Vintage Transistor Radios of the 1950s and 60s

May 2nd, 2008

Michael Jack, whose personal Flickr website is a member of our Hall of Fame, is a collector of vintage transistor radios.

Perhaps you recently saw a picture of a cool looking pocket radio from the early 1960’s and were reminded of your carefree, youthful days? Maybe it was the pastel colors or atomic aged designs that caught your eye? Or the chrome highlights that attracted your attention? Nonetheless, you find yourself actively seeking them out at the local flea market or surfing eBay for a good deal.

windsor & selfixWell, be warned! If you buy one transistor radio it will most likely grow to two, then three. By your fourth radio you will be considered a “collector” and will be hooked! There will be no turning back from the appeal of these mid-century, technical and artistic marvels.

Before spending too much money I recommend you take some time, do your homework and educate yourself. Then have fun and collect what you like. Although the main focus of this article is to broaden your knowledge base, make sure you don’t just collect for investment or get caught up in only possessing what are considered “must haves”. Sure, you’ll want some key radios but make sure you collect what you like. Have fun and buy radios that appeal to your personal tastes.

I suggest spending some time on the internet or scanning the pages of the few transistor radio price guides to research makes and models. Most of the price guides on the market were released well over ten years ago during the first “wave” of transistor radio collecting. They predate eBay and the quoted prices are often higher than present day values. What we’ve realized over the years is that these radios are not as rare or scarce as once thought. There are a few exceptions which I will talk about shortly.

1950s Transistor Radios: The Early Years

regency tr-4Generally, the most collectable and historic transistor radios are those made in Japan from 1956 to 1963 and America from 1955-60. One easy way to date a transistor radio to this period is to look for small triangles or circles between the 6 & 7 and the 12 & 16 on the dial. These are CD marks, which appeared on all radios manufactured or sold in the U.S. from 1953 to 1963. CD stood for Civil Defense and was taken very seriously in the 50’s and 60’s due to the communist “red scare.”

To counteract the potential for a Russian air attack on North America the US Government enacted the CONELRAD program, which stood for CONtrol of ELectromagnetic RADiation. CONELRAD established two civil defense frequencies, 640 and 1240 kilohertz. During times of emergencies, all stations except the CONELRAD stations at 640 and 1240 AM would cease operations (note that some Japanese radios made by Sharp and Hitachi during the late 50’s left out the CD marks).

American companies were the first out of the solid-state-radio gate with the release of the Regency TR-1 on Oct 18, 1954 (it sold well into 1955 and 1956 as the re-designed TR-1G and TR-4). As a transistor radio collector I think it’s important to have one example of this historic radio in your collection. They can be found on Ebay ranging in price from $300 to $1000 depending on color. The more basic ivory and grey cabinets will fetch less money than the “mandarin” red and black.

toshiba 6-tpFor a brief period TR-1s were released in very attractive pearlescent pink and light blue colors as well as swirled, jade green and mahogany. These later examples command top dollar on Ebay. If you really want to find a great deal on a Regency TR-1 I suggest frequenting your local flea markets, garage sales and antique markets. It may be a few years until you find one but think of the fun you’ll have searching and the money you’ll save. I found a red TR-1 at a flea market two years ago and only paid $100.
The TR-1 and TR-1G used an odd 22.5 volt battery which can be found in limited quantities today but are pricey.

Early Zenith radios like the Royal 500 series are also worthy of having in a collection. The first Royal 500 was hand wired and had a metal chassis! The fifth generation Zenith 500 was the 500H. It has a large oval speaker and is considered to be the best sounding/performing portable transistor radio ever. If you’re into high performance you may want to consider this one. An early handwired 500 will fetch more money than the later versions.

Other collectible American-made radios are from RCA, G.E., Admiral, Motorola, Magnavox, Philco, Raytheon, Arvin, Sylvania and Emerson etc. American made radios tend to be slightly larger than their Japanese counterparts. Most U.S. radios would be considered “coatpocket” sized – too big for your shirtpocket but too small to be classified as a portable. Many were also larger, leather-clad portable sets like the Zenith Royal 750 and Raytheon 8TP-1.

emerson pioneer 888One of the most popular and attractive coat pocket radios were/are the Emerson’s 888 series. Emerson released several models in this series from 1958 to 1960 such as the Vanguard, Pioneer, Explorer, Satellite, and Atlas – all named after various U.S. space programs. These radios can be found in great numbers today, and are terrific looking and often reasonably priced (typically from $20 to $100 depending on condition).

