Graham Phantom question
« on: 6 Nov 2008, 01:30 pm »
Hi guys

This is my first post here,so please,excuse my English aa
Anyway,what i'd like to know is whether the Graham Phantom (when ordered with the sme type base)includes the sme type HTA adjustment or is it just a compatible mount?

thank you all  :thumb:

Hello and welcome to AC.

I don't have SME mount on mine (Graham mount) but I have a SME arm on another table.  Graham H(V?)TA adjustment is easier than SME's.  I wouldn't want the SME style over Graham style VTA adjustment.

Thanks for the reply Woodsyi

No,i wasn't reffering to the vta adjustment but to the hta (horizontal tracking angle).I have a sme v and since you have one on another table you'll know what i mean.It is the procedure where you insert a key in the arm's base and you adjust the geometry of the cartridge by moving the arm forward and backwards.I love this thing on sme arms since the most irritating thing is having to move the cartridge back and forth in the headshell to achive perfect geometry.hey,i'm lazy ! rotfl

I don't know if you can or not on SME mount.  Graham mount does not have that.  Fortunately (?) my arm mount is movable ijf  need to move my arm that way.  I don't see the point in moving the cart in and out.  Isn't there just one null point? :o

We all have to move the cartridge in-and-out on setup,to achive perfect geometry.I am sorry,i don't know how to say this in English.It has something to do with the cartridge being parallel to the record's grooves etc.Anyway,to achive this (and this is something you should know since you allready own a sme arm)you simply fit the cartridge on the tonearm,then you place a protractor on the spindle,then you lower the arm so the tip of the cartridge goes inside a small hole on the protractor and by using a small spanner,you move the arm forwards or backwards until the arm/cartridge is parallel to 2 lines on the protractor.I am sure you know what mean.it's my limited english that are fault here.Not 100% sure but i believe the procedure is called "azimuth" adjustment ?

If your armboard is fixed and there is no wiggle room in your headshell, I guess you will need to be able to slide the arm up and down the line.  This is Azimuth as I understand it:  Azimuth is the side angle of the needle in the groove.  You want it to be perpendicular to the record to get the best stereo separation.  Phantom uses Magnaglide that uses magnets to "tilt" the arm on a unipivot.  It's quite effective and easy to adjust.  SME on the other hand does not give you an easy way to adjust Azimuth.

BTW,  This is probably the best protractor if you want to go this far. http://www.mintlp.com/best.htm

HTA? oh ok I get it. It's the SME's overhang adjustment right? The modern SMEs have holes instead of slots to mount the carts on so the only way to adjust overhang on a fixed arm board is to slide the entire arm forward or back. In the Phantom, and almost any other head shell or arm wand I've seen, overhang is adjusted by moving the cartridge forward or backward in the slots provided for the mounting scews.

So no the B-44 doesn't have HTA just plain jane mounting slots on their wands only a compatible mount.

As a result set up procedure is quite different. After establishing the proper pivot point using the little white cap that goes on the spindle and mounting the arm on the arm board or arm pod, the wand is removed and it's the cart's turn to be mounted. The cart is then aligned using the supplied alignment tool so the stylus is positioned in either the L1 or L2 position with the cantilever parallel to the vertical line in the case of the Phantom 1 or between the two points in the Phantom 2. Screw the wand back on, adjust VTA, VTF, Azimuth and Anti-skate and you're good to go.  :D

I've never had tracking or alignment problems using the supplied tool but there's no harm in trying other protractors. Just make sure you get the pivot point dead center.
