Drawing and Simulating auto-transfo

Question asked by mlabro on Mar 1, 2006
It would be nice to be able to draw (symbol) and simulate a auto-transfo either ideal (ratio N1:N2) or with a given inductor value.
These are very useful in the tuned collectors of transistors or to increase the inductor while decreasing the capacitor in a given LC of a notch filter or to simulate the input toroid of a discrete splitter (ratio : 1.1442 to make 75R to 37.5R often represented by 7 turns for input and a tap point from ground at 5 turns around a toroid).
