PCB size: 265X165MM Works voltage: 0-AC320V 0-AC320V 0-AC6.3V 0-AC6.3V 0-AC10V 0-AC10V 0-AC10V 0-AC10V Tube：need 4pcs 6z4 tubes + 6pcs 12ax7 tubes Founded in 1983, the French vacuum tube manufacturer JADIS, the designer JEAN-PAUL CAFFI itself is a person who is obsessed with music and has a good understanding of the physical characteristics of live music. He insists on maintaining the brand's pure A-class, vacuum tube self-biasing bias, and triode tube push-pull amplification. The products retain the French romantic tradition, and all reflect the exquisite elegance. JP200 is the most popular flagship preamp of JADIS. It consists of a 12AX7 two-stage common cathode class A and a first-stage direct-coupled cathode output device. At the same time, in order to make the circuit dynamic and wider, the overload resistance is better. The circuit is more stable, and negative feedback is introduced at the output and input stage current feedback. Therefore, double negative feedback can make the distortion very low. The previous stage amplifier has extremely high index and excellent hearing. We refer to the circuit, plus the components of the hifi level, made this very comprehensive preamp board, the vocals are very real, delicate, moist. The selected materials are double-sided gold-plated PCB, Phillips filter, German MKP10 capacitor, Phillips resistor and other high-end devices. Note: On this board. the 2pcs high voltage Regulator and the WIMA Capacitors are Used. but they are 100% origianl and works in good performance.
