Authentic Vintage Crystal Radio Circuit There are Crystal Radio kits and there are Crystal Radio kits, but this is truly the ultimate kit. The one thing all kits have in common including our own very popular Crystal Radio kit is that they include a modern diode as part of the radio circuit. Although this is great for radio performance and ease of assembly, it is not really authentic as they did not have modern Germanium diodes back when Crystal Radios were developed.. PURE GERMANIUM HOLDER Our new Ultimate Crystal Radio kit comes with an authentic 'Cat's Whisker' diode - which is what was used in the original Crystal Radio sets. A Cat's Whisker diode is the 'old time' version of a modern semiconductor diode. It consists of a crystal of absolutely pure Germanium in a small holder - with a spring loaded pin the Cat's Whisker to make electrical connection to it.. GENERAL CRYSTAL RADIO INFO The Crystal Radio has been a favorite for beginners as well as those advanced in electronics. It is the simplest of radios and was popular in the early days of radio. Crystal Radios receive the AM broadcast band. The amazing thing about them is they require no power source. You heard right - no batteries or power source of any kind. The Crystal Radio gets its power from the radio signal itself.. This is truly a Crystal Radio kit you'd be proud to own and have on display. Most Crystal Radio Kits you'll find are just plain ugly. They're either made from cardboard, a toilet paper roll and a nest of wires twisted about - not to mention being overpriced. If they have any wood or brass, it's usually a thin piece of cheap pine and flimsy brass clips. Not so with our kit Our kit is built around a hefty pre-drilled block of prime Red Oak.. The wood block is machined to hide the variable capacitor, allowing the base to sit flat. A minimum of wire and components is visible in the completed kit giving it a nice un-cluttered look. The kit's hardware is heavy, solid brass. Unlike kits you may find elsewhere, everything you need to assemble the kit is included. We include the adhesive, the stain, sandpaper, clear polyurethane and even the brush to give your completed radio a beautiful finish..
