unplug from mains,remove cover by undoing srews at back.Remove cover,beware edges are very sharp.On the right hand side towards the front,just gehind the controls you will see a brown thing with wires attached,straighten the metal at top and bottom and remove and you will the have the lamp.Screw it out.It is a 20 watt 240v amp quoted at £6.99 on net but i am sure a good electrical shop will be a lot cheaper
