As with the germanium diode, the reverse readings for germanium transistors will not be as good as for silicon transistors. A small level of current is allowable as this results from the presence of minority carriers in the germanium.
Homebrew Germanium PNP Transistor 20M SSB Transceiver ... In preparation for that project which ultimately used no Germanium PNP transistors, I did purchase a 100 piece box of Russian Germanium PNP UHF transistors. At the time I paid about 10 cents a piece for them. These transistors were weird looking and the in line pinouts were BCE.

PNP Germanium Transistor Buffer Basic Info and Mods The AC128 is a great sounding germanium transistor but if you buy many of them, there will be a large number left over that have too much basetoemitter leakage to be useful in a voltage amplifier circuit.

Silicon Versus Germanium Instantaneous Current and Voltage Waveforms Summary of Transistor Bias Circuits ... The basic purpose of transistor biasing is to keep the baseemitter junction properly forward

Jul 13, 2013· Any small signal transistor will work, it expects a PNP type but will work equally well if you use NPN and reverse the battery connections. At the time the circuit was designed, PNP germanium transistors were easier to find the NPN ones.
These are PNP TungSol germanium transistors. According to the date code (6326) these transistors were made back in 1963, long before I was born. According to the date code (6326) these transistors were made back in 1963, long before I was born.
