Active noise cancellation circuit with transformer -- 2

In the file u see a circuit, in which a controlled voltage source has been used, and it connects 2 branches of the circuit with a control signal comming from memory block and a gain of (-1). If we disconnect this control signal, then we see a noisy output in oscilloscope of Common mode Voltage (CMV) and Common mode current (CMC). But with this control signal we have reduced noise.
The task is to keep using Memory block and the gain, but to use an ideal transformer instead of using Controlled Voltage Source and get the same output in the CMV and CMC oscilloscope.
