Re: [ARSCLIST] 16" transcription player on ebay
Doug, LP is a term associated with commerical records. 33.3 rpm goes
back to the late 1920s, but for picture soundtracks, not commerical records.
What you have is a transcription. Not a record intended for in-home use.
They were used by radio stations, but I think also for educational
purposes, hence the occasional school players that can handle such a
large disc. Anyone confirm this?
The way to tell what your record is - if the timing is available
anywhere, a 30 minnit side would be a microgroove. Most likely, since it
is red vinyl, it is later vintage so probably 3 mil, or a 15 minnit max
side. The other way - if your vision is strong enough, look at it. The
dif in a coarse and microgroove record is visibly apparent. Compare a 78
and an LP sometime.
You might check with the library at UW-Madison, in case they have any
thing else like this. When I was a grad student there, I never cam
across any. That was in the mid 70s.

I'm sorry, but it seems my technical in-expertise has muddied the
waters. I bought my first LP/Microgroove/33-1/3 record in 1958 when I
was in High School. Every 10" and 12" record I ever bought played on
the players bought at the time and since. Until this discussion, I
thought LP/Microgroove/33-1/3 records were all created alike and all
three terms referred to the exact same thing. Other than the "33-1/3" on
the label, I do not know if what I have is an "LP" or something else,
and I don't know how to tell what it is. I'm sorry if I used the term
"LP" incorrectly.
What equipment do I need to buy to make a one-time measurement (and
probably never use again) to determine whether this record has a 1 mil,
1.8, 2.1, 2.3, 2.5, 2.8, 3.0 mil groove or something else? I don't know
how to tell the difference between all these varieties.
In all the responses, no one has mentioned that they have ever
heard, seen, or read about in print of another 16" record produced at
UW-Madison. Is there anyone specific I should contact in the Oshkosh /
Milwaukee / Madison area that does have the expertise to identify
exactly what it is I have, and whether it is the only one still in
existence, however I doubt that it is? Thanks.
