Does anyone have a source for custom PC mount transformers that they can share? I need to convert a 7805 based supply from a 230VAC line to 277V and 230V 'standard' transformer primaries are only OK'd for use 10% above their rated voltage. I am hoping to be able to have a few specials wound, but I need a source.....anyone, please?
