My parents got a pre-Dial-a-Brew Norelco in the early 70's. It made great coffee compared to the Corning Electromatic percolator it replaced. I always wondered about the design of the basket lid on those models. Often during the brewing process, more water would land in the lid than it could accommodate, and it would end up draining down the center hole in the basket assembly, which served to weaken the brew strength.
