Dennis' info is important because I think it is part of the technical
info encoded on the Victor ledger sheets that is being IGNORED by the
Victor discographical project. Nick Bergh did a presentation at ARSC 2
years ago which shows that he has gone a long way to understanding that
ledger technical information. Of course it all means nothing without
access to the info on the ledger sheets for the particular recording --
and librarians and archivists do not consider technical info to be

Steve, won't your ears tell you whether phono-EQ was used or not? It can
sometimes be hard to tell which EQ setting was used, when some EQ
was used, but usually not so hard to tell if no EQ was used. That's not
small difference. As in many cases of determining EQ, the ears are the
most reliable equipment.
