Four Pieces: Crystal Radio Detector Diode Germanium Point Contact Type ~ Quantity 4 Pieces with each Buy-It-Now ~
Build a crystal radio receiver using a point contact diode.
These are vintage point contact germanium diodes made by ITT. They work great in crystal radio receivers. The point contact is clearly visible through the glass (use a microscope or magnifying glass to s...ee).
These are high quality crystal diodes with a gold wire making the contact. They are rare - point contact germanium diodes by ITT are no longer made. Newer germanium diodes are typically not made with a gold wire point contact.
Most standard diodes (including common silicon types) do not work well as a crystal detector. The best are point contact germanium with a low forward voltage. These diodes are guaranteed to work as crystal radio detectors. The part number on the diode is: ITT 1N270
