I used one of these to power a small speaker attached to a home made signal tracing probe.

The LM386N-1 of this amplifier is the low-voltage version of the LM386, recommended for 12 volt DC maximum power supply. At that voltage the rated output is ONE watt, and the distortion is horrible at 10%.It is a cute little amplifier but only capable of a few hundred milliwatts of clean audio.

This amplifier appears to be configured to operate at maximum voltage gain, which according to the LM386 data sheet, is 200. I was having a problem with the input picking up hum and noise, which I solved by reducing the gain to its default value of 20. Max gain is set by connecting a capacitor between pins 1 and 8, and the default gain is set by leaving those two pins unconnected. The IC is not surface-mount but through-hole, so I carefully cut pin 1 on the IC, leaving an air gap. That reduced the voltage gain to 20, solving the noise problem.

While I prefer the asceticism of listening to a crystal radio with just an earpiece driven by the circuit, my hearing isn’t what it once was. This marvelous little amplifier is just the thing to drive a speaker using the crystal set’s output. Perfect in this application.

I have a very old AC Voltmeter that has an audio amplifier module connected to it. It is used for audio signal tracing and trouble shooting. The amplifier module stopped working and I replaced it with one of these. It is running from a 9-volt battery and has a small speaker connected to it. This piece of test equipment is used intermittently and this module is great for that application. Price is great!

First of all, it's a nice little amp for the price. However many people including myself have been having trouble with the input jack. I found it to be a design flaw. The jack is TRS(tip ring sleeve) when I was expecting TS(tip sleeve). The jack and the board are wired backwards so that only the ring and the sleeve are utilized, but not the tip. Easy fix: De-solder the jack and re-solder it on the other side of the board, and now you have the tip and the sleeve for use with a mono plug. Worked like a charm!

First of all, let me say that the LM386 won’t produce anywhere near 10 watts. Under the right circumstances, you’ll get about 700mw, before getting into bad distortion. This isn’t a complaint, but more to let people know what to expect, as opposed to the claimed 10 watts of output power.I finished restoring a 1923 one tube regenerative radio. I have headphones for it, but what fun is that? It’s hard to show off, when only one person can hear it, at once. I made a small speaker to match the cabinet of the radio, and placed this amp inside of it. It will run, nearly forever, on a 9V battery. (Also installed into the speaker cabinet.) It won’t shake the walls of your house, but it’s loud enough for a room full of people to hear it.These are just some good, all-around utility amplifiers. Whether you’re a professional, or a hobbyist, you’ll find many uses for these.

Not 10 Watts but typical LM386 @ .5 W or (500 mw) but still excellent value, well made and easy to mount using nut on volume control. Have a nice LED power light on boardand easy connect screw clamp terminals for the power & 8 ohm speaker. A standard mini phone jack for capacitive input circuit. No schematic or directions but the board is well marked and the 386 circuit is pretty standard and available on the Internet including some options for gain and tone control. This is a basic amplifier. Both worked fine for my small projects on 9 Volts and I remoted the input and volume controls in another project. Again, good value-Works!
