Super quality PCB. Solder pads are corrosion resistant. Soldering quality is very important in audio and high-frequency circuits. Thanks to the quality lead finishing on the Pads on the PCB, the soldering process is high quality. PCB quality greatly increases the operating performance of such circuits.
This is my project try re-make legend STK 4231 II chip amp IC. So many people like hi-fi sound of this STK series. This chip amp usually use on branded audio device like SONY and other. It still worth it to make and play with your audio system. On the datasheet it can supply with voltage of 51V DC (Recommend) and maximum at 75V DC symmetrical. The output power is about 100W per channel, it means about 200W in stereo.
You can find the installation of the circuit, bom list and all the technical details in the video.
