F200 Stereo HiFi Audio Vacuum Tube Preamplifier Replacement For JP200

F200 Stereo HiFi Audio Vacuum Tube Preamplifier 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:
