Well, you can't use a DD reproducer on anything but a DD. You could use a suitable adaptor in place of the DD reproducer, however to play another brand vertical record on the DD machine. Diamond discs are not designed to propel the arm across the record. However if the machine is nice and level and the arm is very free swinging, it will work. I don't know if there is anything to be gained or lost sonically.

(J.M.J.) What would the pro and cons be regarding the playing of other company vertical records on a C-19 or C-250 machine? And what about playing DDs on any other machines that the sound box can be turned to play vertical records with a saphire stylus? Are there any possible damages to records to be done, or any real fidelty or presences increased especially if playing Pathe, Lyric, Okeh, or other verticals through the 250 horn? I would like to try this on my machines but am waiting for any advise. Maybe I am best to just continue to play records, as I have been, on the proper machines? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
