It was quite some time before more advanced editing techniques made

recall that it started in the middle of the third series.

Not quite sure what you mean by this, presumably you are referring to
the advent of electronic editing.

What was it that precluded electronic editing by dubbing from one tape to
another, as they did until a few years ago? Was it simply that copying from
one tape to another in the early days brought the quality below acceptible
broadcast standards?



The 10 second run-up of a tape machine (or telecine) to achieve sync was a
problem until electronics were devised to enable the machines to go from play
to record on the fly at a predetermined point. Eventually Ampex devised a
quad machine that would do instant starts, first used on the Andre Previn
concerts.
