About the PA70
The Jadis PA70 is a current-production French stereo valve power amplifier. It uses a single-chassis, pure Class-A push-pull/ultra-linear design derived from Jadis’s KT170 platform, with automatic bias and separate driver/power-stage supplies. Four KT170 output tubes deliver 50 W per channel; small-signal valves are specified by Jadis as two ECC83 and two ECC82. It is offered with gold or silver transformer/faceplate finishing and in 117 V or 230 V versions. The PA70 is intended for use with an external line-level preamplifier and passive loudspeakers.
