1. 6J5 tube, NE5532. The main filter capacitor uses the 470UF/25V, and the coupling capacitor uses the imported capacitor 1UF.
2. The resistor uses a high-precision chip resistor to ensure a good signal-to-noise ratio.
3. PCB uses 1.6mm thick double-sided sheet, 2.0 oz copper thickness, spray tin full process, to ensure good passing performance of large and small current. First-class PCB quality.
4. Input and output with gold-plated RCA lotus seat, durable and beautiful
5. The board layout is reasonable, beautiful, and the current is small
