Type 9 Diode Crystal Radio Transitron Germanium Point Contact Signal Glass Package

These genuine germanium diodes are a rare find. These historical diodes are amongst the first diodes produced by the Transitron Company around 1960. By their construction, these devices are the missing link on the line of evolution between a crystal detector and a real solid state diode. In essence, these devices are a scaled down, small size, enclosed, fixed point contact crystal detectors. They are useable for Small Signal commercial, industrial and military signal diode applications. These are real hard to find vintage collector's choice semiconductors. First come first serve supply is very limited.
