hi friends :) I've built an audio amp ( I chose two projects , volume controller and power amp) and they work together pretty good but when I increase the volume (almost max) I hear very bad sound (distorsion). I've used many loudspeakers from the smallest to the largest but it is the same distorsion all the time. ??? :( So what do you think the problem is? I've heard about "limitation of current" ... ??? here are the projects i've built: http://www.electronics-lab.com/projects/audio/039/index.html http://www.electronics-lab.com/projects/audio/006/index.html Please can you suggest something to do... ;D

thanks :)

Hi What kind of capacitors ( at the inputs 2&19 and 6&15 ) have to be used in this circuit: http://www.electronics-lab.com/projects/audio/039/index.html Are there for eg. ceramic, tantal ...?? ??? Help please ;D

Thank you so much Audioguru for the explanation ;D

Hi Audioguru :) I used 15V DC , 6 ohms impedance and 12 cm diameter (2-way speakers). Do you think 4 ohms impedace will do better? And what is the typical voltage supply do you think? I believe you Theory Expert ;D. Best Wishes Mukhalled ;)

Hi I've built preamp + amp : http://www.electronics-lab.com/projects/audio/039/index.html http://www.electronics-lab.com/projects/audio/006/index.html I've coupled them together and they work, but I get very high distortion when I increase the volume (when the bass is full ). My question is : what can be the cause? Should I use larger speakers? Thank you all for supporting me ;D

Hi Audioguru and thank you so much for helping me ;D I'll build it ;) Best wishes

Hi again What do you think about this curcuit:- http://www.electronics-lab.com/projects/audio/039/index.html Can I couple it with this amp: http://www.electronics-lab.com/projects/audio/006/index.html to control the volume, bass, treble and balance? :) I was so happy when I hade built this amp and I will be happier to build the control curcuit for it. ;D Can anyone help me please

Hi Kevin your curcuit is really interesting and seems good actually ;). Can you find a simple solution to my problem about the volume control? :)

aha , but is there any other way to do that? :(

Hi I've built this amp: http://www.electronics-lab.com/projects/audio/006/index.html How can I do to lower/ raise the volume? Will I use a potentiometer? 50k ohm maybe?? ??? And you know the amp has two outputs so how can I control the volume by one potentiometer? Please help ;D Best wishes Mukhalled

Thank u so much for the full description ;D

Hi I have built this amplifier http://www.electronics-lab.com/projects/audio/006/index.html It works good actually and I thank you all for the support you gave me. :) Problem: when I connect it to my car stereo it sounds very very bad so how can it be used as a booster like they mentioned in the explanation in the link up? Maybe I've connected it in wrong way!? Please tell me how to connect this amp right :) Thank you and best wishes

Not yet actually but thanx alot anyway. ;D

Thank you ;D , but should I do some changes in the curuit if I chose another IC like you mentioned ( TDA15 52, 57 or 58)? ;D

Hi Is there another IC to use instead of (TDA1554 Two Channel Audio Amp Chip) in this project?http://www.electronics-lab.com/projects/audio/006/index.html Because I can not find this IC in the electronics shop. I need your help my friends ;)

Do you have a suitable bass-boost curcuit to add it to the amp? :)

Thank you so much Audioguru ;D

sorry I don't understand what you mean! ???

Hi How can I add bass-boost to this amp: http://www.electronics-lab.com/projects/audio/006/index.html :)

Thank you to answering me :)

hi again I've found this curcuit. what do you think about it?

Hi How can I get (+ and - DC voltage from DC voltage source) like a car battery? Is there any converter or something like that? Can you help me please I'm trying to build my own audio amplifier to add it to my car stereo. ;)

Thanks :)

Hi Which loudspeakers will be best to use to this circuit (ohm?)? Will I need to use a heatsink for the IC (LM1036N)? http://www.electronics-lab.com/projects/audio/039/index.html :) best wishes
