[78-L] Long Play records

[Ron L'Herault]

Any mention of a counterweight for the arm?  I was given one recently, no
manufacturer's name.  It is a heavy cast metal weight, painted black with a
U shaped, felt lined channel.  The rounded end of the thing has a metal tag
indicating that it is for LP records.

Subject: [78-L] Long Play records

I was just going through a pile of records I got from Philadelphia and I
found the "RCA Victor Demonstration Album", a 10 inch 33 1/3 record.  This
record was designed to demonstrate the Long Playing transcription records
from the early '30s and the sleeve notes contain instructions about how to
play them.  It says only to use the "orange shank long playing needle".  It
also says not to use this needle with standard 78 rpm records.  Elsewhere it
says, "Twenty minutes of delightful entertainment have been recorded in its
super-fine grooves...".  This implies that the needle and groove are of
different dimensions than standard 78 grooves.  I have always believed that
these transcriptions had the same size groove as normal 78s.  Am I wrong?
 Does anyone know about this??

Another record I found in the same pile is an Audiophile microgroove 78 rpm
record, with the instruction, "Play with one-mil stylus only.".  I've never
seen one of these before, but they must be a product of the '50s since there
would have been no one-mil styli any earlier.

Thanks!
