Hi all,
I have build an amplifier circuit using the TDA2003 IC and this circuit: http://www.electronicspoint.com/attachments/7w-tda2003-audio-amplifier-circuit-gif.13252/
The amp works great at very low volume, and when i bring the volume up a loud buzz suddenly appears. If I bring the volume up higher, the buzz stays at the same volume and the audio gets louder so it can be heard over the buzz, but it's still very annoying as it's always present.
So I came here hoping someone would have a suggestion on how to get rid of this problem.
Thanks.
