I have to agree that Heathkit instructions often carried completely bogus theories of operation. I remember my 3-transistor experimental circuits set. When the manual tried to explain transistors it had a little guy at the top of the stairway which was the emitter waiting at a door that was opened and closed by a guy from the base wire and when they went through the door they went out through the collector (PNP transistor). Semiconductors are so simple that it would have been easier to give a real explanation than this ridiculous piece of bologne!
