The MKS and MKA were superseded by the MQS and MQA in 1960. The MQ line of meters were identical to the previous MK meters except for two things: The brake magnet was redesigned from a single magnet to a set of three Alnico V and one Alnico VI magnets (the Alnico VI magnet was movable and was used as the full-load adjustment) on the left and right sides of the stator. The other major change was to replace the jewel bearing used in the MK with a magnetic suspension similar to the one incorporated in the GE I-50 meter. The MQA was made in smaller quantities before being dropped because of decreasing demand for singlephase A-base meters.   MQS
