Having just read a test report regarding the Thorens TD 2035 claims it runs slow. Hifi News and Record Review claimed the TD 2035 ran at 33.01(-0.98%). Would this be a motor or power supply issue? Is the 6kg platter to heavy for the motor? Could improper set up or dirty electricity be a factor? You would think an upper level Thorens deck should run at or near exact speed.
