I was amazed at the quality of sound from this little mono amplifier. No wonder it was so widely used. Unfortunately it is no longer produced by Texas Instruments.
I watch quiet a few video tutorials about building this little amp. The trick is to get it quiet, no hum or buzzy high sounds. A couple of video’s I watched were all about correct wiring of amplifiers which helps reduce hum. Getting the correct layout is a must for amps to sound great and it is worth spending the extra time to get it right. I have bought one of these on-line and did a comparison of power video, thinking about it I should have also compared sound. Anyway’s mine worked better, yeah I can not believe it. Here is the video take a peek. Power comparison video LM386.
This is the working amp
