PNP: Silicon replacement is 2N2907 or 2N3906. (Or: device with beta= 200). NPN: Silicon replacement is 2N2222 or 2N3904. (Or: device with beta= 200). You may use other devices. But in 1-resistor bias circuits, you must adjust the base resistor Rb value for correct bias.

Does it matter if I replace germanium transistors with

Silicon transistors started replacing germanium but I guess not quick enough for that article. As mentioned, you want to use the PNP version like a 2n3907. And keep in mind that while they work in similar manners, germanium diodes have a forward voltage of 0.2~0.4 volts on average, while silicon will have 0.6 to 0.8 volts.

The amp in the jukebox I'm restoring has 2 germanium transistors on the front end. One tests ok on my cheap Chinese component tester, but the other tests bad. I couldn't find a 2N591 model but did find a generic Ge PNP small signal transistor model. It seems to work fine in the original circuit. This is the frequency response I got for the

TO7 and TO45 are the same case. TO45 is what replacement transistors were made to. For PNP TO45, try the SK3006- I know of no other TO45 cased replacement transistors. ECG and NTE replaced these with the ECG/NTE160, a 4-legged TO72 cased transistor. It's also what most distributors will sell you. SK3006 transistors are still around, albeit scarce.

What is a Germanium Transistor? (with picture)

Sep 23, 2020· A germanium transistor is a variation on a standard transistor built on the element silicon, where, instead, a silicon-silicon-germanium 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.
