Technics 1200 tonearm sloping down
For a while now I've been dealing with one of my Technics 1200 mkii3d's having a tonearm that slopes down from back to front. The needle is pointing downward not drastically but noticeably. I need to adjust the vertical azimuth by +2 in order for the tip of the needle on this deck to be level with the same needle on my normal looking deck.
Could anyone recommend what might be causing this and how I could try to fix it?
