Signal Tracer For Audio Fault Finding - sound-au.com
https://www.sound-au.com/project164.htm
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.

Signal Tracer Project - Rob's Radio-Active
https://www.robsradioactive.com/signal-tracer-project.html
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. Double throw switches in both cases connect the signal where desired and disconnect from previous amplifier stages to avoid ...

The LM386 Audio signal tracer RF Probe Amplifier circuit diagram for maintaining preamplifier, power amplifiers and even RF devices. As a probe of audio signal and RF, can make maintenance of equipment such as amplifiers, preamplifier, radios, car audio, transmitters, recorders, televisions and more. The basic operation is to follow the audio signal to a point …
Audio Signal Tracer Schematic - Engineering Projects
https://bestengineeringprojects.com/audio-signal-tracer-schematic/
The complete circuit of the project; ’Audio Signal Tracer Schematic’ is given in fig. 1. The circuit uses two ICs; LM358 (IC1) and TDA2822M (IC2) as its chief component. IC1 consists of two operational amplifiers which get operated from a single power source with a wide voltage range from 3V to 32V.

Dual audio signal tracer circuit Fig. 1: Circuit diagram of the dual audio signal tracer. Fig. 1 shows the circuit diagram of the dual audio signal tracer. It is built around LM358 (IC1) and TDA2822M (IC2). LM358 has two independent, high-gain, internal-frequency-compensated operational amplifiers, which are designed specifically to operate from a single …
Signal Tracing - ChildhoodRadio
https://childhoodradio.com/signal-tracing/
Signal tracers are simply audio amplifiers and speakers with test leads that let you locate and hear signals in the various radio stages. They also have a diode used to detect and convert RF signals from the "front end" and IF sections of the set into audio that you can hear through the tracer's speaker.

Here is the schematic diagram of the signal injector/tracer circuit: Tracing an audio signal can be done using an audio amplifier, but using a handheld instrument would be more convenient, since you can make such instrument with special probes. As the opposite of tracing, injecting an audio signal is important too. Injecting an audio signal means connecting a certain point at your …
Audio Signal Injector/Tracer – Electronic Circuit Diagram
https://freecircuitdiagram.com/898-audio-signal-injectortracer/
This testing instrument provide two alternate fuction: signal injector and signal tracer. This audio signal tracer/injector is very helpful in trouble shooting audio circuits, when you need to test a circuit by injecting a signal and observe the output (by watching the oscilloscope or by hearing the loudspeaker for example), or by tracing some points inside the circuit when an audio signal …
