Germanium Transistors

1 OC139 NPN Germanium transistor, new old stock, black glass body, made by Philips. Use them to make a fuzz face with negative ground so you can run it off a standard 9v power supply (like the Boss PSA or 1Spot). Gain range is 50110. These are PRETESTED so …

What Germanium PNP transistor do I use? | Electronics Forums

Mar 17, 2007· Germanium transistors were pretty much obsoleted forty years ago, by silicon transistors. There is a far better range of silicon transistors, and generally they have far better specs than germanium transistors. The only reason you''d use a germanium transistor at this time is if there was a specific reason for using germanium. There are still some

What is a Germanium Transistor? (with picture)

Jan 30, 2019· A germanium transistor is a variation on a standard transistor built on the element silicon, where, instead, a siliconsilicongermanium alloy is commonly used to increase transmission speed of electrical signals. Individual electrical component speed adds up as an aggregate, and, therefore, a germanium transistor array can significantly increase the processing speed of a circuit.
