Well, that was very quick! For a suplementry question (no extra
points i'm afraid) has technology moved on since the 70's? or are
todays chargers still a transformer, rectifier and a fuse in a box?

They have moved on. The older ones had to be watched to prevent them
over-charging and damaging batteries. The more modern ones at least
stop charging when a full charge has been put into the battery. Even
better modern ones use a three stage intelligent charging process.
