    Hi everyone,

    I’ve experimented a little with this circuit and made a version with the legacy modules using germanium transistors.

    The circuit needed little adaption since the those transistors have a build in resistor which changes the base current.

    I’ve also added a 250K potentiometer so you can fine adjust the trip set point of the transistor.

    Here’s the diagram :
