Transformer Simulation in LTSpice

You should use mH rather than uH for 60 Hz. And the voltage ratio is the square root of the inductances.

V1 is not the voltage on the primary. Most of V1 is dropped across R1. You only have about 0.9V peak across L1 giving 1.6V peak across L2.

I won't repeat the valid points already made by another poster.

Circuit simulators are a real lot like dogs ......

and the first rule of dog training is that the trainer has to be smarter than the dog.
