Re: [ARSCLIST] Advice needed on how to restore an old acoustic recording

I've mentioned it before but it bears repeating..Pathe type vertical cut discs (with the wider groove) play BEAUTIFULLY with a 2.0 mil truncated elliptical stylus. Unless the disc is badly damaged, I've found it will track with no problem with this stylus.

Edison, Brunswick verticals, Rishell etc. may do well with this stylus also, but I've found a 2.5 mil elliptical (Shure SS78E and good luck finding one of those) to be perfect.

.7 mil styli work best on 33RPM verticals (Muzak, World Program Service).

If you are bringing the signal from the cartridge to your computer in stereo, combine the signals in your computer program with the phase reversed in ONE of the two channels. There should be some way to toggle that choice. If you are combining them to mono before the computer, follow Dan Nelson's advice. There is another factor when playing vertical discs -- is the groove a needle-type or a sapphire-ball type. The books I just looked at do not mention which. If it is a sapphire-ball type, you might need a wider stylus such as the 4 mil truncated or even wider. Anybody else have one of these. Supposedly they are all of Henry Burr hymn on one side and a Hymn Talk on the other.

First question!!! Are you playing the disc as if was a lateral recording ? You need to modify the cartridge connections to play vertical recordings.
If you have not modified the connections then you must do that before you think about stylus.
I have played vertical recordings withe .7 mil lp stylus, 2.5 mil tuncated and 4 mil truncated depending which gave the best reproduction.
To modify your cartridge connections (put the two coils in series) use the left ground as ground. Use right + lead as the output lead. connect the L+ and the R- together/in series. This will give you a mono vertical output to your computer.
Hope this helps

Hi. I'm an amateur at sound restoration. I don't do
it as a profession, just as a hobby that I really enjoy.

I purchased a Rek-O-Kut CVS-16 turntable that will play up
to 16" discs, a Stanton 500 cartrige and two styli (2.75TC, 3.0E). I
transfer everything thru a flat phono preamp, and do all the restoration and EQ
in my software, DC7Live.
I'm trying to restore a recording from 1916. It's
on the Angelophone label. It is a vertical recording, seven inch, speech
only. I have several copies of the recording, but I think they've
all been damaged to one extent or another. I've tried playing them with a
2.75 TC diamond and a 3.0 E. The surface noise is quite pronounced. I
attached an mp3 of a very short segment of the recording to let you see what
I'm up against.
I don't have a microscope, and I don't want to
continue buying styli until I get the right one. My question: Would anyone on the list be willing to look at
and make a recommendation on the proper stylus to play these
recordings? I'm in New York, and I'd be willing to send the recording to
someone for evaluation and recommendation on what type stylus I should use. I
know it's a long shot, but I'd really like to do a good job restoring
these recordings. If anyone has any suggestions for a humble newbie, I'm

Thanks for considering.
Sincerely, Eric Hollis
