This is the little Hi-Fi I built. It is based on two Wondom serie boards from Sure Electronics, a company famous for manufacturing printed circuit amplifiers.
The important premise is that this project was born with two purposes: to create a Hi-Fi stereo starting from a minimum budget and to gain some experience while having fun. This means that someone more experienced in Hi-Fi than me will turn their nose up at some of my choices, probably with good reason. I am sure this project could be put together with better components, but that is not its purpose. Be lenient.
The two cards used are the AA-AB32155, capable of 2x15 Watt in class D based on the Tripath TA
