    Hello Michael and Günther,

    Today I found some time to finish the amplifier modules and make them work as intended.

    I have also the “wired” versions and this is an easy way to fix these.

    I drilled an extra hole for the emitter of the 2nd transistor and used a different wiring.

    I also inserted a 100nF capacitor at the input and removed wrong 10K resistor.

    I also made a 2nd amplifier module with 100µF capacitor inside for easy setup.

    Many greetings

     

    Here are some pictures :
