Default Re: Adapters Voltages?

"BTW I am talking about 50/60Hz transformers, are we on the same subject here?" Yep, simple linear power supply with iron core transformers, with simple bridge and filter cap, not regulated output.
28V no load and 12V full load, that is the worst transformer regulation factor I have ever heard of, no load of 1.8 factor (no load is 80% higher than full load) spec is about the worst I ever run into.
