It was lost in post and came after about 2 months. I think it got damaged in the process because the channel balance was off about 7db. Maybe the coils got out of alignment.
if one channel level is 7dB lower than the other one then there is a problem with coils but if there is a 7dB difference between channel separations of left and right then it’s ok. I don’t think anything is wrong with the cartridge as long as lower one is over 20dB.
trying to align azimuth according to channel separation readings whether using AM or Fozgometer may mislead you. simply don’t bother matching those numbers but try to achieve the highest possible separation on both channels. for example 20dB LR and 22dB RL is worse than 25dB LR and 30dB RL.
the problem behind that anomaly is record surface flatness. records are not flat, almost all of them. if you don’t have a vacuum hold down option on your record player it’s almost impossible to achieve a perfect flat record surface and matched channel separation levels.
I measured azimuth on many turntables and the only ones achieve flat record surface are vacuum hold down ones. I even moved the arm and cartridge to a no vacuum turntable but I couldn’t get same matching-azimuth numbers which I get on vacuum turntables. and I tried this on a couple of no vacuum turntables too with no luck. unfortunately I’m using a turntable without a vacuum hold down. I tried some mats and weights but none manage to fix it like vacuum. maybe there is a solution without vacuum but I have not yet encountered it. I tried different test records too. for example on turntables without vacuum different test records give different numbers based on where the azimuth track is located on the record. but you get exactly same numbers on turntables with vacuum.
additionally and more importantly matching channel separation levels on azimuth tracks only align the coils but doesn’t do anything about stylus being perpendicular in the groove which is more important, but that’s another topic.
anyway IMHO it’s hard to say anything about the coils’ alignment if you are not measuring on a turntable with vacuum.
