Technics SL J1 beautiful turntable, in very good condition, greased and cleaned, new belt, new capacitors on the power source and motor speed regulator. Some scratches on the lid. Speed selector is set on automatic, you can't switch the speeds from the out side of the deck, probably the technician didn't fixit properly when revising it, didn't bother to return to him, was scheduled for the next revision because doesn't affect playback or speed selection on any level. Ground cable (not original) included in the sell. Cartridge: Technics P30S (produced by Nagaoka for Technics) Stylus: Eps30cs very good condition Automatic speed selection Automatic disc size selection Skip Direct access Auto lead-in 2-speed search Automatic return Automatic stop Repeat Description: The SL-J1 was a turntable and one in a series of linear tracking turntables consisting of SL-J2 and SL-J3 manufactured by the Technics Corporation of Japan. The SL-J2 and SL-J3 had the quartz Direct Drive (DD) system, whilst the SL-J1 was belt driven. All of these turntables used the gimbal suspension linear tracking tonearm, which moves across the record in a straight line similar to the cutting lathe that produced the original master record. An advantage of this is that it eliminates tracking error and thereby distortion. In this design, a DC motor controls the movement of the gimbal suspension tonearm, and a microprocessor system that receives data from an optoelectronic sensor controls the motor. These turntables use the standard "P-Mount" plug-in cartridge connector system adopted by many cartridge manufacturers. This allows the use of a wide range of cartridges such as EPC-P205CMK4, EPC-P310MC2, EPC-P550, EPC-P540, and EPC-P530. However, for the factory-installed cartridge, the replacement stylus was usually EPS-30CS. The SL-J1 uses leading-edge electronic engineering of that era. For the microcomputer, they use the MN1420 (IC301), which performs all the housekeeping functions. These were in the category of general-purpose 4-bit single-chip microcomputers, with 1 Kbyte ROM memory space, that they produced using NMOS technology. For the tonearm motor drive and blank groove detection circuit, they use a dedicated integrated circuit AN6690 (IC401). The main difference between the belt-driven SL-J1 and the quartz-phase-locked DD SL-J2 and SL-J3 is in the wow-and-flutter figures. They rate the former at 0.045 % wrms, whilst the latter two are rated at 0.025 % wrms. However, a good working SL-J1 with a good motor and drive belt should perform just as well and many people should not be able to tell the difference.
