@paulrickards try with a multimeter in DC, you should have less than 100mV across the loudspeaker terminals with no sound. Alternatively you can check if the loudspeaker moves and stays in a position different from rest when the circuit is switched on (no sound).

A while back I bought two of those Maclocks with the intention of modding one into a tiny Mac.@paulrickards the power consumption looks quite high. Is there a DC component that is fed to the loudspeakers, by chance?
