In Reply to: RE: There's NO SUCH THING as a "stereo" stylus posted by Newey on September 18, 2015 at 20:43:09
I agree that a stylus is not mono or stereo. It was a poor choice of words, although I would not use a conical or an elliptical stylus on a 4 channel record (QS or SQ) because it would not properly track the high frequencies needed to get the full signal. I have hundreds of mono records and am will aware of mono microgroove records, and own quite a few. I own some of those original mono cartridges.
I would expect that too small a needle at low tracking fore would slam around the 78 grove, but I don't have proof. You are welcome to try on your 78's. Mine will only be played with the proper sized needle at the high tracking forced required to track properly (depends on the cartridge).

If you use too small a stylus on shellac 78s, even after one play, I guarantee you will rub off black crud from the chafe which will deposit on the stylus tip.
Even a 2 mil stylus, called the "universal size" but known as the compromise size, can easily damage shellac discs designed for 3 mil styli. Some cartridge and stylus manufacturers offered 2.7 mil, rather than 3 mil, as replacement styli so we could "avoid the worn, scratchy groove areas" affected by the too typical worn needles used in the "good old days."
If you research the stereo preamps of the early stereo era, 1958 to 1962, you will see that some classic stereo control units did not offer a summed L+R mono choice in playback. Instead, they offered L or R channel mono playback to effectively offer a way of reducing worn groove noise; using only one groove wall. This is a most unfortunate historical event, as classic preamps like the Mc C-20 and Pilot 210, as well as more than a few others, would require a modified/rewired or replaced switch to accommodate a summed mono signal. Many stereo preamps also avoided and still avoid offering "stereo reverse" as a "mode" option. Oh well....
