Mint Tractor


I'm sorry, I apologize, please forgive me for doubting all of you who have told me of the need for the Mint Protractor. I got it today, and just did a quick check to find that the cartridge is indeed off set up with the VPI protractor that comes with the Supercout/10.5i. I read the directions and it is a very tedious, and slow going procedure, so I'll get back in a while and tell you if I hear any differences.

Pardon my ignorance, but can someone tell me how to purchase a Mint tractor?

Thanks!
Thanks, Sonofjim.

I do have Fremer's video - it's given me a good understanding of what's involved, how some things work etc, but I'm not yet at the stage where I'm going to tackle things myself. that being said, I can totally understand the benefits of that and acquiring the tools is the first step.

I'm sure I'll be watching Fremer's video several more times. :-)

I ordered a Project stylus force gauge from musicdirect.com; hopefully this will handle the VTF duties adequately (if not, please straighten me out).

I'll check VPIs site for the measurements and double check them.

Thanks.
I received my tractor this week and began the fun yesterday.

I had wanted to change my cartridge and was waiting for the tractor to arrive before doing so, but I first checked the overhang with the old cartridge and it was off by a few millimeters.

So I changed cartridge and adjusted the overhang as best I could; once I got the hang of using the loupe I was able to be accurate on the outside arc, but I can't seem to find an angle that allows me to see with the same accuracy for the arc near the spindle.

I briefly checked out part B. It took me a whlie to be able to 'see' the 'country road' the way I was supposed to, and I think I'm seeing it correctly, but it doesn't really look like the angle of the cantilever is off. I'm guessing from everyone else's comments that the chances of this must be mighty slim and that I need to concentrate more. I'm about to do that today, but thought I'd just throw this out there: did anyone find that they didn't need to do much in part B?
Small update: with fresh eyes I did see that the cantilever angle is a bit off. I find this part the hardest to determine because I have to use one angle to see if the lines are parallel and then tilt up a bit to see the angle of the cantilever... without shifting left or right.

Then it seems be very tricky to adjust the cartridge alignment without messing up overhang/distance.

I'm tring to walk away from the table every time I find myself thinking "Screw it - this has to be good enough and much better than how it was previously setup". I don't think I would have this discipline if it weren't for all the rave reviews here, so thanks guys.
I brought another light into the equation this morning and realized that I wasn't as accurate with Step A as I thought... so I started over. Every time I think I had it, I walked away and came back fresh a half hour later. If it looked good I moved on, otherwise adjusted again.

Step B is a pain - I'd adjust alignment to find I screwed up overhang. And step B seems a little more 'subjective' than step A.

Anyhow, was finally satisfied with step B and declared myself finished. :-)
Well, it's hard to say exactly and here's why: I changed cartridges, so it's not like I can truly judge the sound difference to be a result of the tractor setup. Also have to consider that a new cart needs to break in.

Additionally, I ran out of my 'personal time' and am now sort of on 'family time', meaning I can't do any critical listening just yet. But I am playing an LP over and over, running downstairs to re-start it every so often (trying to accelerate break in of the new Dynavector 20XL) and my first impressions are that it sounds *very * good....
