Tangential to the ongoing discussion, might someone tell me when the 
transition to plastic wire came about?  I find that these sets are 
infinitely easier to troubleshoot and trace issues and that components 
are (surprise...surprise...) relatively in-spec.  I find few resistors 
way out in "plastic wire" units that are found in good physical 
condition.  It may well be that its _all_ attributable to age.   Still, 
there is a clear transition....
