Fans of recording gear necromancy rejoice: the Analogue Tube AT-101 is an accurate recreation of the original Fairchild 670 compressor unit, down to it's serious girth.

The sixty-five pound, six-rackspace AT-101 is hand-built to order, and every component is of highest available grade. While most of this unit's circuitry and design is exact, their have been a few improvements that serve to extend the life of the unit, and to eliminate some of the maintenance hassles that are standard with owning an original 670: the Lateral/Vertical switch has been replaced with a Stereo Link switch, and a power supply alteration made allowing controlled heater voltage switch-on to help maintain the life of critical tubes on power up.
