EDIT: Wow, theta was set to 1. Sorry everyone, if you see a degrading AC power supply make sure to check your Theta value. I threw this in to Tips & Skill, because I'm hoping to learn something here. I've used LTSpice before, but it's been a few years. Setting up a simple AC -> logic level power detection circuit for 24-48VAC. The circuit we are already using works, but I'm going back to simulation to see if I can improve the noise we currently have in the circuit. Anyways, when I setup this simple analysis  I get an AC power supply that degrades over time, and I know I've got to be missing something simple but I just can't figure it out.  TIA
