many thanks Hugh, bit of a dilemma though, the poxy bulb im trying doesn't work, the filament looks OK, i have ordered 4 new bulbs so that will be the test for me, unfortunately i do not have multimeter's or anything so i cant test to see if there is power to the bulb until i get the new ones which will obviously give me my answer. I dont know if these machines have a fuse for the bulb anywhere but i dont think they do.. Funny isn't it, I can take an Elmo to bits,(within reason), but a simple old Eumig i have hardly ever done anything on. I also dont have any service books for them.
