Sutherland PhD Issues

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.

WRT why expect other components to be the cause--the most natural first assumption is the assumption he made--the thing is supposed to sense a signal, maybe there IS a signal. Does it happen with nothing connected? No. Your suggestion about where to disconnect makes sense too.

Thank you folks.
As I have earlier explained, the Unit does apparently shut down without Phono Cables being hooked to the Unit, so this is what sounds strange to me?

As Tarsando states, this could possibly be a cause of RFI, maybe due to a poory shielded Cable, faulty Roneram, or Cable Wiring, or I even thought a fault in the Sumiko Bluepoint 2 Cartridge itself?

Is it possible for the Bluepoint (or any other MC Cartridge) to be emitting some signal while it is not in play, and the entire system is shut off?

Perhaps a dumb question, I know, but I reckon if one doesn't know, then asking is not perhaps so dumb after all.

Yes, Chad at Acoustic Sounds has responded to my queries, but gives pretty much the standard procedure of making adjustments to the Sentry Pot, and this has been tried to no avail. Mark
