Signal tracer is a simple audio amplifier with high impedance input used to "hear" a signal in a circuit; ther's a probe (with a switch for "Radio freq." or "Audio Freq.") to insert in the circuit; signal on the probe is amplified by the audio amplifier IC and then you can monitor and hear it in the speaker or in earphones.
