Genuine Sansui audio RCA (Cinch) terminals, gold plated, used, one piece ("A" or "B")!

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 marked in blue circuit, and it will become normal RCA Terminal.

Those RCA (Cinch) terminals in the background those gold plated are just as an example of how those terminals can be significantly corrected after so many years in use.
