Has anyoe had problems using the mint LP tractor

Wes, once you get sorted out with a suitable well lit work area.
Have on hand several tools that you think may help during set up, read through the MintLp threads for suggestions.

However what works well for others especially optical aids may not work for you, some experimenting has to be done on your part.

I give the instruction manual for the Mint tractor highest marks, follow it step by step and learn to have PATIENCE.

In the end hopefully you will be thrilled with the results of a highly accurate catridge set up and just think, one you did yourself.

I am a novice at best and each time I checked set up of my cartridge I further dialed it in with notable improvment.

What better way is there to know your turntable.

Jimjoyce my vision is good and I guess my vision would fall into the category of normal.
However attempting set up with the Mint arc protractor without the use of a magnifier of any kind and expecting and getting highly accurate results would be an incredible fluke.

The Graham Phantom jigs are exceptional and tower over many other tonearm manufactures supplied set up jigs.

"Careful" set up using this arc protractor from MintLp has a noteable repeatable improvement over the superb Graham jig.
Once you hear the results there is no going back.
