Analogue Tube unveils the AT-101, a faithful recreation of the original Fairchild 670 stereo limiter.
The AT-101 is built using traditional point-to-point wiring methods and standard turret component mounts. The audio path and power supply are completely free from any printed circuit boards. The AT-101 like the original Fairchild 670 has been assembled completely by hand and uses high quality modern components. The tube complement is exactly the same, using a new generation 6386 remote cut-off triode developed to replace the original 50 year old tube types many of which were used in the Fairchild 670.
Whilst most of the AT-101 is the same as the original there have been a few minor changes to the front panel and electronics, 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. A simple electronic traffic light system monitoring temperature has been added.
The AT-101 is available for £11,500 ex VAT ( $20350 / €14700 approx.). All production models come with a choice of front panel colours finished in enamel. Each unit is shipped with a fully protective foamed-out Peli road case with wheels as standard. There is a 6 week lead time.
