Another case of cartridge spec not agreeing with actual product

（中文在後）Another case where the spec does not agree with the actual product. When the top of the cartridge is near level, the cantilever is close to 30 degrees, quite far from 23. Though given the angle between the contact line and cantilever is close to 120 rather than the more common 110 degrees, the SRA still ends up just slightly higher than 90.

又一個規格與實際不符的情況。當唱頭上緣接近水平時，針桿角度約30度，遠高於23。但還好它的線／桿夾角在120度左右，所以此時SRA只比90度高一些。
