All parts of this product are original authentic, unadorned, pure quality; use of high-quality original parts, not only to ensure the safety and quality, long life, more importantly, to make the actual performance to achieve the design goals of a strong guarantee. The pursuit of first-rate quality is our consistent aim.
1. Using original TDA7498 TL072
2. The pre-input capacitance and inter-stage coupling capacitance are Siemens’ top capacitor 1UF. The main circuit of the electrolytic capacitor signal adopts Taiwan famous brand. The main filter capacitor adopts special electrolytic capacitor capacity of 2≠2200UF to ensure a steady stream of powerful power support.
3. The n-resistors use high-precision chip resistors, and the main circuit uses ÷1% metal film resistors with precision to ensure a good signal-to-noise ratio.
4. 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. The use of fully enclosed dustproof potentiometers, the performance is more stable, more durable than ordinary potentiometers.
6. Red ring high current inductor ensures crisp and powerful sound.
