Piezo transducers have an impedance from about 20,000 to as high as 200,000 ohms. A simple step down transformer can work for the lower impedance transducers...for the higher impedance ones, you probably want to go directly to an FET amplifier.

What application is this for? Is this for audio frequencies or superaudio?
