Greetings,
I need to use a large number of banana sockets for a patchbay. Rather
than buying these by the hundred, I find that I can buy hard brass
tube of the correct internal diameter for a few cents. Now collegues
have told me that I must have these plated with nickel or similar to
get a good contact, but I recall the patchbays used for low level
microphone signals used in recording studios were often unplated
brass, and no care was ever taken to clean them, in fact they were
often filthy with a black greasy deposit. Also scientific and
laboratory instruments up to the 20's were made with unplated brass
terminals.
What do people think, could I get away with unplated brass? My
application is for patching low level dc voltages in the range +/-10V.
Regards
TomH
