This is worth knowing....we had a full-track Utah recorder from 1950, and
beginning around 1959 the family (with me as an unwitting accomplice in the
crime, since I wasn't old enough to protest) copied these tapes onto the newer
Wollensak half-track at slower speed and then used the older tapes. One of these
years I'm going to want to try and get at the original recordings still down the
centre of the tapes, since the dubs were not very good.
