Grace 727 or 747 tonearm setup question.


Hi, I picked up a Grace tone arm I think it is a 727 or 747 model tonearm for free. It looks just like the 727 literature sheet that a friend had including the removeable headshell. The sheet doesn't have the information I need. I will mount it on an Oracle Delphi table. My question is what is the proper table spindle to arm pivot center distance. Thank's to anyone that can help.

The Rega Planar 2 I bought 13 or so years ago had a 747 arm on it (I still use it!) I measured the distance as 8.75 inches exactly. Try that distance. It always performed beautifully. Good luck with it.
I have a Grace (707?) on Delphi, still sound pretty nice. Could I add one question to thread. I am thinking upgrading the phono cable, mine is maybe 20 years old now. Could anyone suggest one cable <$200. Also I am not sure what Grace's pin layout is, not open it for so long. Thanks for input.
I have a 727 on my planar 3 tt, and I still have all the original documentation for it. I'm at work now, but if you'll wait until this evening and email me (mstamm@earthlink.net) I'll try to give you the info you need.
