A lot of those 78s had some weird, or even, none, equilazation, these go back to the purely mechanical "Victrola" days with wind-up turntables, and the big "flower" horn, and those wonderful steel spikes or cactus spine needles vibrating the thin diaphragm, whch the "horn" then (sort of) amplified, with a frequency response between 200 Hz and 3 KHz, most likely.Most of that would be covered up by the frictional noise, anyway...
schrch, schrch, schrch.......
Use of a decent modern cartridge and stylus on a "stone cake" would probably present a serious hazard to the stylus's well being... :o
"Stone Cakes", I like that Yellow_Light_Colorz_PDT_04 Yellow_Light_Colorz_PDT_03 Perfect description for those things.
Then there were the 16 RPM records, usualy recorded speech, rather than music, as the frequency response wouldn't reach too high, maybe OK for the Warsaw All-Tuba Polka and Marching Band, perhaps Yellow_Light_Colorz_PDT_04
I have some glass 16 RPMs of an economics lecture at Harvard University, made back in the late 1930s or 1940s, the weird part is that they start in the center and work out towards the edge. Truly riveting listening.... Yellow_Light_Colorz_PDT_50 Yellow_Light_Colorz_PDT_26 Yellow_Light_Colorz_PDT_27 Yellow_Light_Colorz_PDT_22
Then there were the smaller diameter yellow plastic "kid's music" 78s which usually wore out about the same time that the heavy tracking steel "dart" needle did. :o
