[78-L] Long Play records

[David Lennick]

We should put one of those PTs under a microscope, but I've always played them 
with a 2.5 mil stylus. Some sound better with the 2.0 truncated elliptical that 
Kurt sells. This would be interesting to hear..I've heard the Artists Party 
that introduced the long play records, but not any other demo, unless this is 
the same thing with a special sleeve.

I've had one or two 78RPM Audiophiles. Mid 50s, I think.

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??
