This signal tracing circuit can also be implemented as a dual-audio amplifier as well as a low-power stereo amplifier. For a 4-ohm speaker with 9V power supply, this circuit offers an output power of 1W.

Signal Tracer For Audio Fault Finding - sound-au.com

Introduction Signal tracing is a way to diagnose where a fault lies in an audio system. It's nowhere near as good as an oscilloscope, but it's a cheap alternative that can be useful in many cases. The idea is that you apply a signal to the input of whatever isn't working, and trace the signal through the circuit until the audio disappears.

The signal tracer works in much the same way with audio probe, except that an audio signal requires no detection, and usually does not require as much amplification, so it is fed to the volume potentiometer to the LM386.

An audio signal tracer is a simple device used to troubleshoot for audio signals in radio and other electronic circuitry. The device is a battery-powered stereo amplifier with two loudspeakers, packaged into a small handheld unit with test probes. An optional diode detector can be incorporated for the detection of amplitude-modulated signals.

Pro: affordable, works well (best in audio circuits) Cons: As is, it has limited use in tube circuits (max. contact voltage is 100v, but can be modified with three higher voltage capacitors to allow use on higher voltages). The signal generator produces a ~1khz sine wave, lacking the harmonics needed for work in the high frequency sections of ...
