Reply to Circuit Diagrams & Replacement Parts

I just bought a Numark mixtrack off eBay on the cheap with a broken "Control" pot and some missing knobs.

Gonna be replacing the knobs with chroma caps, spraying the whole thing flat black, maybe change some LEDs out...

But I'm wanting to order that control pot ASAP so once the thing gets here, I can just crack it open and make the repair. This is the part that I need here. They want $7 for it and another $7.5 to ship it...I know good and well I can get it from mouser for like $0.75 BUT I don't have much to go on spec-wise as far as sourcing the right part.

Which brings me to the point of the post...is there somewhere out there with electrical diagrams or part lists or high res pics of the PCBs or something (for this or any other controllers)? I'm an electrical engineer by trade so having this type of resource could be dope for dreaming up and putting down mods...or just buying up broken shit off eBay on the cheap.

There's a pretty good thread on modding the Mixtrack but all the pics are from Myspace like 2 years ago so they're mad dead.
