  • Does it matter if I replace germanium transistors with

    The main difference between germanium and silicon transistors in switching circuits, be they either PNP or NPN transistors is that VBE for small germanium is about 03 volts whilst those of silicon are about 07 volts Also germanium are more sensitive to heat than silicon and can end up in thermal runaway and destroy themselv.

    Can I choose a different transistor type for a Twin Bender? No  What is special about powering Germanium fuzz pedals? The correct type of Germanium transistor used in many fuzz pedals are special in that they require opposite polarity power You cannot power two pedals with different polarities from the same power supply.

  • Substituting silicon transistors for germanium?

    I have an old power supply that uses a germainum 2N297A TO-3 as a pass transistor When I looked up the price of replacing the 2N297A I was a bit surprised at how high they are! I realize that prices go up when parts are no longer made or rare, but is there something special about germainum transistors? I looked at several typ.

    And as a consequence of that, most early germanium semiconductors were replaced with silicon These were primarily transistors and diod However, germanium diodes have the advantage of an intrinsically low forward voltage drop, typically 03 volts; this low forward voltage drop results in a low power loss and more efficient diode, making it superior in many ways to the silicon diode.
