I will just add that I sold my Linn (approx 2016) it wasn't used due to me living abroad, but did later purchase a PT and then a Lenco, both of which I enjoyed more than the LP12, mainly due to the fact I was able to listen to a larger range of music. Looking back I tended to only play those albums that sounded great on the Linn.
I'm going to bet your LP12 had a Linn arm and probably an Ittok because that's what does that. It is not a characteristic of the deck itself. At least it wasn't back then.
