My tester trips at about 29 ohms. The output (pin 13) of U1D goes low when the probes see continuity (29 ohms or less in my example). The AUDIO section is an oscillator centered around U1A, followed by an ‘amplifier’ Q3, which is really just an on/off switch pulling current through the speaker. The oscillator consists of U1A, C2, and R7-11.