The Japanese Radios: Full Miniaturization

Although Japanese manufacturers were a bit behind the American companies in producing transistor radios they quickly caught up and exceeded expectations. The first Japanese transistor ever released was Sony’s TR-55. At the time Sony was a brand name, the company itself was called Tokyo Tsushin Kogyo. The TR-55 is incredibly rare today. It was only sold domestically in Japan while 50 units were imported in Canada by General Distributors (GENDIS). You may never encounter one of these in all your years of collecting.

The Sony radio that seemed to change the entire electronics world forever was the TR-63. Released in 1957, it was considered the world’s first, truly pocket-sized radio and was the first to utilize all miniature components. It was also the first Japanese radio to be imported into the U.S. (several other early Sony radios were sold in Canada in 1956). Several TR-63s appear each year on eBay but expect to pay top dollar for one. Even examples with cracks or chips can fetch $400. Those in mint condition will realize higher amounts.

Once Sony opened the U.S. market, other names like Toshiba, Hitachi, Sharp, Standard, Sanyo, Matsushita (Panasonic), Mitsubishi, Aiwa, Realtone, Global, and Zephyr arrived on North American shores and attracted the youth market with their smaller, more affordable and more colorful pocket radios. The simultaneous arrival of imported pocket radio and rock n’ roll conspired to change the electronics industry forever!

By the late ’50s and early ’60s, many American companies had opted to have their radios made in Japan but retained their American brand names, such as Trancel, Penny’s, Channel Master, and Bulova. Even giants like Zenith, RCA, Motorola, Philco, and G.E. had their radios made in Japan. They could no longer compete with the lower prices and more attractive designs coming from Asia.

Classic Design Features

sony tr-55One of the classic features of Japanese radios was reverse painted plastic. Reverse (back) painting was a very popular method of ornamenting transistor radios between 1958 and 1962. By painting all artwork on the inside of the clear plastic dial cover, there would be no wear or damage to the most attractive features of the radio. A smooth protective surface remained on the outer dial.

This process also gave the radio a three dimensional appearance. The depth and palette of colors were quite breathtaking. Gold on white, black accents, bright red and powder blue along with geometric shapes like starbursts, chevrons, jet wings, diamonds and parallel lines make reverse painted radios visually stunning and highly sought after by collectors. Makers like Toshiba and Crown were exceptional with their creative use of reverse painting.

Even Japanese radios without reverse painting are highly collectible. The Sony
TR-610 (which sold almost 500,000 units worldwide), with it’s sleek cabinet and round speaker grill, spawned a host of imitators like the Realtone TR-1088 “Comet”. These radios can be found in abundance today and range in price from $50 to $150 depending on condition and color.

In your travels you may even encounter pocket radios called “Boy’s Radios”. Japanese firms were hit with both a domestic export tax and a North American import tax on any AM radio having three or more transistors. This would have put a dent in Japanese radio sales – forcing retail prices to climb. Solution? In the early 60’s Japanese manufacturers developed AM radios which could operate on only two transistors. They were marketed as “toys” rather than electronic devices thus stepping around the taxes!

boy's radio japaneseThese radios would either have Boy’s Radio or Two Transistors prominently and proudly displayed on the cabinet. In many cases, the cabinets were identical to “real” radios with 6 transistors. Performance was less than stellar but these radios could still pick up local stations. Teenagers were swayed by price and appearance anyways, and performance was low on their list. Boy’s Radios show up often on eBay and range in value from $25 to $70.

With any transistor radio from the 1950’s or early 60’s it seems that the brighter the color the higher the price. Cool 50’s shades like robin’s egg/powder blue, seafoam green and bright red or yellow command higher prices. Black and ivory cabinets are considered less attractive by some and may reduce a radio’s value on the collector’s market.

Other Tips For Collecting Transistor Radios

Of course condition is key in valuing a radio as well. Finding a radio with its original box, leather case, earphones, owner’s manual and warranty card/sales slip will inflate it’s worth. You may have to dish out twice or three times a radio’s book or eBay value with all those extras.

Be sure to examine the cabinet closely when making a purchase. Small hairline cracks or chips are often found in the corners. These pocket radios experienced very active lives during the 1950’s and 60’s. Many were taken to picnics, ballgames, schools and other social outings. They might have been dropped, left in the sun, damaged while trying to replace the batteries or just plain neglected by their owners.

