    Hello everyone. Im looking into making my own cable tracer using following description.

    I would like to add an 3.5 mm audio jack. And for the probe i was going to use telescopic pole off an old radio.

    I wonder if someone could help me add 3.5 mm jack. Also how did the creator come up with various values for the resistor etc. In addition to that, how does this audio amplifier work. In the fox generator i can see flip - flop circuit , with what i think is Darwin pair transistors.Little confusing. As for hound there audio amplifier , FET?????. All bit strange. So love to know how it all works.
