Hi,
I am posting in this forum after few years gap. I don't know this post belongs to this group or not. If I am posting in a wrong place, my request to moderator please move this post to appropriate section.
I am willing to build a pet repellant, I need a ultrasonic amplifier fir that device. Please suggest an amplifier.
Frequency : 15KHz to 40KHz
Output : 10W max
Impedance :?? as you suggest
Power supply : 12-0V preferred
Input : 2V PP (Sine or Square wave)
Any other suggestion on this project also welcome.

No need for separate oscillator + amplifier, just build a power oscillator which outputs a squarewave at the frequency you want.
No need to reinvent the wheel either, there´s lots of such projcts all over the Net.
Your problem will be the speaker, suggest Piezo tweeters which are efficient, inxepensive, and reach easily up to 30 kHz which is perfect for this application.
That said, ultrasonic repellents are not *that* efficient , not all pests will run away.
Rats specially either are resistant or develop tolerance quickly.
