RE: 78 rpm stylus for 33 rpm records? Can it hurt?

Hi Mr. Blue Sky,

What we think of as a "modern" microgroove 33 1/3 RPM Lp started after WW2 and at first had a 1 mil groove. About the time stereo came out the groove width became 0.7 mil.

There were 33 1/3 RPM records with close to 2.7 mil grooves used for radio transcription and movie sound.

As John said you will lose high frequency response with an excessively large stylus and may have tracking issues. I would guess there will be record damage.

Does it work? Yes, of coarse you can do it, but not with my Lps.

There were even budget 78 RPM 7" vinyl records made in the '50s with what looked to be microgrooves. I believe a common label was Bell. They were largely kid records and no doubt were played on old 78 players, some with steel needles. There was nothing on the label about stylus size. Just a note that they contained as much music as a standard 10" 78.