Some collectors refuse to buy damaged radios. Others, like myself, are not troubled by buying less than perfect examples. The time spent restoring and repairing is very rewarding and it’s much easier on the pocket book! (A damaged radio will most often realize half of its book or auction value) There are several products on the market like plastic repair kits, polishes, cleaners and electronic replacements to bring a radio back to life if you so desire. If you want to keep a radio historically accurate, I recommend not changing its electronic components….the choice is yours.

toot a loopRadios made in Hong Kong during the mid to late 60’s are not highly desirable. Gone were the fancy colors, atomic age designs, chrome and reverse painted dials. In my travels I’d say that over half of all the radios I encounter were made in Hong Kong. Most often I pass them up unless the price tag is $5 to $10. Perhaps in another ten years these radios will become “collectible.” However, if you see one and you like it….buy it and enjoy it!

During the 1970’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 collectable today such as the Panapet and Toot-A-Loop. They can be found at flea markets or online auctions ranging in price from $10 to $50. Be prepared to spend more if you find one in it’s original box.

    I have a Vornado 2 band 8 transistor. The bands are KC and MC,and i am trying to date it. Any information would be helpful.

  6. Oscar Johnson Says:

    Hi,
    I have a working Zenith Royal 400 radio with the leather carry case. Model R400Y. Z645959. Do you know the approx. date and how mant transtiors this has. I need to find a set of earplugs for it.. Any value for this radio. Black and looks good.
    Thanks,
    Oscar

  7. Michael Jack Says:

    Hi Oscar, for the best info on Zenith transistor radios you might want to check out Gary Ball’s excellent Zenith radio website. He knows his stuff! http://www.garysradios.com/

  8. Michael Jack Says:

    Hi Richard Foster. what model # is your Zenith? Once again I’d refer you to Gary Ball’s informative Zenith website. You will most certainly find what you’re looking for there.
    http://www.garysradios.com/

  9. Michael Jack Says:

    Hi Darrell, a model number for that Vornado radio would help. Also, look and see if there are any Civil Defense marks (CD marks) on the tuning dial. If a radio was made between 1953 and 1963 it was required to have these marks on the dial (found between the 6 & 7 and 10 & 16). Most often they appear as small triangles.

  10. John Smith Says:

    I am trying to find out information about a transistor I have,
    it is a National, made by Matsushita E. Ind. Co.Ltd – 8-transistor 2 band radio Model T-22 U or T. It is pale blue made of bacolite or plastic and has a leather protective case.

    I have looked on ebay and several sites but unable to see the like, can you help

  11. John Smith Says:

    re my previous comments about the Matsushita transistor radio, has anyone any comments or information?

  12. Michael Jack Says:

    Hi John, I am not familiar with that model but I do have a Matsushita T-13 which dates from 1961-62. Perhaps yours is from the same time period as the model numbers are close? If I ever find out more I will report back.

  13. randy Says:

    I have a woolworths Audition 14 transistor radio.
    Would like information or possible worth of radio.
    Still in box with batterys rayvac type. Never used it appears.
    Intrutions with woolworths on info.And $9.99 price tag.
    All seems in pristine condition.

  14. William McMillian Says:

    I recently purchased an emerson model 869 transistor radio.The case is in great shape but it doesn’t work.I paid 30.00 for it.Is that within range?

  15. Doris Wood Says:

    I have a Candle Model ATR-801 … 8 transister radio, turquoise in color with original box and accessories, but no instructions … it plays well. I’m trying to research it to find when it was made. Much thanks, Doris

  16. Michael Jack Says:

    Randy: regarding the Audition 14 transistor radio. It probably dates to the late 60′s and I bet it was made in Hong Kong. By that point transistors were very cheap to manufacture so companies would “beef up” their transistor counts in order to attract consumers. The idea was (and still is) – more is better. Many of these extra transistors were not actually wired into the circuit or performed redundant duties.
    These radios are still very plentiful and are not in demand by collectors thus they do not fetch big dollars. All the 12-14 transistor radios I own cost me $5 to $10

  17. Michael Jack Says:

    William McMillian:
    That sounds like a great price for an Emerson 869. Good find. It’s an early Emerson solid state radio…..mid 1950′s.

