Heavy sub weight, OP-1200-SPU If you ask record enthusiasts, "What do you think of Ortofon?", most people will mention the SPU series and Concorde series. In particular, the SPU series is a living legend that continues to be loved by everyone even today, more than 60 years after its birth. We want more people to enjoy this SPU, which is a symbol of Ortofon. With this in mind, Ortofon has created the sub-weight OP-1200-SPU to use SPU in the SL-1200 series. The tone arm installed in the same series has a distance between the stylus tip and the head shell connector of 52 mm, the same as the SPU, and has a wide range of weight that can accommodate large (heavy) cartridges. It is compatible with the series, and is easy to operate and set up, so it is the best partner for many people to enjoy SPU. We sincerely hope that this Subweight OP-1200-SPU will be of use to you as an entrance to SPU sound. [Notes] I. Of the SL-1200 series, the first model's arm weight shaft does not have a mounting screw hole drilled at the rear end of the arm weight shaft, so it cannot be used. Also, it is not possible to install other SL series tonearms that do not have an M4 sub-weight mounting screw hole at the tip of the weight shaft. II. When installing this product on a player or tone arm other than the SL-1200 series (excluding the first generation model), please refer to the spec data of the device to which it is installed and use your own judgment. III. The counterweights included with the SL-1200 series tonearms vary slightly in weight and size depending on the model. Although we have added some leeway to the weights for cartridges listed in our published spec list, please consider these values to be a guideline only.

Two-piece high-precision brass cutting weight The biggest feature of OP-1200-SPU is that it can support a wider weight range than the sub-weight SH-1200W-S, which was once produced as a genuine product. This makes it possible to use SPU GTX series (38g) and CG25/65 series (37g), which have heavier weights. In addition, by making the weight body into a two-piece brass cutting machine, it is possible to maintain the accuracy of the weight's weight while also being compatible with the SPU Synergy (G shell model, weight 28g), which is the lightest in the SPU series. Among the two-part weights, when using only the main weight, the corresponding dead weight including the head shell is 28-32g, when the additional weight "small" is combined with the main weight, it is 32-36g, and when the additional weight "large" is combined with the main weight, it is 36-32g. Cartridges up to 38g (all approximate values) can now be used. This product was developed with the use of our SPU series in the SL-1200 series in mind, but the weight of the cartridge body and head shell is similar to that of the SPU series (for example, Ortofon's MC Diamond and LH -10000, weight of about 33-34g). II. The thin shape of the OP-1200-SPU does not touch the dust cover except for the innermost circumference.The OP-1200-SPU has a tonearm that does not touch the dust cover except for the innermost part. It has a thin shape with a narrow installation depth. We also considered keeping the distance between the pivot part, which serves as the fulcrum of the tone arm's operation, and the center of gravity of the weight as short as possible, resulting in a disc-shaped sub-weight. This product does not come into contact with the dust cover during normal music playback using the SL-1200 series, but due to the installation of the dust cover and when playing discs with a small diameter label such as SP discs, the needle of the cartridge may come into contact with the dust cover. When the tip reaches the inner circumference close to the label surface, the side of this product may come into contact with the side of the dust cover of the SL-1200 series, which may put excessive stress on the stylus tip and record. . Therefore, if the cut of the sound groove on a record is near the innermost circumference, or if there is a possibility that tracing will be performed to the innermost silent groove without raising the needle immediately after music playback, be sure to cover the dust cover. Try playing with it removed.
