[78-L] Acoustical playback (was: Old Geezers)

One immediate example I can give is with U-S Everlasting cylinders. The process involved in their manufacture involved "welding" a seam in the celluloid sheet surroundin the fibre core, which is why many are often found with the celluloid precisely split today as the celluloid shrinks. Played with modern equipment, you get a distinct "swish" 160 times a minutes as the stylus passes over the very fine weld. This is inaudible (or at the most, very nearly so) on period instruments, and the recorded sound is full and brilliant. The disadvantage of playing U-S records on a traditional instrument is that sometimes this same shrinkage throws the groove pitch off vis-a-vis the feed screw pitch, which over the course of a 4 minute record can cause skipping unless the stylus has been very carefully placed to compensate for this. Restoring U-S cylinders is very tricky. To get the best transfers of Blue Amberols on an Archeophone the machine has to run at 1/2 speed or less so the stylus doesn't bounce on the record's irregularities, then the transfer speed is doubled to bring it up to pitch without flutter. That doesn't happen (or as noticeably) on a well-restored 4-minute acoustical phonograph. PC

Matthew:
You probably have not seen this before, but we have discussed this in
the past. When you play a record on an old acoustical phonograph you
are not playing the record, you are playing the phonograph. The horn
resonances and reproducer characteristics overlays the distinctive sound
of that machine on any and all records you play on that machine. If
you want to hear what is on the RECORD, this is not the way to do it. A
modern electrical playback is the only way to do it.
Consider it like this: when I was a teenager a neighbor was able to buy
a mint condition Model A Ford. We had a blast riding around in it
occasionally, but we did it to ride around in an antique car. If we
wanted to actually go somewhere, we used a modern car. Sure, if you
want to get a kick out of playing your own phonograph, go ahead and do
it -- but remember you are playing the machine, not the record.
Now, as for the care of your heirloom records, the reason why the
records collectors find are not usually in mint or even E+ condition is
because people played them on acoustical machines -- not because they
WANTED to, but because that is what they HAD. They wore the records
then, and especially if the reproducer has not been repaired, they will
wear the records now. If you want to keep the records i the condition
they were in when you got them, don't play them on the acoustical
machine. Play junkers on it -- sometimes worn records sound less-worn
on acoustical machines. Occasionally play something you want to hear as
it sounded back then on the machine, but unless it is a common records,
don't do it too often. And, of course, used a new needle EVERY TIME,
and NEVER, EVER, turn a needle in the reproducer, or use a needle you
found loose in an old machine.
You don't say what your machine is. Unless it is an
Orthophonic/VivaTonal, or some other post 1925 machine, it was not meant
to play electrical recordings. The machines that were continued to be
made in India, USSR, China, etc, WERE meant to play electrical records
-- which is why Crapophones can sometimes sound great -- but a
pre-electric machine was not meant to play electrical recordings, even
late Chinese records. As for your specific question, I would never,
ever, play a Bluebird or any other 1930s record on an acoustical
machine, even an Orthophonic. They also were obsolete by then.
Over the decades I (and most of the rest of us old geezers) have learned
that there are three kinds of collectors: 1) record collectors who might
have a few phonographs just for the hell of it (but don't really care
that much about machines), 2) machine collectors who have a few records
just so they have something to play on their phonographs (and mainly
otherwise don't care about records at all), and 3) collectors who have a
fair amount of both machines and records, appreciate them both, and
therefore don't abuse their records by overplaying them on machines
except as demonstrations. I actually had a type 2 collector say to me
that he saw no difference between different records, but that the shelf
full of seemingly identical Columbia cylinder machines were fascinating
because some had three motor mounting screws but the next one had four,
and other such minor production-line changes. He saw no value in the
wooden crate of mint white-label Zonophone single-sided test pressings
other than he could sell them to Zonophone machine owners who didn't
care which Zonophone records they put on their machines to display. He
saw no reason to make a discographical listing before scattering them to
the winds to be worn out by Zonophone collectors.
I hope you understand what I am saying and I hope you are a type #3, or
maybe a #1 like me and most of us here.
