Graham Phantom II 12" - dimensions and overhang

Hello guys,

I come from Europe and recently purchased Graham Phantom II tonearm with 12" armwand.I was missing specs for 12" armwand (in manual are specs for 9" and 10"),so I emailed to Bob Graham and asked him for specs for 12" version. The answer was,that 12" version should be adjusted same as SME V 12". Bob sent me document with SME dimensions as well.

So regarding this document specs are Leff 308,8, overhang 13,2, mounting distance ( Pivot-Spindle) 295,6.
To adjust mounting distance is easy using any quality protractor. I used Acoustic Solid.

So with mounting distance adjusted to 295,6,here comes the thing.
I should set overhang to 13,2 regarding to specs for SME V 12",but simply

Hi

I am dealing with similar issues after upgrading our 9" Phantom to 12" Phantom II supreme. We needed the 12" arm wand for the new TTWeights Momentus Duo Drive table we just got in for demo and sale, which has an outboard arm pod.

I am ordering a new Mint LP protractor for the 12" arm and this is the info I got back from Yip atMint LP. The numbers are in mm. and recommend the Mint LP unit highly. The one I had for the 9" version worked extremely well.

"For the 12-inch Phantom tonearm the spec is totally different:
295.6/308.8 Mounting Distance/Effective Length."

Hope that helps.
