Cart not parallel after Mint LP alignment?

Howdy,

So after reading about 1000 paragraphs on how good the Mint LP Tractor is - I purchased one and had a marathon session yesterday with my new SL-1210 M5G, AT440MLa and Zupreme headshell...

After all was said and done - the alignment itself took 90 hard minutes - I am finding the cartridge sitting about 5-7 degrees "right" of center. The actual cantilever and stylus are about as dead on as I wanna go with it for now.

Now a comment and a question....

Question: Is this non-parallel result in the headshell normal? It's making me think I may have a bent cantilever or something.

Comment: I have run 10-12 sides thru the rig so far and I must say - I have not yet heard the "revelation" that others have described when comparing their alignments to other protractors or even the white Technics alignment gauge. The rig sounds good...but...what I am missing here.

I must temper the above by saying I have changed phono stages frequently in the last month as well...I was getting nicely familiar with a Bellari VP-130 and then moved that for a Cambridge which lasted less than a week and I now have a Moon LP3 with maybe 25 hours on it...Even my AT440MLa might have 40-50 hours on it as well....

I am thinking that a whole bunch of stuff might need to "burn" in before the system starts to really reveal itself.

But I am very concerned with the stylus/cantilever on the cart...even with all the moves the Mint required...I expected the cartridge to sit straight in the headshell...perhaps expecting too much?

Appreciate any feedback.

Cheers!

By the way, I agree with Tvad's very first post: If the cantilever is indeed bent a bit then that accounts for the "problem" you note, which is not per se a problem in fact.

I love the MintLP tractor, and have bought one for every tonearm I have owned, and they do make a difference. That said, the difference is really based on how close you came to getting the geometry correct on your initial set up.

With my current rig, I found that the I had VERY little adjustment to do at all when I got the MintLP. When I set the cartridge down on the mirror the first time, it was about dead on from setting it up with the VPI jig that came with the turntable.

Thanks guys - for all the responses.

As far as I can see with my eye - the cantilever is straight - however - without a precise measurement - and I must admit - my eyes were ready to pop out - how can I be absolutely sure? I will assume a precision product like the AT440MLa does in fact ship with a straight cantilever.

But - with the Zupreme and the lame screw set included with the AT...nothing like those tiny round nuts to drive me crazy - I probably didn't have the cart perfectly parallel to begin with and as the movement back and forth continues with the Mint - it ends up being "off".

If it's normal - I can live with it for now. The AT is fine piece but I am also considering an upgrade to the 2M Bronze shortly...with it's threaded body...I believe it will be much easier to get a tighter grip on the headshell and ultimately finer more precise movements against the Mint.

For you folks using the nuts/screws method...is it better to use the round nut or a hex that will "grab" against the cart body and provide a tighter "tighten".

For the record - my Mint - is specifically designed for this table. This was my first use of it and I am sure subsequent runs should be more precise.

Appreciate anything else that you can add.

Cheers!
