6J1 Valve Preamp-Tube Amplifier-with 8 470UF Capacitor Filter-Valve Preamp Amplifier Board Kit-AC12V 0.8A or Above-2.0 /Stereo

Description: A valve amplifier or tube amplifier is a type of electronic amplifier that uses vacuum tubes to increase the amplitude or power of a signal. Connect this 6J1 tube pre-amplifier between sound source and and it can effectively filter digital flavor. Tube amplifier produces a warmer or more natural valve sound, make music and human voice is relatively good.  Specifications: Type: 6J1 tube (substitution model 6AK5, 6AU6, 5654 etc.)Channel Types: 2.0 / stereoVoltage & Current: AC12V 0.8A or abovePower Interface: 5.5 * 2.5 plugCircuit Board Size: 77 x 75mm / 3.03 x 2.95"Package Includes:1 x PCB Board1 x 2W 2.2?
