  212. This circuit illustrates two ways of creating a transformer.The first method uses the transformer component with the    parameter 1e-4/1e-2/.98.  The second method uses a pair of  mutually coupled inductors.  Notice that the coupling arisesfrom the Grid text:                                                                                                          MUTUAL:L1/L2/.98                                       The circuit also shows how to create a five terminal center-tapped transformer macro.  Note that the symbolic labels forthe two transformers must be different.                     To view the contents of the macro CENTAP, load the file.
