1. Using TDA7498 TL072, fully enclosed dustproof potentiometer, performance is more stable, and more durable than ordinary potentiometer.
2. The red ring high current inductor is used to ensure the sound is clear and powerful.
3. The front input and the inter-stage coupling use Siemens' top-level s 1UF. The electrolytic signal, and the main filter adopts Japan's Panasonic special electrolytic 2x2200UF to ensure strong continuous power support.
4. High-precision chip resistors are used for the resistors, and the main circuit uses a five-ring metal film resistor with an accuracy of ±1%, which ensures a good signal-to-noise ratio of the whole machine.
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.
