This object consists of a blocky metal object appearing like plates of metal stuck flat together with protruding attachments screwed to these on each side. This is attached by screws to a wooden plywood base. Around it, there is coiled a fabric-insulated yellow cable, with a standard wall plug at one end. Also emerging from the base of the transformer there is a short length of wire ending in a two-round-pronged female electrical connector.
