Ron,
What you said is correct; however, the head still had to be driven by
the record groove. This would create an uneven lateral pressure on the
record groove and probably affected sound quality as well as record wear.
The ultona arm also had a weight mounted parallel to the arm that could be
moved back and forth to adjust the weight of the reproducer. I'm assuming
it was designed to approximate the weight of a diamond disc reproducer as
the majority of vertical records that were played on it were probably Edison
diamond disks.
