In Reply to: RE: 78 rpm stylus for 33 rpm records? Can it hurt? posted by coffee-phil on March 15, 2017 at 22:58:03
The spherical tip of the stylus is the only part that rides in the V-shaped groove. For a given frequency, the curvature of the groove-wall is smaller for a 33-rpm record than for a 78-rpm record. Therefore, a larger spherical tip can be used with a 78-rpm record. If you try to use a 78-rpm spherical stylus on a 33-rpm record, it will not be able to track the higher frequencies.
However, there is no sense in explaining this to you anymore. What you need to do is try it and you will understand immediately.
I had regarded you as one of the more knowledgeable people on this forum.
The question I was raising is whether the spherical tip of a conical stylus intended for standard groove 78s is indeed smaller than that of a conical stylus which is intended for microgroove Lps.
You apparently are not carefully reading what I wrote or not fully comprehending it.
Your responses have become somewhat insulting.

Is this a joke? If this is your question, then you are the one who can't read or even remember what you've written. The original post states that 78-rpm styli have 2.7-mil to 3-mil tips. You yourself wrote that microgroove styli are 0.7-mil to 1-mil. You know as well as I do that these are the radial dimensions of the spherical tip of conical styli.

Really? Well, this is my last response so you should be happy.
