Is it one of the AS tonearms with the one point headshell connection? Like the WTB313? https://goo.gl/images/NUGojx
If so it could simply be that the connection point was loose and the headshell twisted. On most tonearms you couldn’t change the orientation of the cartridge that much without severe damage but with this design you may have gotten lucky. Have you tried playing an LP (with volume low?)
