Altec 9073A Vintage Graphic Equalizer Rare Motown Eq

I'm selling a really nice Altec 9073A passive graphic equalizer. These are very similar to the Altec 9062A's and Langevin EQ-252-A's, also known as the Motown EQ. The main difference is that the 9073A is 6 band instead of 7 band so it has some unique frequency options. This is actually the only 9073 I've ever seen. It's in beautiful condition and sounds incredible. It comes with the pictured XLR pigtails for input and output.
These sound absolutely amazing and are some of the smoothest sounding eq's I've ever heard. I actually prefer them to the sound of Pultecs for tone shaping since they have more frequency options, but can sound just as smooth.  Its completely passive. It has no internal amplifiers and requires no power for its operation. However, because it is a resitive network it does have an insertion loss. 
Let me know if you have any questions and check out my other vintage audio gear. See below for more history on this line of eq's

INFO/HISTORY: The Langevin 252A is the 2nd true graphic equalizer ever made (the even rarer Cinema Engineering 7080 being the 1st), making these a true piece of music recording history. Designed by Art Davis in the late 1960's, this was a "work-horse" of the industry. Altec equalizers were used by A&M Records, Columbia, Universal/Decca, MGM, Paramount, United Artists, and Walt Disney to name a few. Motown actually built these into custom boxes that included their own tube makeup amplifier for unity gain.
