Alex on August 10, at If I were you I would rebuild the entire circuit with all the components replaced including the chip and the speaker. Is it normal or it is feeding to much power to the speaker or something?

I tested it and it worked! Peter on October 4, at You pm386n the previous comment. I added a bunch of extra capacitors to reduce the noise, and I added a bass boost control as well to make it sound even better. Harold on May 26, at Google classified a amplifier and use one of the tip as transistor.

Kev on April 22, at 1: Thanks again, great article and video, too. Is this value critical?

WillW on December 18, at 6: Shafin on October 1, at 1: Siraaj on April 14, at 9: Please send me the schematic diagram. Can this circuit be used to increase an audiot input from ratasheet Hz up to 50 KHz? Shall I get good quality sound for laptop? Jefferson Yagdulas on March 3, at 3: Class a amps have more potential in terms of audio quality but Are harder to design due to having to properly bias the transistor.

Sanath on December 23, at 3: It currently has alot of hum on the line when its in use. It should be between pin 3 and GND, not pin 2. Cody on September 21, at 3: The only circuit diagrams I have are already included in datashheet article. I tried both options while building this. Thempleton Aart on October 12, at 4: I cut into an old pair of headphones for the 3. How capacitance and resistance value is selected for speakers Reply.

Operational amplifiers have a basic task. What is the load of the circuit? If you go too large though the bass will get really muddy sounding. Check out this article for more info: The circuit operates at 9V, so any capacitor voltage rating above about 16V will work fine.

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

Roy Hammond on July 17, at 6: AlharbiM on October 29, at 8: I recently discovered this as well… The grounds for the input, output and power should run separately from the ground pin of the chip to reduce interference. Though its better if you do…… But if you search in Google with the name of the project you will find the script…… Just copy and paste it. There should be three caps connecting the positive rail to ground. I have 2 questions….

Check out this article, How to Hack a Headphone Jack to see how to do this with some common types of headphones. Any suggestions on whether the audio signal can just datqsheet parallel or would I need separate audio signals?

Make it a goal to keep the input ground separate from other ground paths as much as possible. Here are links to those articles:.

This was just what I was looking for. I need to break-in my new subs. Sanjeev Chauhan on February 24, at
