1950’s Japanese Import ~ Germanium Diode

Crystal Radio Set

Warehouse Find ~ Unopened in Original Box

This small (2 by 2 by 1 inch) radio needs no batteries. It is a “Crystal Radio Set” and works on a Germanium diode crystal. 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 the Original, Unopened, Dime Store Box”.

It is simple to operate. It has an ear plug for listening. It also has a “Ground” clip attachment. This clip must be clipped 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. The antenna is one of the wires that goes to the earplug. It can pick up any AM radio station that is nearby, and some of the powerful AM Stations it can pick up for miles. Because the earplug antenna wire is only a few feet long, weak or distant stations 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 in a vinyl carrying case and comes with complete instructions. Because it works on minute power it gets from the radio waves, it won’t pick up long distant or low power stations well, and will not work in a metal building. If you want to listen to farther stations, or live in a metal building, there is a place on the radio to connect an antenna extension. I don’t live near an AM Station, so I added an antenna extension, a wire about 3 feet long with a clip on it. I stretched some thin wire between two trees, clipped my antenna extension to it and received several distant radio stations.


There is no guarantee that you live close enough to an AM station to receive it loudly. These were recommended in the early 1960’s for bomb shelters because they need no electricity. In the early 1950’s, they were just starting to understand plastics better. The earphone wires are rubber coated, the radio case is hard plastic, and the carrying case is vinyl.


It has been wrapped tight in its original box for over 65 years. You get the next one, AS IS, Right from the Large Wholesale Box. Just Like the Dime Store Stocked Them in the 1950’s! Due to its age, and different plastic materials used, and never being opened, some “negligible small markings” where the earplug wire was wrapped tight, etc. might be visible. It is so small and light, We ship it FREE!
