After 50 years of designing and building world class turntables, Jochen and Dirk Räke, who has steered the fate of Transrotor for the past twelve years, made the decision to design and build their own Transrotor tonearm. With the immense practical experience, knowledge of turntables, setup and access to the most modern production method the team set out to design the new tonearm. Besides having to meet the tight specification, the tonearm must offer ease of use and simple adjustment. After 2 years of development and testing, the TRA 9 is introduced.
The 9 inch TRA 9 arm tube is made of two different aluminum alloys, slid into each other, stiff and resonance-free. The aluminium alloy counterweight has interchangeable brass weights (depending on cartridge weight). VTA adjustment is done using two screw-in adjustment screws to lift the tone arm in parallel. Magnetically adjustable via a fine thread, center adjustment 1.8 g (gram) (red line) for anti skate. Inner wires are pure silver cable (4x Seven Stream van den Hul), oxygen free insulation outside and inside with silicone tubing, protected and damped, connections with silver solder, system connection cable plugs silver-plated. Connection cable are pure silver cable (same material as inner cable), oxygen-free insulation wit RCA or XLR connectors.
