My Drive Units

If you have cherished KEF speakers and you wish to replace items which are faulty, or if you wish to build speakers using KEF drive units and you cannot obtain the items you want, let me know and I may be able to help. I may know of individuals who have spare units or I may know of a contact who can provide the required item(s). I wish to enable the 'recycling' and continued existence of KEF systems from that period. In the Forum anyone can also advertise items for sale or exchange.
