due to the amount of kit in the av rack I have the tv sitting on a glass riser shelf. Just got a new tv and the tv stand is a little larger than the old tv, so I need to source a new riser stand. Ideally 70cm wide by between 40cm to 50 cm deep, with a rise of 10cm to 14 cm to fit my sky box underneath. I'm struggling to get this exact size, can anyone help? Or even a place where I can order the glass and somewhere to source the legs?
