Description The SP10 started life in 1970 as a servo-controlled motor unit designed for studio use. In 1975 the much improved SP10 mkII (1975-81) was introduced with Quartz-locked speed control and external power supply; this is the version which found its way into many studios, replacing ageing Garrard 401s and the like. The unit was also made available to the public as the high-end SL1000 mkII system which included the SH-10B3 Obsidian base and EPA100, and later the EPA500 tonearm.

The dynamic balance tonearm has been known as one that has an advantageous construction in providing high tracing ability, preventing skating, etc, tone arm designers have tended to underrate it because of problems such as the need for a spring, etc for application of stylus force and resultant increase in mechanical friction resistance.The GST-801 was the first dynamic balance tone arm that has successfully solved all of these problems by introducing a contactless stylus force application system. This Lustres unique variable magnetic flux type stylus force application system is a magnetic contactless system of compact and simple construction using a rare earth magnet.Features high Precision radial bearings.SpecificationsType: Magnetic drive dynamic balance typeBearing: High precision radial bearing x 4Arm pipe: Stainless steel pipeEffective length: 240mmOverall arm length: 337mmArm rear length: 80mmArm height adjustment range: 41 to 71mmOverhang: 15mmStylus force control range: 0 to 2.5gCartridge weight range: 13.5g to 28g (including headshell) On Jan-24-24 at 13:55:17 PST, seller added the following information: The video depicts the tonearm in use and is intended for that purpose only.
