You get a constant hum if you do and I have not yet found a way to fix this.

Can this circuit be used to increase an audiot input from a Hz up to 50 KHz? Roy Hammond on July 17, at 6: Mine was working right away and really surprised at the clarity. I built a stereo amp a while ago and fixed me some nice pc speakers.

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 lm38n6-1 and such?

I used the LMN-1, but the setup would be the same for each model, the main difference being the power output.

Hi I was wondering about this amp are those mono amps? Micheal dafasheet August 1, at 9: Philip Samsa on April 28, at 6: Datasheeet, um this really is one of the best diagram i was just wandering that is this an 8 ohm speaker used? Would you please help?

DungFung on July 29, at 6: Sipan Hadji on February 13, at 9: Will it work with a guitar with two humbuckers? I am interested in recycling my old notebook speakers 2watts each to make a usb driven amplifier with 2.

The reason is that there is always an outer shield, with film caps. They work just as well and are better than a handfull of jumper wires… Reply. Velyx on December 28, at 3: Adinol on December 23, at 7: Great little article, thanks.

Murat on March 8, at 2: But yet I have a few questions D: Email me new tutorials and very occasional promotional stuff: And what are the voltages of capacitor that you used?

Makes a fantastic headphone amplifier datashee our drummer as well. I wanted to know if there are stripboard plans for this or would I literally just transfer the breadboard design to stripboard? I use a 12V supply and a pot meter to attenuate the input signal to something below 0.

Cant seem to figure out what is wrong cos i followed the diagram exactly without success Reply.

If your gain is set tothe range of volume is 0 to You can connect two speakers lm386j-1 parallel. No you dont need to learn c language….

Try using the tda Akmal on December 13, at 9: Steven Scheerlinck on November 25, at 7: Jesyca JC on October 24, at 8: Decoupling means disconnecting two electronic circuit stages against cc from each other. A Good Job of explaining this. It currently has alot of hum on the line when its in use.

The only diagrams I have are already included in the article.
