RAMM Audio 30891RT - RCA plugs

This is one of the few RCA connectors (perhaps the only one except the Bullets which however follow a somewhat contrasting philosophy) built entirely with this material.
Copper (99.5%) tellurium (0.5%) is an extraordinary alloy for this use. It maintains practically the same conductivity of copper but makes the mechanical processing of the copper much easier, therefore the stress of the metal is enormously reduced. It also has a nano-crystalline structure, composed of copper telluride particles of minimum size and uniformly distributed, very close in appearance to the OFHC.

After processing, it is completely deoxidized by the action of phosphorus, and immediately covered with a very thin sheet of Silver and then rhodium to prevent oxidation without altering its conductivity characteristics.

The manufacturer of this connector is the same as the now famous cables which are having a phenomenal success. The maximum inlet diameter is 9.9mm, the advice is to solder with solder inclues silver.
