We have all tried various tweeks including I put a paving slab would you believe under my first turntable a Michel Focus one, however try this - go to the cheap 99p or £1 shop and buy a roll og what I can desribe as grip, its called anti-slip rug gripper 55x125cm and cut it into 14 x 17 inches. There is enough to make 4 pieces,,,,now place one under each piece of equipment ensureing that each piece is big enough to cover all 4 feet. Simple, apart from ensureing the equipment does not slide everywhere Im sure some form of black magic is going on! I chose blue as it matches the glass shelves on my rack but it also comes in black, grey and white
