1. Using TAS5630, OPA1632DR, TL072
2. The main filter electrolytic capacitor adopts a capacity of 470UF/100V*4 to ensure strong and continuous power support.
3. The resistance uses five-ring metal resistance, and the main circuit adopts a five-ring metal film resistor with an accuracy of ±1%, which ensures a good signal-to-noise ratio of the whole machine.
4. Fully shielded high-current inductors are used to ensure a clear and powerful sound.
5. The PCB adopts 1.6mm thick double-sided board, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents.
