Ortofon headshells are known for this, possibly because their headshells are designed for their own cartridges. I had issues trying to install a Hana into one. Ended up breaking a clip. I solved the issue by removing the leads and replacing them with ones that actually fit the cartridge.
Help with cartridge wire clips
Finally got all the parts for my Michell Gyro SE. Trying to put it together tonight, and the clips for the tonearm (Michell Tecnoarm II) are too small for the cartridge's pins (Hana ML). Looking around online I found usually the clips have a slit, or multiple for the round ones, so you can expand them for the pins. There are no slits in these clips, and I am at a loss as to what I am missing here. I also tried my Denon DL-160, same thing though. The manual only mentions making sure the wire color matches the pin, nothing else. Does anyone know anything about these arms?
