I am the original owner of this tonearm which was purchased in 1983. This is one of the classic tonearms from that era with a tri-pivot lateral balance system. Tracking force is a breeze to dial in. It has the detachable ZPZ (zinc alloy) headshell. It saw light use for approximately 10 years and has not been used since. It is in good condition except that the arm lifter doesn't always descend properly. It lifts correctly but sometimes needs a "nudge" to make it descend (it may need new internal grease). There are some minor screw scratches on the headshell. There is some clay on the undersurface of the headshell for increased dampening which can be removed if desired.
