To answer other people’s question about the bolts for the rack I included a photo they are taped in the styrofoam! 
Take great care when putting together this simple case. The legs are easily screwed in but hard to get the slant that is required. The legs didn’t meet in the proper spot and one of the screws jammed , and in the process of removing to try again the mdf broke. Luckily Wayfair has great customer service ! The product matched and fit my “all in one” record player . Not very sturdy so would suggest, if your installation works, that you may want to secure to wall so your record player remains steady.
