Description F200 Vacuum Tube Preamplifier Stereo HiFi Audio Tube Preamplifier Preamp Replacement For JP200 Description: Its main amplification circuit is consist of 12AX7 two-stage common cathode class A and a first-stage direct-coupled cathode follower. And negative feedback is added at the output and input stages of the input and output, to make the circuit dynamic wider, the overload resistance is better and the circuit is more stable. So double negative feedback allows for very low distortion, and get extremely high metrics and excellent hearing. Features: - Inspired by JP200 circuit, we optimize the components and design. The sound of this tube preamp is very clear, realistic and delicate. With standard RCA input and output, compatible with most common audio device, and greatly improve sound quality for your power amplifier or active speakers. - The required voltage is 2 groups AC320V-0 2 groups 6.3V 4 groups 10V voltage. Two 50W oxygen-free copper audio transformers are used, and the left and right channels are independently powered, which improves the separation and stability. - High-quality components are used such as Japanese potentiometer, US CMC816 gold-plated RCA terminals, double-sided gold-plated PCB, premium filter and resistor, Germany MKP10 capacitor and so on, to guarantee excellent sound quality.
