These connectors are made from bronze, gold plated. The wires are silver plated, TEFLON isolated. Designed for connecting the CARTRIDGE YC-02 to non-Yamamoto Head shells. The diameter to connect to the head shell is 1.0mm. The diameter to connect to the cartridge is 1.2mm. Do not reverse wires, or the 1.0mm connector will damage.
