Nifty thread, lots of good info about al oxide, etc.
OK -- some 15 or more years ago I set up a hi-fi system:
the receiver/amp/fm-am were, as usual, in one box,
and I connected it (via cables) to a tape deck
and (later) to cd-player (my terminology!).
When I did this the cable ends were "male" aluminum,
and on the various boxes the "female" sockets(?)
were also aluminum (seemed to me. Maybe it just
*looked* like aluminum?)
Anyway, the other day it was sounding a bit "scratchy",
and it turned out to be cable-connection. After I
got my pocket-knife and lightly scraped the male plug,
it worked fine again.
Someone observing this told me that times had changed,
and that these days pretty much no one used aluminum;
instead, they used gold-plated plugs and sockets, etc.
That I throw away all my (stereo) cables and replace them
all with these gold ones.
So here I am considering this, wondering how much these
new gold-plated things will cost, etc --
and lo and behold, I come across this thread.
QUESTION: once you had scraped clean an al plug,
then would you paint on one of the several anti-oxidation
products you were talking about?
Or maybe that makes no sense at all!
