Using original IRF240 MOS transistor.

1. The input coupling capacitor adopts German imported Weimar capacitor 50V/3.3UF, and the main circuit of the electrolytic capacitor signal adopts an imported brand.

2. Five ring metal resistors are selected as the resistors, and the main circuit adopts a five ring metal film resistor with an accuracy of ± 1%, ensuring a good signal-to-noise ratio of the entire machine.

3. The PCB is made of 1.6mm thick double-sided sheet metal, with a thickness of 2.0 amperes of copper and a full process of tin spraying to ensure good current passing performance. First rate PCB quality.

4. The wiring layout of the entire circuit board is quite rigorous and reasonable, and the overall PCB wiring adopts a single point grounding method. This power amplifier board works stably and reliably, with a high output power; The voice is beautiful and round, with a broad sound field. Strong three-dimensional sense, stable and solid low-frequency, excellent signal-to-noise ratio, and wide dynamic range; Clear details and excellent transient response, able to handle various types of music with ease, performing well in home playback environments.
