Hey guys, could really use some help taking apart my Promax J-1. I want to deoxit the volume and EQ sliders but to do that I have to take out the center chassis. I've got it opened up, I took off the handle and three chassis screws but now I'm stuck. The chassis is loose but is still being held in place. What am I overlooking? Does anything have to come off the front, Tape Decks? Etc.. Could really use all the help I could get. Pictures would be awesome!!! Thanks.
