Substituting Silicon transistors for Germanium

Aug 07, 2017There are some problems that come up though, but then i read that there was research being done on hybrid transistors that are part germanium and part silicon. If they are on the market by now maybe you could check into that. Otherwise perhaps a germanium to start the circuit and then bootstrap to keep the circuit going.

What Germanium PNP transistor do I use?

Mar 17, 2007Germanium 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

121-352 Germanium Transistor. The 121-352 is a PNP germanium transistor used in the intermediate frequency (IF) stages. This is a small-signal high frequency transistor. You can usually swap the three from the IF with the three for the AM section and the radio still works. AF116 also works in stage one and stage three of the IF circuits.
