Hello,
I'm a let's say a developing intermediate at electronics and understand a few advanced concepts
. I recently built a simple two channel amp based on LM3886 with a p2p construction. The amp works fine and I'm satisified with the sound. Very low noise, great performance and no artifacts, except one..
When I turn the volume control the speaker cones move in and/or out quite a bit depending on if I'm turning it up or down, and in under a second they move back to initial position. There isn't any audible effect on the sound but this cannot be right.
I'm suspecting it's a DC decoupling issue somewhere. Can someone please explain why and where does this phenomenon usually occurs.
P.S. I tried picking the best section to post this, failed and decided to post it in the chipamp forum since this is a LM3886 build. Feel free to move the thread if I missed.
Thanks
