I am selling genuine Sansui RCA (Cinch) audio terminals, NOS, never used!

As shown in the photos, these RCA terminals are a special version made by Sansui. On the back side of connector, half of that connector is grey and other half is black. BTW just as info…RCA Sansui connectors without grounded central pin is black on the back side of connector, and with grounded central pin, those Sansui connectors is grey on the back side of connector.

The central pin (HOT) on the grey part is internally connected to ground when no Cinch plug is inserted. Once a Cinch plug is connected, the central pin is automatically disconnected from the device ground.

This feature is particularly useful for applications such as phono inputs in Sansui amplifiers.

If you do not need this function, you can simply cut the contact marked in blue in the circuit, and the connector will function as a standard RCA terminal or buy another type RCA Sansui terminal which doesn’t has central pin grounded

This may be one of the last chances to obtain unused original RCA connectors for your premium Sansui amplifier.
