Introduction
1. Using original TPA3116 and TL074
2. The main circuit of the electrolytic capacitor signal adopts a chip electrolytic capacitor with a capacity of 4×470UF, which ensures a strong and continuous power support.
3. The resistors use high-precision chip resistors to ensure a good signal-to-noise ratio of the whole machine.
4. 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. Top-notch PCB quality.
5. Using a fully enclosed dust-proof potentiometer, the performance is more stable and more durable than ordinary potentiometers!
6. Fully shielded high-current inductors are used to ensure clear and powerful sound.
