Hi Gabrielle,
I have a Kenwood A701A and recently bought a new liquidiser from Masterspares.co.uk, I spoke to Simon there and he sent my order with the liquidiser base adapted to fit. You may find that you only need the base. Give them a try, tel 02380 844338, give the model number of your Kenwood chef.
Good luck
Regards
Karen
