  • High Tracking Force Phobia?

    I have an opportunity to buy a EMT OFD 15 mono cartridge for my EMT 997 tonearm. The tracking force needed is approaching 5 grams. The stylus size is appropriate for todays new reissued mono records.
    EMT can no longer make this cartridge, so they are hard to find in the condition I can buy it for. Low hours, nice and clean.

    Should the high tracking forces needed, keep me away?

    what is the stylus profile? spherical, elliptical, etc?

        that's worst case because you don't get a lot of contact with a spherical stylus. Ive seen many new carts that run at 3g max but 5g is 66% more, I don't know.

          I would have absolutely no qualms in playing even the rarest of records on my OFD 25. As for modern re-issues,if I even suspect the LP may possibly almost be mono I'll play it on the OFD 25,I so love the big robust bass, stunning trebles and explosive dynamics this thing can create. I have yet to notice any damage or hint of mistracking on any album.

          BTW for absolute best perfomance the OFD must be mated to the correct transformer. It sounds superb on the EMT 997 but for bone crunching bass ,even more dynamics and almost frightening treble power try it on an FR64S-at 5g of course.

          Here is mine residing on a modified Grace pro arm. Note the double counterweights needed to balance the beast:

            What transformer do you use?

            Nice table, what is it?

            At the time of the OFD purchase Hans Michael Fabritius strongly recommended the use of a correct transformer. He supplied a suitable one. I can not remember but seem to recall it has a 0.9:1 ratio.

            The table is a non commmercial product developed,built and used extensively by the South African State Broadcaster until the late 1970/early 1980s. It is officially called the SABC Mk 111 or colloqually known as the Doc Viljoen after its designer.
