I never seen anyone write in about this. I’ve had several break over the years… a couple on my Aoyama Etude (’89), and one on my LH15 (’71).
Once I bought a new disc from Aoyama…took two tries to get the right one.
This time, I did what I did with my LH…just switched a disc I don’t use (B# or E#) with the broken one. I will try to get the replacement so I’ll have it for the next one that breaks.
So I’m wondering if anyone else has experienced a disc arm breaking. Fortunately, mine have happened during practice, not during performance.
