Here is a vintage matched stereo pair of 1965 Fairchild 661-TL gate audio processors. These particular examples, serial numbers 706 and 711, are in very excellent all original condition and include the original vertically-oriented mounting bracket. The 661 Gate shares a nearly identical schematic to Fairchild’s 663 compressor, which is unparalleled when it comes to compact compressor modules. The 661 is commonly modified into a version of the 663 that has become surprisingly desirable.
Recently purchased from a studio in Boston, along with several other Fairchild units currently on eBay, these were being used until just recently and had remained installed and functional for several decades. Both units, or the stereo pair, are being sold in excellent working condition.
