If it's the early tape duplicator who was out on Long Island, then they went
out pretty early.  And suddenly.  

It was run by Julius Koennens, I think, or Koenig- don't remember exactly.
He was a Holocaust survivor.  German, I think, rather than Austrian.  They
did duplication for Urania, possibly Livingston, etc.  I visited them a
couple of times, probably in the very early 1960s. I don't recall his
set-up.   If duping at high speed, it was a low multiple. I remember hearing
some A-B tests.  You still knew which was the sub-master and which the copy,
but not by much.  

Julie borrowed my unpublished 78 test of Seefried's version of Schubert's
"Das Lied im Gruenen," a spectacularly beautiful record, and was out of
business before he could return it.  I never knew what became of him or my
record.  

The less intimate one by Schwarzkopf was the one EMI issued.  The decision
was made by Schwarzkopf's husband, Walter Legge, no doubt.

No. I think they are long out of business. It was Dubbings.

Hello Tom, I Googled Dubbing Industries and only came up with my old field
of motion picture 
dubbing. Do you have a link?

Boy now THAT's something you shouldn't hang your hat on!

Shai -- how about a stroboscope wheel in the tape path? That's what I use,
just to confirm things 
are running on-speed. It's made by Dubbings Industries.
