors were going to revolutionize the electronics industry. In 1954, transistors were proven but novel electronic components. If you’re interested in how superhet radios work, Transistor Superhet Receivers by none-other than Sir Clive Sinclair himself is an excellent book. ![]() Convincing manufacturers that this basic concept would work on mass-produced products, however, wasn't such a simple task. The S-74 is a reasonably simple six-transistor superheterodyne radio receiver, powered by four 1.5V AA batteries, with a channel switch and an internal antenna. Sony brand, 1970s ID: RNF3XH (RF) old radio ID: EJ9CBF (RF) broadcast, radio, radio sets, pocket transistor radio Stern Berolina de Luxe, made by VEB Stern-Radio Berlin, GDR, 1971, ID: BBN91D (RM) Vintage red plastic transistor radio. ![]()
