Graham Phantom I tonearm


Hello everyone ...
I need help ...

Recently I bought a Graham Phantom I tonearm, supposed to be in excellent condition, it happens that I was deceived and the arm was completely defective ... cueing divise system not working properly, had no fluid was completely dry, the headshell was glued to the armtube and is twisted to the left side of about 4mm...
I personally fixed the armlift, I used SME fluid to repair the armlift, and already buy a new Graham Phanton II armwand...I thought I had solved the problem ...but now I have another problem...
I installed one of my catridges, a Transfiguration Phoenix.
When I put the arm around my Digital stylus force gauge to select the weight, for example 1.9 grs, and when I return the arm to the armrest position, and without adding any weight, I again put the arm on the stylus force gauge, always shows different values, example 1.95,1.98,2.00, 2.02 etc, as I said without adding any weight ...Anyone know the reason, or has gone through a similar situation, what can I do to solve this problem ...
I have a new Van den Hul Colibri Gold Reference XGP to install, but with these differences in weight I will not risk it...
Living in the Azores, and I'm not very interested in sending the arm to Graham, for now ... I am very grateful if someone help solve this problem ...

Thank you very much.

I have had trouble with digital gauges; I don't see how the arm could be changing so it may be the guage. Unless the counterweight has a little play in it; I have not had this problem with my Graham 2.2.
Why did you not send it back.
I agree with Stanwal. It's the gauge and not the arm.
The gauge is your problem.
How old are the batteries in your stylus gauge? You might try replacing them - - a couple of years ago I had a similar problem with my stylus gauge. Putting in new batteries solved it. YMMV
These digital gauges can make you mad. When you do multiple test, you have to place the needle always exactly at the same place,
You can put some fluid into the bearing, but you can also not do it. Don't worry about that. More important is, the bearing was protected with the plastic cap when shipped to you.
What scale are you using?
The error you are getting is only 0.07g, maybe your scale is not that accurate/reliable?

If your scale contains ferrous parts the difference may be due to magnetic attraction (due to the cartridge magnets).
To get around this you could use something like this.
It's not the digital gauge, I replace the batteries. I tested the gauge with my other arm's, VPI 12.6, VPI 12.7 and Tri-Planar Mark VII UII Ultimate model, the gauge works well.
Syntax,you must be right, the bearing was not protected with the plastic cap when shipped to me.The arm was not even packaged properly in the original box, was in an inverted position...
I am thinking to upgrade with the new Phanton II bearing cap...It may solve the problem...
