Thank for taking the time to explain.  I do feel humbled and about three 
inches tall (seriously - for how I feel that is - not the actual 
height).  As for my mistaken belief about gold, you're probably right - 
I must have remembered it wrong.  I hope I did, because my electronics 
teacher I still have a great deal of respect for, so I hope he wasn't 
wrong.  But he was also one of the autoshop teachers with a strong 
streak of mechanic in him, so I think (hope, imagine?) that the issue at 
the time was one of mechanically laying one conductor upon another and 
then I suppose gold provides a good surface for a good connection?  I 
know I recently had trouble with my old DVD player that began paying 
only in black and white.  I pulled out the video connection (S-type) and 
plugged it in and out a few times to clean the contacts, which fixed the 
black and white playback issue and it's been playing in color since 
then.  The cord is a cheap one with pins that have oxidized.  The gold 
coated plugs I have seem to stay in perpetually good condition, which 
reinforced my gold belief.  Now, <sniff>, I'll never be able to look at 
gold the same... <sniff-sniff>.
Thanks again for the enlightenment,
