We have an Ortofon RS-309D 12" tonearm available for sale.
This tonearm was originally sold by us with a Thorens TD-550. It was setup professionally by Thorens originally.
Then we took it out of the table to upgrade for the customer.

*****
RS-309D 12 inch Ortofon’s D series tonearm takes analog sound reproduction to a higher level with highly configurable VTF options and a dynamic balance system for increased stability when tracking warps and other anomalies.

D series tonearms can be used for a wide array of cartridges, feature anti-skating control.

Features:
* Dynamic balance graduated vertical tracking force (VTF) control through a new spring design
* The new short wire spring, housed in the pivot case, eliminates unwanted vibrations in the tone arm
* VTF in the range 0-5 grams can be precisely adjusted by means of the supplied digital force gauge
* Anti-skate control adjusted by calibrated dial in the range 0-5 gram
* Tone arm height, and thereby VTA, is easy adjustable on the tonearm base.
* Detachable head shell and tone arm cable, with standard SME-type connectors

Tonearm is in great condition and works flawlessly.
MSRP is over $4000 CAD. Asking for $1600.

There is no box, and no tool because it came with the Thorens TD-550.
