Kuuleyn Vacuum Electron Tube Valve Preamp Amplifier Board Headphone Amp Parts Features:
【Great for】Connect the 6J1 tube pre-amp between sound source and amplifier, it will effectively filter digital flavor, the music and human voice will be relatively good.
【Function】Eight 470UF capacitor filter is very clean, excellent power system to no hum, filaments are powered with DC 12V and need to be connected in series in order to reduce noise. 【Practical】Coupling capacitor is electrodeless electrolytic capacitor with high frequency and low resistance. 【Portable】Using DC 5.5*2.1 socket and AC 12V transformer, you can also use AC 12V transformer without plug, just need to weld the power cord onto the circuit board. 【Application】This kit comes in parts so you can assemble them together by yourself, enjoy the process of building your own tube amplifier.
