  1. 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:

    Please can you suggest something to do...  ;D

  2. 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

  3. 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

  4. 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

  5. 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

  6. 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.

    ;)
