Yep, sorry guys, a quick Google around seems to show Rega and Systemdek recommend high viscosity gear oil... I sit corrected (as I'm not standing.) Must admit that the AR XA has quite high clearance between spindle and shaft. Don't know about Rega etc, but I wonder if clearance also comes into the equation as precession is what kills reproduction. I also wonder if in the case of the AR tables, low torque motors require lower viscosity lubrication so as not to overload or slow the motor.
