An answer to my original question ? Buelller........Bueller.......Maybe you should write some vintage enthusiasts, such as Art Dudley w/Stereophile. You need someone really familar with old mono carts, which isn't exactly mainstream, even for vinyl enthusiast audiophiles, evidently. I'm a bit of an anachronism myself--big band enthusiast since 1965, grew up in a house with a big tube Zenith radio/78 rpm record player. I'm 63, have been at audio since I was 18. My phono stage and line stage are both PTP hand-wired all-tube units. I have at least 80 mono LPs ranging from the '50s (Belafonte's "Calypso", RCA Ortho-phonics, etc.) to originals from the '60s to Prestige and Riverside mono jazz reissues.
And yet I have absolutely no knowledge of pre-1962 mono cartridges.
