Default Re: Germanium transistor replacement

In the majority of cases there is sufficient tolerance within the circuit and transistors themselves to operate without bias changes. Early Ge transistors had a wide spread of characteristics, and the circuits designed for them had to work with all of them.

The big exception is the audio output stage, which almost always requires circuit changes to work properly with silicon.
