            I have about a dozen of these great little amplifier-speakers where I teach at the university. We have used them for years in a neuroscience laboratory course. They are terrific for setting up simple electrophysiology rigs.

                I bought this to use as an external speaker for my CZ 6a Fisher metal detector. It meets all my expectations and more. It has a great sound and hooks up within seconds. Just add a 9 volt battery and plug it in..its that simple. Great performance. I will buy another one for my backup
                detector.

                    I've had mine for so long that it's got the "Archer" brand on it! I use it to play a "click" track (metronome track) from my keyboard sequencer, feeding it into an earphone. I have many music sequences -- brass, strings, timpani, etc. -- which I play along with on a pipe organ and the click track keeps everything together.

                      Comments about RadioShack® Mini Audio Amplifier:

                      Radio Shack does itself a disservice by calling this a "Mini Audio Amplifier" on the website rather than a "Mini Amplifier / Speaker" as the product's instruction sheet says; it is impossible to find by searching for "speaker".

                      Nevertheless, this small classic of many years is just as good as ever.

                      I love my Garmin nuvi GPS but the audio output is just too low for my hearing. In my car, I have a small 12V amplifier and an external speaker which boosts the output enough to be hearable even with the windows open.

                      I use the RS Mini Amplifier / Speaker with my Garmin unit when traveling; because it is self-powered (by an internal 9V battery), it does not require another car "cigarette lighter" power plug.

                      It is inexpensive, compact, rugged, and has its own power switch / volume control. HIghly recommended!

                          I'm a TV news photographer. We use this almost everyday to boost audio level from a cell phone for IFB during live shots. The cell audio with a Telex IFB is simply too low, especially in a noisy environment. We cable from the cell to the amp, and plug an earpiece into the amp and get great audio level. The reporter can adjust the level as we're setting up. I added a switch so the speaker can be turned on or off without unplugging the earpiece. Saved our butts more times than I can count. I have a 2nd one in the live truck, as a back-up, but it's never been out of the box. Also added a belt clip from an old handheld scanner that works fine, so long as you're gentle with it. Would love to see a smaller model of this amp without the speaker. The battery will usually last me about a week if the reporter remembers to cut it off after their liveshot.

                          I've got a pair of these that I've used in our business for 22 years straight! They work as a preamp for a sound system input. They also work great for troubleshooting an audio system. They can drive speakers with a 25V or 70V transformer too! They are useful for Science Fair projects to boost the audio from your crystal radio headphone to a level that everybody can hear. 9 Volt battery last a reasonable amount of time - not forever, but good enough for me. This is one item every ham should have in their tool box to test microphones, etc. This is truly one item that Radio Shack has done perfect, and I hope that they will continue to sell it another 25 years! A+ rating from this engineer.
