Default a bit OT: Will a 78 rpm record damage a normal stylus?

Of course the obvious thing to do is take a note of the titles the label
details and the number of the disc. The chances are that somebody has
already done the conversion and restored it. You would be surprised at what
a simple search can turn up. I had a horrible recoding from a 78 of Petula
Clark singing make Way, a very well known song with many different lyrics,
and it was dire, but a quick search found it already converted pretty
cleanly and even available from Amazon to stream. It was on what I used to
joking in latter years call the dead parrot label, called Polygon.

Weirdly I found an old 78rpm record of Harry Gordon stuffed under a
hedge
this morning whilst out for a run.

I have a conventional record deck and wondered about playing it once

rpm and recording it and then speeding up the playback.

Would this work?

For some version of 'work'...

If you don't mind the risk to your stylus, you would probably get
something out of it.
your 'LP' stylus will be sized for the 'microgroove' of a 33rpm record
(hence the phrase,
when the new Long-Playing technology came along). So the stylus will be
swamped
in the groove of the old 78. If you just have a cheap ceramic
cartridge(*) then I'd
probably give it a go regardless.

The other thing you will have to bear in mind is that the frequency
equalisation that
was applied to 78s was not standardised. This later became the standard
'RIAA' equalisation
that your record player electronics will implement, to a greater or
lesser degree. There were
a whole load of different curves defined before that - there are charts
available.

If you can use an audio editing program (Audacity, Adobe Audition...)
then you could apply
a combination of the LP RIAA curve and a 78 curve and get a better
result
(highs and lows balanced). It would be an interesting little project.

(*) some of these have a flip-over stylus, one side for LP, one for
78s. If you have a
moving magnet cartridge, you might take the risk. If you have a moving
coil cartridge,
then (a) you will know it, and (b) I wouldn't try any of this.

Cheers. I did think about buying the "cheap and cheerful" double needled
ceramic cartridge but not sure how it will play with my AV amp.

We already have to have a small pre-amp as there's no phono input on my
amp.


The ceramic cartridge (eg, as found on the classic Garrard, Collaro or
BSR autochanger and fitted with a flip-over mechanism for swapping
between vinyl and shellac styluses) doesn't need a pre-amp stage. You can
just run the output direct to your soundcard input.


You might loose quite a bit of bass depending on the input impedance. I
guess an sound equaliser can make up some of the loss.
