Capacity Capacitor: The main filter electrolytic capacitor features a total capacity of 6600UF, supporting enhanced performance and more stable operation of the amplifier system. Strong Power Support: Two 8A rectifier flat bridges provide a continuous and robust power supply to the amplifier board, helping maintain performance under load and reducing voltage sag. Accuracy Resistors: Precise surface mount resistors ensure a fine signaltonoise ratio and contribute to clearer overall audio quality. PCB Design: The 1.6mm thick doublesided PCB with a full tin spraying process delivers strong current handling and reliable durability for longterm use. Applications and use scenarios DIY hifi amplifier builds and upgrades that require stable power delivery and low noise Compact home audio systems or desktop amplifier modules where reliable power and signal integrity are important Prototyping or educational projects that benefit from precise components and a durable PCB for experimentation and testing
