An LM386 based audio amplifier circuit

Post by April155 »

Hi, I'm trying to build a simple LM386-based audio amplifier circuit. I've attached a schematic of what I've got.

I've got a simple pair of earbuds plugged into the audio output end, and an FM radio plugged into the input end for testing purposes. I'm powering it off of a 9V battery.

What I hear through the earbuds is a "click" at regular intervals. Listening closely, I can tell the "click" is actually a very short snippet of audio from the FM radio. (Just a single note or even less.)

Again, I'm pretty new to this. Please don't hesitate to point out anything bone-headed I'm doing. All help is greatly appreciated!

Thanks in advance.
