Tonearm Dynavector DV501 Bi-axis tone arm Dynavector DV501 designed on the same theoretical base of DV505 which are recognized and appreciated highly for their outstanding performance and thus given the Design and Engineering Award at C.E.S. Chicago 1977. The DV501 tonearm has been awarded the similar prize at C.E.S. Chicago in1982 for its highly advanced technology. DV501 is a specially designed tone arm which can reproduce the signal on a phonograph disc without influence caused by any disc warp. In order to perform its unique specifications including bi- axis inertia separation to vertical and lateral directions, the DV501 has a more complicated structure compared to conventional tone arms. The DV501 arm is designed to be maintenance free. It will give long and reliable service, but should be treated with care and kept as dust free as possible. The DV-501 model was introduced in 1982, it's lighter, stiffer and simpler than the 505 or 507 models and does not use the spring loaded VTF and Antiskate system that the others have. To some, the 501 is the best of the bunch. And nota bene you can download the manuals for the 501 and the 505 from the company in a PDF format. This tonearm for sale is in perfect working condition. The wiring connection is state of the art.
