I need to amplify the sound from a 9 volt dc audible probe circuit.
The probe provides a very low musical melody sound that cannot be
heard.
However, another audible probe circuit that only beeps, is audible.
At the musical probe output, the voltage is very low, around micro
volts.
The audible probe outputs slightly higher voltage.
