My problem is that when I try to mount it in its intended case Altoids tin the signal goes out and I get no sound. I also want to add an FM radio on it. How can I do it?? S Prakash Rao India Reply. This was my first ampmy first real circuit, and I did it with your video! How come the magnified signal is not clipped or badly distorted? I want to build a amplifier circuit for my new pair of watts speakers for perfect sound quality.

Alex on August 10, at My lm chip starte heating up once I had connected the cell — any idea why?!

Build a Great Sounding Audio Amplifier (with Bass Boost) from the LM386

Watching the video brought this to my attention. The LM is a type of operational amplifier Op-Amp. Could you tell me more about the theory here?

Is is possible to use more than 9v for example 12v with the two latter circuits just as is or is there anything that needs to be changed? It is asking me to write a programme. If your gain is set tothe range of volume is 0 to Is it a mistake, or should there be a total of three caps connecting the positive rail to ground, of which two caps are 0.

I need to break-in my new subs.

Volume control and gain control is also possible in this. Sanath on December 23, at 3: Hi Mark, Any kind of type for that cap. Hi, In one part of the circuit there are two decoupling caps connecting the positive rail to ground. What is the range of the …-1 chip ac voltage output?

I cut into an old pair of headphones for the 3. The pin 7 is used to connect a filtering capacitor 0. Hi, thanks for this post. If your voltage is lower than the minimum, the power output will be very low and the audio will probably distort.

So well documented and illustrated compared to other tutorials out there. Adinol on December 23, at 7: VAneza ybanez on November 25, at 6: The RC network with 0. Here are links to those articles:.

Build a Great Sounding Audio Amplifier (with Bass Boost) from the LM

I am at your mercy sir if any amount to be paid i am ready to pay I am your fan. Has someone an circuit for this?

I wanted to make a portable speaker out of an old speaker box I bought a couple of months ago and your circuit with bass boost was exactly what I needed. Circuit Basics on March 8, at 2: It is just the added bass control that I am having a challenge with…. So the datasgeet negative wires would connect to the negative rail, and the two positive wires would connect to the negative side of the uF capacitor.

Hi, Is this amplifier have enough power to fill a 4m x 4m room? Though its better if you do…… But if you search in Google with the name of the project you will find the script…… Ml386n copy and paste it. Hi, What type of capacitor is the blue pF?

I tried even there is clear voice. Arturs Spiridonovs on May 12, at
