About the JPL MKII
The Jadis JPL MKII is a French-made, all-tube stereo line preamplifier. It provides four standard line-level RCA inputs plus a tape-monitor input, with a dedicated high-impedance CD input buffered by an ECC82/12AU7 tube to minimize source-loading and impedance-matching issues. Its tape-monitor section includes a buffered fixed-level tape output. The MkII revision uses a tube-regulated high-voltage power supply, employing EL84 and EF86 valves for improved supply stability and low-noise operation. Audio gain stages use three ECC83/12AX7 tubes. Controls include source selection, tape monitoring, balance, volume, and muting. It is intended for connection to a separate power amplifier; it contains no phono stage, DAC, headphone amplifier, digital inputs, or wireless/streaming functions.
