I am selling here genuine Sansui audio RCA (Cinch) terminals, gold plated, never used!
As you can see on the pictures, those RCA audio terminals are special versions made by Sansui, central pin (HOT) is shorted to the ground when there is no any Cinch plug connected to the terminal, but when you connect cinch plug to this connector, central pin will be disconnected from ground of device.
That is very good option for example, phono input in Sansui amplifiers. If you don’t need that option, you can just cut contact, and it will become normal RCA Terminal.

Maybe it's the last chance to get never used gold plated RCA audio connector for yours premium Sansui amplifier.
