DIY Sontec MEP 250 works perfectly / clean build

Hey All, 

Here is a pretty legendary unit but built by me! Check out the build.  It's super clean and I used the best parts I could buy.  This was a build directly from the prodigy professional forum a few years back, I just hadn't gotten around to it. Unfortunately, I need to let this go to fund a console we just purchase for our studio THUMP here in brooklyn.  This thing has sat on our mix bus insert for a long time. If you have any questions please let me know. Here are some more words from the internet: 

The Sontec MEP-250C is a stereo 5 band parametric equalizer that is one of the earlier EQ's used in mastering. Long favored for it's extremely smooth, uncolored sound, many current equalizers owe their heritage to the Sontec. This unit is in nice working condition, and useful as a channel EQ, program EQ, mastering EQ, or any other function where you would use a high quality EQ.
