Hello, I've try to buy a AM/FM kit in electronic store but it produce low sound. I try to used the amplifier in our house and its has lot of noise in AM station but when i used the amplifier that i create, it produce low sound.

I already test it in my laptop and it produce good quality of sound and loud.





Thanks

 

Hello,

Is there a datasheet of the used AM/FM receiver chip?
There are some scribbles on the shown schematic, making the type of chip unclear.

The LM386N will give max 1.25 Watts @ 10% distortion.
How many watts do you want to make?
How will all be powered?

I don't know how it is in your part of the world but here AM is pretty much useless because of all the interference it is subject to.
Does the FM part of the radio work OK?

the fm is okey but low sound

i really dont know what chip is it, i try to research but i cant find it, maybe they dont want us to know what is it.

i think i use a speaker of 8 ohms in 1 amp.

the receiver has a supply of 12v and the amplifier 9v.

The way your LM386 is set up it has a gain of 20. You can increase that up to 200 by connecting a 10uF capacitor between pins 1 and 8. You can also set gains in between 20 and 200 by putting a resistor in series with the capacitor.

 

Hello,

Perhaps a board with a PAM8610 might be something for you:

Hello,

It looks like that EBAY is blocked in your country.
Can you look at amazon?