  18. Michael Jack Says:

    Doris Wood:
    The Candle ATR-801 is a very nice looking radio. I have one that’s orange….
    you can see it and get more info here – http://www.flickr.com/photos/transistor_radios/2856955680/

    I believe it’s from about 1959. If you ever want to find it a new home I’d be happy to discuss it with you :)

  19. Richard Links Says:

    Hi, Michael:

    Absolutely a terrific article, so THANKS!

    BTW, a year ago, I stumbled upon a magnificent example of the Regency TR-1 in Mandarin Red at a local (Berkeley, CA) flea market for $5.

    Yes, that is FIVE DOLLARS.

    Unbelievable discovery and it is like a dream “find” for me!

    Cheers!

    Hi Richard
    Thanks for the kind words on the article.
    Nice find on that red TR-1. Those types of finds are one in a million but the do happen. One of my best flea market finds was a Toshiba 6TP-31 (the bathroom scale radio) for $10.
    Here’s the link to it….

  21. Thomas Ensminger Says:

    I feel like I know you but I dont–you seem to be over involved in radio as I am. Tell you a little story. When I was about 20-I worked for a construction company. It was my job to crawl under buildings(since I was a small guy) and prepare them for jacking them up. On one site I found an old transistor radio that I learned later was 10 yrs. old.- When I got home; just for the fun of it-I cleaned its terminals and put in a newer battery and surprizingly it worked! (AM was a bit static-filled back then) but these radios were also durable. I have no idea how that radio got where it was. This was in New Jersey/ I live in Maine today. Tom

  22. Kristan Soboleski Says:

    I don’t know anything about radios but I’ve been trying to find any info I can get on a radio called Flippy FabuLLOYD’S. It’s from 1970 and the info I did find (very little) said it was orange/cream and white. Mine is purple/tourquois and white. I was wondering if it’s worth anything. It’s in excellent condition and works perfectly. I have been trying to find an e-mail address for you so I could ask you but I guess this will have to do. I hope you get this and can get back to me. Thank you, Kristan

  23. Joul LaFleur Says:

    Collecting transistor radios has been a great experience for me. Born in 1960 at the end of the baby boomers, collecting while at the same time learning about transistor radios has given me an awesome snap shot of that day and time. I just enjoy listening and tinkering at the end of my day with a sound and radios so captivating and rich. 426 radios and counting. Thank you for the Guest Column, you are a short cut on my desk top!

  24. michael jack Says:

    Kristan, those radios are a great example of 70′s radio design. They are not worth big $ on the collector’s market, often they will fetch $20 or so on Ebay depending on the condition. Most of the time the lettering is worn off on the sides. There were a few variations with the hand strap and it was available as AM only or AM/FM.
    I have two of these in my collection……

  26. John R Says:

    I have only become interested in old radios in the past year, starting with tube radios. I have just recently started looking at transistor radios. I read your article just yesterday and it was very informational. I attended an auction last night and found a box lot (12 radios in all) of old transistors. The box contained, to name a few, an RCA 1-TP-2E, an RCA 3 RH22G, a Zephyr ZR-620 and a Zenith Royal 500. With the exception of a few most of these radios have been very well taken care of. Whoever owned them, must have loved them. And I can see why, they are very cool looking. Apparently no one else in attendance at this auction was very interested in transistor radios because I got the box on an opening bid of just $10. Was I ever surprised. I owe you a huge thanks. It was your article that informed me of some of the better collectable radios. So THANK YOU, THANK YOU, THANK YOU for sharing your knowledge and passion.

    I do have a quick question. Do you have any idea where I can find a 4 volt battery? The tag on the RCA radios say the use an RCA VS149 battery, but I cannot find one anywhere. Is there a replacement battery I could use? I’m dying to see if these radios work. Thanks for the help.

  27. Michael Jack Says:

    Hi John, great deal at the auction. Transistor radios don’t show up that often, especially in large lots of 12.
    There are some places that sell vintage batteries but I can’t think of the names off hand. A quick Google search should reveal them. I use an external power supply which can provide me all the voltages I need up to 22.5 volts (for the Regency TR-1 radios).

  28. Sean West Says:

    I just got a Zenith very small radio with an earphone and built-in speakers, as well. It takes two Z640 batteries. Does anyone know if these can still be bought? Great site, by the way. Sean

  29. Jay Young Says:

    I had a coral-colored Admiral 8 transistor AM coat pocket radio in early ’67. A couple of years later it got broken. I remember exactly what it looked like but not the model number. It took two AA batteries and was surprisingly powerful.

