So the input signal will get oversteered fairly quick.

We just published a tutorial on the TDA which has an output power of around 7 to 12 Watts: Is there any cheap and good quality stereo amplifier for headphones? What are the voltage of the electrolytic and wattage of reaistors Reply.

Hi, What type of capacitor is the blue pF? Makes a fantastic headphone amplifier for our drummer as well.

Mohit r on July 10, at 8: GeRT on September 24, at I wanted to know if there are stripboard plans for this or would I literally just transfer the breadboard design to stripboard?

Great little article, thanks. I am having a problem with the extended bass circuit. Looks like there datasheft be a typo somewhere as each side is shown connected to ground??

Thanks to circuit basics. I am at your mercy sir if any amount to be paid i am ready to pay I am your fan. Thank you for sharing! I used the LMN-1, but the setup would be the same for each model, the main difference being the power output. Great circuit LM with bass boost. Do i spend eatasheet for that. I used a 9V battery for the power supply and it works great, but you can go down to 4V or up to 12V.

Randy on September 19, at 6: Can I use k pot????? Dear sir Resenltly i purchased the Arduino Duo board dagasheet INR but when i conected to my laptop asked me to download soft ware and i down loaded. Is this value critical? Some how I miss old dos, in some ways it was less complicated back then. For that I think you would be better of building a dedicated subwoofer amplifier, or using a tone control circuit.

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

Excellent tutorial I managed to make the first two today and will work on the final versions next. NOME on December 30, at 1: Just wondering will this circuit still work if I increased the number of speaker to speakers?


The labels are correct, but the color coding is swapped. Pulkit Sharma on July 4, at 6: Please answer it Reply. Dan L on November 24, at 1: After doing so i decided to make the other channel stereo soundand replicated the circuit on the other side of the board.

Using this for my school project. As a tester for a particular system. I just want to ask if this is an active or passive loudspeaker? So i just tried building the second circuit diagram and the sound is just awful I did build it on a bread board how much better can I expect it if I build it on vero boar with short wires and such? Shall I get good quality sound for laptop? The minimum voltage rating is 4V, so it might not work.

Hi Sipan, to connect the amp to my iPhone, I cut into an old pair of headphones:
