Introduction
1. Using original 6J1 electronic tube, original NE5532
2. The main filter capacitor adopts the original 680UF/16V, and the coupling capacitor adopts the imported Philips capacitor 1UF
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 sheet, 2.0 oz copper thickness, and full tin spraying process to ensure good passing performance of large and small currents and PCB quality.
5. The input and output adopts gold-plated RCA lotus seat, which is durable and beautiful!
6. The board wiring is reasonable, beautiful, and the current sound is small
7. Bluetooth adopts Qualcomm QCC3034 Bluetooth 5.0, Bluetooth supports APTX lossless playback
