S Scubasteve New Member Apr 28, 2003 #2 What you are describing is a radio reciever, not a power amplifier. If you have an audio source, you can build a small amplifier that will do what you need. There are too many instances of amplifiers and circuits to describe that will work. here is a page on audio amps.. https://ampdesigns.tripod.com/Design_of_power_amp.html Steve
