Audio amplifier noise easy removal near 100% perfect - LM386 circuit experiment

I’ve been watching quite a number of #DIY #homeMade method on #YouTube #Videos about #HowTo remove noise from the LM386 audio amplifier circuit which can be done in a few ways. But here experimented a new way using mini step down transformer to remove the distorted sound and it turns out to be very effective which is near 100% free from noise. The problem with the LM386 IC is very sensitive to ground loop voltage. Even our fingers could actually disturb the signal. As you can see the crackling noise and so
