Sutherland PhD Issues

I'm starting this thread up again here in the analog forum, rather than pre-amp to garner more folk's input about this issue, in which a friend 1/2 way around the world is having.

He notes that he is still having issues with auto-shut down with his Unit, and that when he unplugs phono cables from the Unit, only then will it go to sleep.

His Cartridge is the Sumiko Bluepoint 2. My question is, doesn't this sound like it could perhaps be an issue with the Cartridge itself, or perhaps Tone-Arm-Phono Cabling? Could these components still be sending signal to the Sutherland, even while not being used?

Neil, and you other good folks here, your input would be deeply appreciated, and desired, thank you, Mark

Could they be picking up RF?

This is a feature of the Sutherland so why expect that other components are the cause? I mean, this is a battery powered component that has a device which is supposed to shut off the drain when no current is flowing. Have you had your friend try (carefully) disconnecting the leads at the cartridge instead of the at the phono cables? If that leads to the same results it has to be an issue with the current sensing circuit or the circuit that is supposed to open the connection when no current is present.

God forbid you should ask directions. How 'bout asking Acoustic Sounds, their distributor? Sounds like a defect.
