Graham Phantom Supreme?

... wonder if the new adjustable jig is configured for each tonearm length ?

No. It is only right for 9"".
When you use it for 10" or 12" the alignment is wrong, but normally you can hear that in 5s.
For these lengths you should use a seperate alignment System.

The alignment from the Phantom is pretty good. Here is a pic from the
bubble position

and the matching needle position

I like that fat counterweight. Looking forward to the upgrade, whenever that actually happens. I'm on the list but was told recently that it won't happen before 2012. Mr. Graham is behind, I hear.

Why would Bob Graham knowingly produce an alignment jig that is off for the 10" & 12" arms ? How much error are we talking about ? To my ears, the alignment sounds perfect...No audible distortion through the lead out groove. Too bad Graham didn't put a detent on the center of the pivot cap so that I could use my feikert. Anyone have an idea how to measure for the exact center point so that I could make my own detent ? I am going to inquire with Graham directly about this.

Dear Hiho, it is the off-set angle at the headshell mounting area. The problem here is, that the off-set of the mounting area is too large for the 10" and especially so for the 12" arm wand.
Resulting in additional and unnecessary breakdown torque as well as in an odd position mounting of the respective cartridge.
In an uni-pivot like the Phantom the bearing has no off-set - just the mounting area has ( here off-set is a function of the geometry and effective length ). The smaller the off-set angle is, the smaller the breakdown torque is.
That's one of the reasons why longer pivot tonearms do sport less skating force.
Hope I am not too obsessed with minute detail here ...;-) ....
