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.
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.
Audio Signal Tracer Schematic - Engineering Projects

Working of the Audio Signal Tracer Schematic. Talking about the process of how this device works. Initially, we feed an audio signal which is also called a test signal into the tracer circuit at points CON1/CON2 from multiple points of a circuit to be tested. The point up to which the signal is clearly heard without any distortion is working fine.
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 ...
Basics of Signal Tracing - Rob's Radio-Active
https://www.robsradioactive.com/basics-of-signal-tracing
Like signal tracing, the results will be relative, and it is not a bad idea to get some hands-on practice with a known good receiver or amplifier of similar type in order to know what is a normal response. Most signal generators put out a fairly feeble audio signal, and not all of them can drive a speaker directly.

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 ...

Description. A high gain amplifier circuit that can be operated from a battery pack of 6 or 9 volt battery pack is shown here.The IC1 uA 741 is wired as a high gain non-inverting amplifier and its output is amplified by a pair of complementary transistors (Q1 & Q2) to drive the speaker.The negative feedback from the common emitter junction of ...
