While the Oracle's detachable arm-mounting plates make arm-swapping relatively easy, the nature of the mounting plate and the way in which it's fastened to the subchassis (round, in a round holder) means that precise and repeatable alignment of the arm is not simple. It's possible to set most cartridges with their back ends just below the level point, but not by much. Those who like to tweak VTA for every recording will love the Graham's calibrated scale, but may wish for a bit more available downward adjustment range in the arm on the Oracle. (Oracle is now able to provide mounting plates suitable for the Graham arm.) I should also make one other note concerning the Graham arm on the Oracle. Now both halves of the plate could be fastened to the subchassis first, following which the arm could be mounted on the top plate. He also furnished the longer arm bolts needed to reach these threaded holes. Bob Graham modified Oracle's SME mounting plate (which uses the same cutout as his arm) by providing additional threaded holes in the bottom of the plate to accept the arm mounting bolts. Personally I think this one of the most important turntable designs ever.Solution: contact Graham Engineering. The original Pink Triangle pioneered the use of an acrylic platterĪnd a DC-motor located on a lightweight aerolam suspended subchassis. Premiere with SME arm, a top-end version of the Delphi MkIV The Delphi is a trueĭelphi MkI with Fidelity Research FR-14 and Ortofon MC-25FLĭelphi MkI with Perfection Audio modifications and Grado arm Together with Michell the first to combine a pendulum-type TX-1000 in a rather exuberant system with among others a rare gold-plated 1000ZXL cassettedeck and the complete model 1000 DAT system. However, most people seeing these constructions for the first time react with saying 'wow'. Both arms could employ viscous damping (SME and Graham have this too :-), and the platter actually existed of a thin metal plate supporting a very thick and heavy rubber mat.īoth the big Nak turntables employed a record-centering platter It could be had with two arm versions: one quite conventional, the other without a real arm tube, but with a long narrow piece of printed circuit board connecting the headshell to the bearings (seen here). This was a very cheap turntable, made in Czechoslovakia, and yet it had a reputation for good sound quality.
