SME 20/2 & Graham Phantom issue

Hi guys
I'm having an issue trying to setup the Graham's Phantom on the SME 20/2 (in place of the SME IV.Vi ): I cannot position the Phantom straight forward as suggested in the manual (due to the fact that the VTF adjustment knob of the Phantom does not have enough clearance (it touches the rear right post of the SME20 turntable). Did anyone have this problem when setting up your combo? I am wondering if i have to swing the arm rest inwards closer the platter, will it effect the accuracy of the arm's anti-skating mechanism?

The reason i asked is that with SME arms, it is crucial that the arm is placed in a particular position so that the edge of the headshell is about 53mm from the edge of the platter in order for its anti-skating to work correctly, and in this position, the arm-rest is not pointing forward.

Would this be the case with Graham's Phantom too? Would the anti-skating mechanism NOT work correctly if the arm is not pointing straight forward in its arm rest???

Thank you.

I have a problem w. the AS weight hitting the outer ring if I use it.

Jaeswei,

I would love a picture of your setup to see what you did.

Rlawry,

I photo of the different base would be great. I know I am jumping in on the thread but curious as well.

I have been analyzing the Phantom and the armrest position appears to effect the antiskate start point of the tonearm. So it does have an effect. I have 3 arms so I can use the either of my other 2 arms w. the Phantom armrest moved aside. I just need to readjust the Phantom each time. I agree about using a longer armwand to allow you to use the outer ring. I wonder if it compromises the arm to some extent. I doubt it tough as my Schroder is a 10.5inch & the Ikeda is a 9 inch. There is an interesting write up from Frank Schroder re: arm lenghts elsewhere. He explains some of the benefits and compromises. One of the great things about the Phantom is that it is incredibly easy to setup.

Is the elongated version for the VPI the same? Do you use the spindle and the plastic cover to determine arm distance? Do you still use the setup jig to setup the cartridge?
