Is your image centred?


I am giving up on my old Analog rig soon!
The image on most of my disk is not centred! Some shifted to the left, some shifted to the right!! Yet, some are dead centred!!! WHY???
My rig:
Thorens 125 mark2
SME 2009R
Otofon MC20 Super, Grado Prestige Gold

Wow, So many replies! Thanks.
I am interested to hear that other people have the same problem. I tried with the azimuth and seemed to correct it a bit, but still not centred. Also, all of these happened with vocals and rock & rock albums, They are old LPs of the seventies and eighties. In my memories, they were not that bad but my systems were not as good at the time.
I was thinking that it might have to do with the the rig losing its tracking ability? Well, would a more expensive tonarm or cartridge do a better job better or worst???
Antiskate is almost literally in these cases like a balance knob... I have heard it on the fly while an album plays as my table will allow for it and I can pan left and right like sitting in a car with the fader or balance knob! But again this is very difficult to adjust unless you have a table with an actual device built into the arm to do so, many just have a fishing line with a lead weight hanging off the back of the arm...

I have found the lower the antiskate gram weight the more to the left the image shifts, the higher the skate in grams the more to the right it pulls... Could be opposite on some tables but I doubt it.

To say the least I thought I had some really in-balanced classic rock and new albums especially some of the beatles and zeppelins, now 99% of anything I throw on the table after finding the correct antiskate have played pretty much dead on equal DB from each channel.
Have you tried a mono LP? Now, that should be centered image. Use a simple production, uncomplicated one, such a a single voice or instrument. There are also test records for center channel.
