This plug is indeed gold, well it's gold coloured anyway. In this case I think 
it was probably a problem with dirt or grease on the contacts inside the 
recorder rather than wearing of the plug, but I wonder how long till the gold 
layer will wear through. It doesn't get used anywhere near as much as I'd like 
to, so perhaps quite a long time.
