J | Jacks -[ FAFM '23 ]-

A small pile of RCA jacks (aka phono jacks). This is the same style of jack as the one I photographed about three years ago, but now in two-piece insulators to isolate the jack from a metal chassis.

 

LIke I mentioned in the earlier post, the gold plating is a corrosion-resistant coating for improved performance, an important consideration for a connector originally developed in the 1930s (the part the plug mates with, not the mounting configuration).
