Not all speakers/radios/walkmans have amps... some are non-powered which means that they don't have a built in amps and need an external amp. Please post the model number for the device you are looking for. :)

Making one would be pretty hard if you don't want to go buy components from a store... but if you have some old computer speakers laying around, they usually have some decent amps in there, or basically any powered speaker would have one.

Maybe could you post a link to the project you are trying to build? That might help me give you more suggestions. :)

Thanks for your time thegeeke

Well can you tell me how to take the amp out of my speakers since I have some but I hope I can power them with a 9volt battery

https://www.instructables.com/id/Make-a-Simple-Audio-Amplifier/

I want to find an amp like this without getting mixed up with the boards capacitors etc

As I said before I'm trying to make a tinny amp or an altoids amp for a project involving conversion of electricity into sound

https://www.instructables.com/id/Altoids-Amp/
This is want I want to make but the reviews aren't too good. Also there aren't many pics.

P.S. Is it possible to get an amp from a telephone

Well, yes, there is a very small amp in the walkman he was using, but it's just meant for powering headphones, not speakers. (I assume you are trying to power speakers?)

Same thing with a telephone, it's basically just a amp for a small speaker or headphone. It will not power any speakers that you can hear.

The easiest way that I can think of to find an amp would be to take apart a small powered speaker and rob the amp from that. Then just connect an input the the input wires for that amp, and then connect whatever you are trying to power to the output wires. You should be able to get a project enclosure for it if it doesn't fit into a Altoids box. (Depending on the size of the amp you are stealing it probably will not fit into a Altoids box.)

Good luck!

Oh... forgot to tell you about powering with a 9 volt. Most powered speakers are powered via DC, so there is either a AC-DC adapter that plugs into the wall, or there is a AC-DC conversion circuit in the speaker. Just plug the 9 volt past the conversion, and if you're lucky it should actually power it. Worst case in senerio, you don't have full power. In that case you could try hooking two 9 volts in series. :)
