I've mentioned it before but it bears repeating..Pathe type vertical cut discs
(with the wider groove) play BEAUTIFULLY with a 2.0 mil truncated elliptical
stylus. Unless the disc is badly damaged, I've found it will track with no
problem with this stylus.
Edison, Brunswick verticals, Rishell etc. may do well with this stylus also,
but I've found a 2.5 mil elliptical (Shure SS78E and good luck finding one of
those) to be perfect.
.7 mil styli work best on 33RPM verticals (Muzak, World Program Service).
