THE TRANSISTOR AS A VOLTAGE AMPLIFIER TPG Internet

Base voltage V be as a function of base current I b for a germanium transistor To illustrate the variation of AC base resistance with variation in base current (I b = I e / H fe ), figure 2 is shown. Observe how the slope of the curves (and hence the value of R b ) decreases as the base current is increased....

Flasher Circuits Technical Library

However, it relies on leakage in the base of the PNP germanium transistor and only some will work; be prepared to try a few. If you add a 100k resistor from the base to the collector of the PNP, the circuit will work with most germanium transistors and will work down to 1 VDC!...
