I require a replacement blender for my Chef or Major

The blenders are compatible with any Chef or Major which was manufactured from around 1976, although they will not fit the A701 or A707 models. The A901/ A907 models are compatible. Your model number can be found on the underside of your Chef or Major.

The blender has a 1.5 litre working capacity for cold ingredients and a 1.2 litre capacity for hot ingredients.
