I'm missing something Jim.
How does the transformer decrease magnetic mutual coupling
effects from primary to secondary as it increases "bypass"
capacitance to effectively reduce turns ratio with
All I see happening is it making the system reactive while
the effective ratio barely changes if flux coupling is high.
