Founded in 1983, JADIS is a French vacuum tube manufacturer. Its designer, IEAN-PAUL CAFFI, is a person deeply obsessed with music and has a profound understanding of the physical characteristics of live music. He insists on maintaining the brand's consistent features of pure Class A, vacuum tube self-powered bias, and triode push-pull amplification. The products retain the romantic tradition of the French, embodying exquisite elegance and dignity. JP200 is JADIS's popular flagship pre-amplifier, which consists of a 12AX7 two-stage common cathode Class A and a single-stage direct-coupled cathode output circuit. To make the circuit have a wider dynamic range, better overload resistance, and greater stability, negative feedback is introduced at the output terminal and input stage current feedback point. Therefore, the dual negative feedback results in very low distortion. This pre-amplifier boasts excellent specifications and sound quality.
We have referenced the circuit design and combined it with high-performance components to achieve comprehensive performance. The electronic tube pre-amp, which shares similar characteristics, produces vocals that are very realistic, delicate, and smooth. The low frequencies are elastic, while the high frequencies are precise and coherent.
The selected materials include high-end components such as double-sided gold-plated PCBs, Philips filters, German WIMA capacitors, and Philips resistors.
PCB size: 264X166mm
Weight: approximately 568g
Note: The 8 electronic vacuum tubes on the board need to be matched by yourself!
