Crystal Radio ~ Germanium Diode ~ 1950's Japan Import ~ NIB

1950’s Japanese Import Crystal Radio Set Warehouse Find ~ Unopened in Original Box Not a toy. This small (3 ¼ by 2 ¼ by 1 inch) radio needs no batteries. It is a “Crystal Radio Set” and works on a Germanium Crystal Diode. It actually pulls its own power out of the air from the AM radio waves to operate. The 1950’s Japanese crystal radios have a collectors following of their own because they are so unique. Rarely do we find several dozens of one type “Still in their Original, Unopened, Dime Store Box”. These sat undisturbed in a warehouse for well over a half century. We found several styles of Japan Crystal Radios in a warehouse find. This one has the strongest reception and loudest earplug. It is simple to operate. It has an ear plug for listening. It also has a “Ground” clip attachment. Just clip onto a good electrical ground to attract the AM radio waves out of the sky. A gas pipe, water pipe, etc. Anything that has a metal rod going deep into the ground will do. It is designed to pick up any AM radio station that is nearby, and some of the powerful AM Stations it can pick up for several miles. Weak or distant stations sometimes won’t come in well. However a longer antenna wire is all that is needed! It is simple to add an auxiliary antenna. NO BATTERY OR ELECTRICITY EVER NEEDED. This clever little radio comes with complete instructions. Because it works on the minute power it gets from the radio air waves, it will not work in a metal building. If you want to listen to farther stations, or live in a metal building, you can connect the radio to an antenna extension. A thorough explanation of how it works, and connecting it up, can be read on the bottom 3 paragraphs of the instruction sheet that is included with it. The last 2 photos are of the inside of the radio. It is for the technical oriented collectors. There is no guarantee that you live close enough to an AM broadcasting station to receive it loudly. These were recommended in the early 1950’s for bomb shelters because they need no electricity. In the early 1950’s, they understood this technology well enough to make a reliable unit. Hard plastics were just starting to be used in products. Most older Japanese Crystal radios have minute “contact marks’ where the rubber covered earphone wire came into contact with the incompatible hard plastic case. This radio has one only about an inch or so on the back, from where the rubber earphone wire comes out of the back, and ran straight down out of the baggie. This does not affect the operation. The insignificant marks are on the back and can be seen clearly in the last photo. They packaged the radio in a clear baggie and coiled the earplug wires at the bottom of the box, so the hard plastic radio does not come into contact with them. Clever 1950’s Japanese Product! You get the next one, AS IS , Right from the Large Wholesale Box, just like the Dime Store stocked them in the 1950’s! We have a small AM Transmitter nearby, and test every Crystal Radio before we ship it, and guarantee it to work. You must live close enough to an AM transmission tower and provide a good solid ground point to clip to, usually a water pipe works well, to receive a strong signal. We have several styles. Watch our eBay Store as we add photos and descriptions of the other models. We ship by First Class, US Postal We received this feedback on the radio recently; Just got this Xtal Radio. I connected it up to my 100ft SW antenna with Balun. What a great little performer. Got a bunch of stations on it around 4:05. You get better performance late at night I find. I have a few of these and also Rocket Radios and this is one of the best. I’m a Ham Amateur. Thanks for the excellent packaging and notes. 5 Stars. #7390 Price . . . . $69.85
