Buffer HiFi 6J5 Bluetooth 4.2 Tube Preamp Amplifier Stereo Preamplifier with Treble Bass Tone Ajustment(Black)
- 1. Using 6J5 tube, NE55322. The main filter capacitor uses the 470UF/25V, and the coupling capacitor uses the imported capacitor 1UF.3. The resistor uses high-precision chip resistor to ensure a good signal-to-noise ratio of the whole machine.4. PCB adopts 1.6mm thick double-sided sheet, 2.0 oz copper thickness, and tin-spraying process to ensure good passing performance of large and small currents. First-class PCB quality.5. The input and output are made of gold-plated RCA lotus seat, which is durable and beautiful! The board layout is reasonable, beautiful, and the current is small.
