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

Geesh!!!
I'm very sorry folks for my typos in my last response.
I'm a superb speller, but a poor typer at times.

That should've read "A poorly shielded Cable", and/or "Faulty Tonearm, or Cable Wiring".

And as I had first suspected, a faulty Sentry Potentiometer on the Sutherland PhD. No doubt a $3 part on a $3,000 Unit, which could easily go awry.

Maybe a "miracle shot" of DeOxIt might do the trick?
It wouldn't be the first time, DeOxIt had come to the rescue! lol This stuff saved my own Cal Delta Transport a few months back! Mark

Many thanks to you and the others on this thread. It was a RFI problem. I replaced the phono cable from the TTie Clearaudio Emotion with a Cardas Golden Cross and viola the Phd has started shutting off even with the CDP playing. Something that never happened earlier.
Many thanks for all the help and support.
Cheers
Hello Piper/All
I've been helping "Sunny" try to weed through this problem, as he recognized I was another owner, and would perhaps understand the use of the Sutherland Better.

Of course, I'm no electronics technician by any sense of the term, , but the first "aha" came when he mentioned that the Unit did shut down without Cables hooked to it. I then suspected another cause, other than a fault of the PhD.

I wouldn't suspect a poor interaction between the Sutherland, and any of the Clearaudio Tables per se, as another friend of mine is using a Clearaudio Master Reference Table with his Sutherland PhD, and has experienced no such problems.

I reckon these conclusions-cures in which we have arrived at, clearly show-proove just how important a good shielded Phono Cable is, versus just a standard IC, no matter how high the Quality.

Thank you all again folks for your input. Mark D.
