Embases RCA Cuivre Pur Plaqué Rhodium (La paire)

Fine connector but hard to solder
This is a good quality connector BUT, very hard to solder and the plastic isolators are not the same quality as the metal connector.
Chep PVC plastic or something like that, this connector need a lot of heat to solder and the plastic do not tolerate the amount of heat. If you can, solder them before you mount them.

good, hard to solder
Need a massive amount of heat to solder the outer ring

Fair priced, good offer!
I really like the sockets, for sure a good deal.

What I don't like are the isolator plastic shims, they are just to flimsy and hard to fit (11 mm drill required). I got not a good feeling with them.
I went with rubber rings instead that are normally used for cable through case installation.
