Re your 80 watt driver. My circuits involve low power units and are not suitable for your application. If you know the resonant frequency of your transducer you could use an audio amplifier of, say, 100 watts and feed its input with a sine wave of the required frequency. Watch out for output stage heatsinking, as continuous duty such as the above can result in rather more than usual heating. If you want any info on determining the resonance let me know and I can provide some details.
