Post ultrasound amplifier Reply with quote
Hello,
I would like to build an ultrasound 50W power amplifier to drive an ultrasonic speaker. Could you give me some ideas especially concerning the output filters?

My speaker has a resistance of ~2 Ohms and a capacitance of 160 nF it resonnates at 38kHz.

Thanks

Hi! Just wondering where you got your ultrasonic speaker from? Sorry I can't help you with your question... I know that ATS sells speaker/amp combos... you could ask them. Good luck!
