So that people can get a little grasp, because it's not output transformer coupled, so then what is it???
Why don't you call it what it is? An amplifier coupled by an RF transformer, bypassing traditional output transformer problems? Instead of making up stories about how a transformer isn't a transformer- sounds a little like the Emperor's New Clothes after a while.
That children's story is not just for amusement- it was devise to teach to children how a story can be made up merely for purposes of looking good, or failing that, not looking bad. And what happens when you see through the story.
