Re: [ARSCLIST] PreRecorded Tape Duplicators
That's some fantastic information.
I have a number of the Mercury 2 tracks and a few of the 1/4 tracks
as well. I had no idea that they were just one generation from the
session tapes. The sound on these varies but the best ones I have
( Adventures in a Perambulator/Hanson and Hary Janos/Dorati for
example) sound amazing. I have most of the "Russian" Mercuries on
1/4 track and prefer the sound on these to the reissued vinyl.
The Command titles can also sound very good but I've had a difficult
time finding minty copies of these (just plain bad luck I think) but
I've always admired the sound on the recordings from 35mm. Finding
out that Fine Recording made these and the details you've provided is
very much appreciated. The back on one of the 1/4 tracks state
"Originated and Produced By Enoch Light,.. Grand Award Record
Co.,Inc., New York". Are there any links to Fine Recording in general?
I do have a few staggered heads, 1/2 tracks (The Atlantic) and I'll
do as you suggested and transfer them in my editing software.
These very early tapes quite often have prices printed on them and
range from $9.95 on up to well over $20 per tape. Considering that
these are 1950's-early 60's dollars they were certainly for a
discerning few. I've come the the point that I really try and obtain
and acetate copy of the 1/4 tracks if I know that they're available.
Collecting these tapes, you stumble across some real gems sometimes.
A couple of weeks ago I heard a fantastic sounding 5" 71/2 ips tape
of Doc Evans. The include catalog was from 1957 and the tape was a
"sampler" on the Stereophony label. Ewing Nunn was the engineer and
the sound was stunning! We believe this to be partly due to it's
being recorded on Scotch 111 as the high frequencies didn't show a
bit of degradation.
This is an interesting question. I am cross-posting your question
and this reply to the Ampex list because those guys will know all
sorts of details I don't.
The first written account of a commercial reel duping facility I
have is from Radio & TV News, April 1952, by Leon Wortman,
desribing the custom setup at Audio & Video Products Corp, NYC.
What was made there, out of in-house modified Ampex 300 decks, was
essentially what evolved into Ampex's duplicator systems, but Ampex
made some changes. The system Wortman describes duped full-track
and half-track tapes. By the time Ampex's system came out, it
allowed for two tracks. The earliest manuals I have for Ampex
dupers indicate the master tape could be recorded at twice the
speed of the dupes or at the same speed (ie the master playback ran
at both the same speed and twice speed of the dupers, and the
dupers could run at half the speed of the master playback, too,
offering a wide range of master and slave-product speeds). In the
US, I think Ampex owned the "plug and play" duplication market into
The early 2-track stereo tapes, especially the classical products,
were a premium-priced niche product with a demanding audience. So,
at least in the case of Mercury (and I think RCA and Columbia,
too), the duping was done in small batches in-house. In the case of
Mercury, the dupe masters were one generation removed from the 3-
track session tapes. I assume there was an extra generation loss at
most other places. Given the vagueries of 1-mil tape in those days,
plus the mechanical demands on the duping equipment, I'm amazed
that these tapes generally sound as good as they do. The ones I
have heard are hissy but otherwise quite good as far as music
reproduction. Some tapes from the smaller players have strange
azimuth, but one can tune this by scope and ear if your playback
deck has an accessible azimuth screw. Early on in the 2-track days,
there was a brief format war between Magnecord's staggered tracks
and Ampex's stacked tracks. Ampex used its market-share muscle to
quickly kill the staggered format, and Ampex personnel argued
vehemently for a standard format in several industry publications
and meetings of the time. I have a few staggered-format tapes. As
long as the tape itself isn't too warped/shrunken, I've had good
success fixing the staggering in Soundforge, and ending up with a
properly-phased stereo image. In some cases, adjustment was
required every 10 minutes or so, but that was with somewhat warped
tapes. One of my favorites of this type is a first-generation
"Sound In The Round," both volumes, from Concertapes. The
subsequent versions of this I've heard are inferior, as is the LP.
The quarter-track format, which came along at the end of the 50's,
is what moved duped reels to a larger audience. Now, at a
reasonable cost of production (half the tape, half the duping
time), a full-album product could be offered, still at a premium to
LPs. At first, at least in the case of Mercury, some or most duping
was still done in-house. I think RCA and Columbia kept their duping
operations in-house, too. Ampex got into the tape duping business
in the early 60's, and a company called Bel Canto got big by the
mid-60's. Ampex duped tapes for the European classical labels Decca
and DGG, and Bel Canto and Ampex eventually did the duping for
Philips/Mercury by the mid and late 60's. I think Ampex ended up as
by far the biggest duping operation in the US.
As for smaller operations, I can only talk in detail about Fine
Recording's duplication division. This was started in the late
50's, with Enoch Light's Grand Award and Command labels as the
first big clients. The operation eventually took up the entire
basement of the Great Northern Hotel, had its own street entrance
and offices and employed dozens of people. The initial formats were
2-track, full-track and quarter-track reels, but the operation was
the first or one of the first to do 4-track cartridges and then 8-
track cartridges in NYC, and one of the first or the first to do
cassettes in NYC. The equipment started out as Ampex duplicators
but was heavily modified, including special heads for new formats
from John French's father and also IEM. There was a dedicated dupe-
mastering room and a dedicated maintenance guy just for this
operation. At peak there were two quarter-track/8-track lines (with
rolling loader bays to put the tape in the cartridges) and a
separate full-track line for radio commercials. For 2-track and
quarter-track reels, experience taught that 1:1 master to slave
speed ratios ended up with the best playback quality, so the dupe
masters were recorded at 7.5IPS and the dupes were 7.5IPS. What you
lost in the master recording you gained in the duping. The primary
tape brand was Audiotape. Judging from pictures of the dupe-
mastering room I've seen, some dynamics-control was applied (there
was a UREI compressor patchable into each channel). In the case of
Command titles, if the master was a 2-track, the dupe master was
made from the master. If the master was 35mm or 3-track tape, the
dupe master was made from a 2-track created when the 3-2 mix was
made for LP mastering. From what I've been told, duping was a
mildly profitable business. I'm not sure how big the duped-reel
market ever got. I'd assume it was a tiny fraction of the LP
market. Interestingly, duped cassettes surpassed LPs after the
Walkman Revolution, and then were obsoleted by CD's.

Subject: [ARSCLIST] PreRecorded Tape Duplicators
I've been collecting prerecorded reel to reel tapes (classical
and jazz) for a while now and while myself and a few of my
fellow enthusiasts have found a good deal of information
regarding the titles that were sold, we don't know very much
about the duplicating facilities that made them. There are
scattered accounts of the Ampex factory such as the one on Mr.
Hess's site which I found very interesting. But I've never seen
any documentation of RCA, Capital, Columbia (and the other
monikers their tapes were sold under), Stereotape (which I
believe began as Bell and Howell and was latter to become Magtec)
not to mention all the smaller operations.
The information I'm seeking is more of the nuts and bolts such
as years of operation, tape production, any details regarding
their duplication lines (duping speeds, tape stock used) and what
labels they produced these tapes for.
I do need to pose the question to the gentlemen on the Ampex list
for more details on their operation but I'm concentrating on the
early 2 track releases first since finding first hand accounts
regarding these will become less and less likely as time marches on.
Thanks in advance for any information regarding these tapes even
if it's only a lead.
