I found this thread just today and don't know if you are still looking, but the inertia (which assume same as torque) is listed as 1.2kg/cm. I have just bought a TTS-8000 and a TTS-6000 and also have a Sony PUA-1600L. It will take a while to get them set up as I need to get or make a plinth first. I will report findings once done.
