[78-L] Long Play records

[Michael Biel]

Looking at the photos of the weight Ron sent me it looks like this could
slip onto the rear of the straight rod-like arm RCA was using around
1931, but not the fancy fish-tail arm they had earlier used.

This is interesting because it sounds like a weight RCA had for their
home recording discs in the early 30s except you would put it on the
pick-up head on the front of the arm to weight it down for recording. 
There was no exposed counterweight on either type of RCA arm of the
early 30s.

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!
