I am quite the amateur in the audio world (still a student!), and as
part of a preservation internship I am assessing a collection of 10",
78 rpm, lacquered discs (w/ aluminum base) from the 1950s. As a part
of my learning experience I am trying to identify groove types for
these discs, and for others, and was hoping I could get some advice
from the experts out there on the ARSCList on how to identify groove
types. There seem to be a few websites out there, but I am loathe to
trust them without some more information.
Also, if any of you can point me to a trustworthy resource on
selecting styli for the various groove types and discs, I would
greatly appreciate it.
