Product Details:
① Using the original 22SA1943/2SC5200 MJE15032 MJE15033
② The main circuit of the electrolytic capacitor signal adopts the famous brand of Taiwan. The main filter capacitor adopts the gold NOVER audio special capacitor capacity of 4×10000UF-channel, adopts the rectifying flat bridge of 25A and above, and guarantees powerful and continuous power support.
③ The resistor uses a five-ring metal resistor, and the main loop uses a five-ring metal film resistor with an accuracy of ±1%, which ensures a good signal-to-noise ratio.
④ The PCB adopts 1.6mm thick double-sided plate, 2.0oz thick copper, and spray tin process to ensure good current performance. First-class PCB quality.
⑤ Due to the direct and even test amplification, the entire circuit has no coupling capacitance, which reduces the distortion to 0.002%.