    The grillwork looked something like on this one,
    http://www.transistor.org/collection/admiral/admiral3.html
    and it had the side dial with the little window like that, too.
    The logo was at the top, on a screened aluminum panel (really nice). I believe it was chrome plated, not merely painted. I have looked for a similar radio everywhere. If you or any of your readers could help out I’d appreciate it. I’ll check back here periodically. Thank you.

    I realize there were dozens if not hundreds of Admiral radios made in that era, but if anyone could help me out, I’d deeply appreciate it.

  30. Jeff Lemon Says:

    Hello,

    I have a transistor radio that I have yet to see in any of the collections that I’ve viewed. I can only tell you that it appears to be 50s vintage, It is bright red and cream colored plastic and is labeled “Stat All Transistor Radio” It has a long wire antenna that plugs into the back and a hardwired earphone. No power or volume controls, and the tuning dial is simply numbered 0-4. It uses a single battery about the size of a double A only longer, no voltage marked. It is small, about 3x3x1 inch. I would be happy to send photos to anyone willing to help me identify, or otherwise learn about this piece. I’m thinking that this has to be one of the very earliest transistor models.

    Thanks,
    Jeff

  34. Rene Says:

    Hi,

    I have a pilco transistor radio and the model number is T-67GP and the ser. no. is 41488. I have been trying to find information on it, like how much it is worth. It still works and has a 9 volt battery in it. If you could help I would be greatful.
    Thank you, Rene

  35. Michael Jack Says:

    Hi Rene
    The Philco T-67GP was made by Toshiba for the Philco company. I believe it dates from about 1962 or so. It is not a particularly rare or hard to find radio thus it’s collector value is low. I bought one at a flea market for $5 but I have seen them sell on Ebay for around $20.
    It is an attractive little radio and since yours works I’d hang onto it and enjoy it.

    Regards
    Michael.

  36. Dave Says:

    I had, (I am pretty sure it was a GE) Transistor radio from 1962 or 1963. Small radio, AM only. Its box showed a bunch of sketch’s of people holding and listening to this radio. There was even a drawing of a small fish that was among the people. The case of the rado I believe was tan or white and it had a brass plated carry handle. I can’t seem to find this anywhere. If anyone can help me, I would greatly appreciate that. Thank you, Dave

    Brilliant!! I still get an endorphin rush thinking about these radios when I was a kid.

  42. Judy Berryhill Says:

    Loved the information, really brings back memories, wow! I still have my Channel Master 5TR in it’s leather cover, I used to hang it from the saddle horn on trail rides, what a life ! I wonder what it might be worth? Has 2 chipped areas but still gets AM stations even without the antenna. Thanks in advance for your comments.

    My grandfather just passed away and we’re finding all sorts of stuff as we’re going through his stuff. There was an old Arvin transistor radio in the closet – it’s red and there’s a large “6″ in the left hand corner, the dial starts with 55 and goes to 16 and there are 2 triangles on it – written above the middle of the dial are the letters “KC” and “CD” is written below it – does anyone know how to tell what model this is, or any other info about it?

    Thanks in advance, Jessi

    my dad has an All transistor Phillips radio which he bought in 1966. It is still working and serving him well. Unfotunately it has no FM bands and hence he nowadays cannot recieve the modern FM stations. Who can modify it for him?
    The attachment he has to it demand just that because replacement may not be an option the way he is.

  47. Mike barber Says:

    Does anyone know the name of the radio that we used to sneak into school in the 1960′s to listen to the world series in class. It was very small and it had to be clipped t0 your zipper to improve reception.

  49. Fabiana Says:

    Hi there, great article!!!

    I just purchased a ROSS Solid State transistor radio that is in what looks like a wooden credenza (small box) with books, made in Japan with a No.204 in it. I have found one similar on e-bay that is a cigarette holder. This one does have the triangles between the 6 and 7 and the 12 and 16. I am trying to date it, do you know anything about this type of radio? I really appreciate any info.

    like fabiana above – no. 49 – i too have a transistor radio that looks exactly like hers. has questions: 1) how do we know it’s a ROSS? 2) its date? 3) how does it work? it has two wires inside, a red and a black, which i assume hook up to a battery (8 volt? judging from the width of the hinge that holds it, but i’m not certain). a square box inside reads ‘mikawa,’ and the speaker appears to read ‘pine’

    cool little gadget! would like any relevant info.

    thanks.
