Well in the Carlson sch which I listed the field coil is not filter, it is going from the rectifier to the chassis, that is being a load. However there is a choke there for a filter, this is why I said it is either choke or field coil. It is possible there is none but I would be surprised as filtering would degrade unless a large cap is used.
