A bit of a tough one I'm afraid.
Parts are no longer available for these so the best you can hope for is if someone on here has any spares. I've seen people use large flat headed screws sawn down but it isn't an ideal fix to be honest. The mains lead is much easier, it is a standard figure of 8 lead which is used on most portable & some mains appliences such as Sky boxes etc...........

The use of metaphors should be avoided like the plague. They're like a red rag to a bull to me.
