Hi. I've been poking around trying to explain a 10volt difference between PSUD2 and LTSpice results for an EZ81 based power supply. It's not a big deal (the amp's been working for years) - I'm just trying to understand the use of both tools for Power Supply design. I've been assuming that the difference is in the models of the EZ81. I kept trimming the design down until I reached the attached configuration. The Transformer current matches the Diode current, but the Resistor current (Mean) is 7mA less. What am I missing?
