Im new to this forum, and electronics. I wanted to fix something. I foud my amplifier that was sitting in garage. It was working great until it started to act unpredictably. The volume starts to jump and bass starts to be very poor or way to strong. The sound is very poor and crunchy. So idecided to fix it. But after week i just give up. Any ideas what can it be? Its using tda chips
