[ARC5] roller inductors

[Michael Hanz]

An intelligent young lady by the name of Bobbi Barmore on the old 
Boatanchors reflector did some extensive tests on silver polish for 
roller inductors because she was chief engineer of a broadcast station.  
Under microscopic analysis, the "quick" solutions like the wipes and 
Tarn-X etched thousands of microscopic holes into the silver layer, and 
guess what?  It then/enhanced/ the action of atmospheric sulfides on the 
surface of the wires because of significantly increased area exposed to 
the air.  Switching to a cream based polish solved the problem.  You 
might get quick results with the quick methods, but you have set the 
stage for eventual failure.  I've never had that problem with Hagerty's 
or the other high quality silver polishes, and I have checked with a 
microscope more than once since then.

Jus' sayin...
