Thanks Mark! It looks like I have the wrong bracket, and possibly the wrong amp. My bracket is a triangle looking bracket that stands straight up off the top of the amp. My amp also has the coil looking thing (In the far right of your picture) coming off the back, to the right of the fins. My model number is 91BMP11, serial number 61SAA-0654. The DS-501 is dated 6829. Would you think I have the wrong setup? This amp has the correct plugs to fit my bluelight, but that bracket is bothering me now! Mark, Thanks for your help!!!
