Hi to all,
got a number of Speakon connectors yesterday that have solder pins on the back for PCB mounting. Unfortunately, they must be very old stock and the once shiny silver plating has gone very dull and brownish - naturally they are not easy to solder.
What is the best way to remove the ( silver sulphide ) tarnish and make the pins solder friendly again ??
BTW:
I am using old fashioned 60/40 " Savbit " five core solder.
