We are a manufacturer of electronic components, electronic modules for a large number of products.We are the factory!With more than 10 years of PCB development experience, the product quality is good, the price is excellent.A large number of wholesale sales of global buyers, welcome to purchase.
1.Using the original TDA7498 TL072
2.The front input capacitor and inter-stage coupling capacitor use Siemens top-level capacitor 1UF, the electrolytic capacitor signal main circuit adopts Taiwan famous brand, and the main filter capacitor adopts Japanese Panasonic special electrolytic capacitor capacity 2 × 2200UF to ensure strong continuous power support.
3.The resistor uses high-precision chip 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 for the whole machine.
4.The PCB uses 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and the whole process of spraying tin to ensure the good passing performance of large and small currents. Best-in-class PCB quality.
5.Fully enclosed dustproof potentiometer, more stable performance and more durable than ordinary potentiometers.
6.Use red ring high current inductor to ensure crisp and powerful sound.
