Need help with Sutherland Ph.D. phonoamp


I have a borrowed Sutherland Ph.D. phonoamp home to audition for a week. Can anybody help me with it:

What settings do you recommend for a Koetsu Black...resistive loading and gain?

Also, about three minutes after startup the yellow light comes on and after about five minutes it turns off. It will only turn on when I use the cleaning brush against the needle. What gives? Are the batteries low? (The red lights flash momentarily just before it shuts off.) It worked fine for several hours last night just after I hooked it up.

Ed,
No. Indeed I found it interesting and was just what I wanted. I guess I didn't quite do the right search of the archives before I started this new thread.

Course, the famous lack of documentation which "comes" with Koetsu's doen't help.
Many thanks,
John
My post indicated 100 Ohms, as in "one hundred Ohms", not 100k (one hundred thousand) Ohms or even one thoussand Ohms). Anything higher than 100 Ohms for a Koetsu does not load the cartridge sufficiently for good, warm full sound, but instead tends to brighten up the cartridge, often to compensate for too low a vertical tracking angle. The correct way is to use 100 Ohms and adjust the VTA to obtain the best frequency and focus balance. Other Koetsu owners should also contribute to this thread but most will tell you 100 Ohms is the correct load. I have an Urushi and Krell KPE Reference and ran extensive tests to determine that 100 Ohms was best. Also, check Koetsu's website (actually Musical Surroundings):
http://www.musicalsurroundings.com/koetsu.html

There you will see the load range as 5 Ohms to 100 kOhms.

Thanks Steve. Sorry, my mistype. I need to engage my hands BEFORE putting my brain in drive. Ed

Thank you, Steve, for the reduction in entropy...I figured it was just a typo but your concern is very much appreciated.

Thanks also for the new thread to puruse. In it, Albertporter says that he has found 1000 ohms to be the magic loading. Perhaps this is a result of using the Io which some consider somewhat dark. Just speculating. Hope he weighs in on this.

I get the message that I need to try some different settings and decide for myself.
