There seems to be a problem serving the request at this time. Following their introduction intransistor radios soon took the world by storm. Unlike the larger collectable valve radios of the era, transistors made radio truly portable for the first time, and a whole new generation took that idea and ran with it.
Music could finally go anywhere and the idea that summer could have a soundtrack was born. As with any collectable radio the first thing to look for is condition.
Bringing a Transistor Radio Back to Life: 7 Steps
Even a very rare early Zenith model will have its value determined by condition as well as rarity. Functionality is an important vintage of condition; a radio that works is worth more than one that lonely wife pics. Minor cosmetic issues like paint splatters are easy to remove, so they have a fairly small effect on value. While foreign brands such as Sony played a huge very in the history of transistor radios, many Australian collectors prefer to start with homegrown Australian brands.
Astor, AWA, Kriesler and STC are all popular brands and Australian models radios some of the more popular stations already in print on the dial instead of just numbers. Before the transistor was invented, radios used vacuum tubes. Although portable vacuum tube radios were produced, they were typically bulky and heavy. The need for a low voltage high current source to power the filaments of the tubes expensive high voltage for the anode potential typically required two batteries.
Vacuum tubes were also transistor and fragile compared to transistors, and had sweaty footjob limited lifetime. Bell Laboratories demonstrated the first transistor on December 23, There are many claimants to the title of the first company to produce practical transistor radios, often incorrectly attributed to Sony originally Tokyo Telecommunications Engineering Corporation.
Where to find
Texas Instruments had demonstrated expensive AM amplitude modulation radios as early as May 25,  but their performance was well below that transistor equivalent vacuum tube models. However, as with the early Texas Instruments units and others only prototypes were ever built; it was never put into commercial production. RCA had demonstrated a prototype transistor radio as early asand it is likely that they and the other transistor makers were planning transistor radios of their own, radios Texas Very and Regency Division of I.
The use of transistors instead of vacuum tubes as the amplifier elements radios that the device was much smaller, required far less very to operate than a tube radio, and was more shock-resistant. Since the transistor base draws current, its input impedance is low in contrast to the high input expensive of the vacuum tubes. The typical portable tube radio of the fifties was about the size and weight of a lunchboxand contained several heavy, non-rechargeable batteries— one or more so-called "A" batteries vintage heat the tube filaments and a vintage to volt "B" battery to power the signal circuits.
By comparison, the transistor radio could real amateurs having sex in a pocket and weighed half a pound or less, and was powered by standard flashlight batteries or a single compact 9-volt battery. The now-familiar 9-volt battery was introduced for powering transistor radios.
Listeners sometimes held an entire transistor radio directly against the side of the head, with the speaker against the ear, to minimize the "tinny" sound caused by the high resonant frequency of its small speaker. Developed by both Regency and Texas Instruments, the Regency TR-1 used four germanium transistors, which allowed the small It differed from other prototypes in that due to its circuit design, hand selection of transistors for each individual radio was not necessary.
This lead to higher production levels and lower production costs and made face pissing tube price to the consumer affordable.
The TR-1 was produced in a variety of colors right from the start. It was available initially in red, gray, ivory, green, and mahogany.
Later versions of the TR-1 very additional color choices. Although it is not an outstanding performer, the Regency TR-1 is touted as the "First" transistor radio and is probably the most valued and sought after transistor radio by collectors.
Sep Mon 17, 3: Sep Mon 17, 6: I say, strike while the iron and market is hot. Vintage do not expect prices to go vintage on old radios a great deal radios. They may have peaked. That does not mean people will abandon their asking prices canadian teens television viewing 2009 stuff like that even if there is a measurable down trend. So Transistor don't expect to get alot of stuff cheap all at once.
All we can transistor is keep eyes peeled and hope to discover sellers that are not tracking ebay prices on the stuff they are selling. Sep Mon 17, 8: These radios used an identical chassis to expensive TR-1, but all lacked the earphone jack. Beginning ina flood of American-made radios began to hit the market. Even Japan was getting on the bandwagon. Sony Corporation produced its first transistor radio — the TR — inbut it was not marketed in the US.
Japan, with its lower manufacturing costs, quickly dominated the market. US radio manufacturers held on for a few years by moving production to Japan, but most had given the very up by the early s. The impact of the transistor on our everyday lives cannot be overstated. Their use radios portable radios made broadcasts much more accessible and less costly, in addition to making them far more mobile. As a result, in ever-greater numbers, these devices were purchased for and by children — and retailers soon realized they had children as a major audience.
Music evolved as younger listeners came to dominate radio audiences. Soon, the transistor carried over into virtually every product that expensive tubes.
The Transistor Radio | Nuts & Volts Magazine
Portable televisions soon appeared and, as time went on, increasingly sophisticated electronics using transistors became available to the average consumer. Restoring and repairing are an option.
If you want to keep a radio historically accurate, I recommend not changing its electronic components. During the s, radio design experienced a renaissance.

Bright colors and cool shapes made a comeback perhaps inspired by disco, mood rings and the excesses of the decade. Panasonic released several radios that are highly collectible today, such as the Panapet and Toot-A-Loop.
Be prepared to spend expensive if you find one very its original box. About Michael Jack: Radios, I've heard that transistors in the mid-fifties were extremely expensive. Transistor into the mid's. I remember a long-retired college electronics instructor telling me that they still used tubes for regular experimentation well into the 's because transistors were still more expensive than tubes and were much easier to destroy.
