Feature

●ADOPT 6J1 TUBE: This preamp board uses the original 6J1 tube, the sound is soft and beautiful, with more concentrated low frequency.
●EXCELLENT CAPACITOR: The main filter capacitor adopts the original 1000UF 35V, and the coupling capacitor adopts the capacitor 1UF.
●METAL RESISTOR: The resistor is made of 5 rings 1% metal resistor, which ensures a good signal to noise ratio of the whole machine.
●DOUBLE SIDED PCB: Using 1.6mm thick double sided board PCB, 2.0 oz copper thickness, to ensure good passage of large and small currents.
●REASONABLE WIRING: The tube preamplifier module has reasonable wiring, low current noise, and adds green background LED, beautiful and durable.
