Silver does not oxidize so much as it tarnishes, by picking up sulfur

I once watched a guy build a 1KW linear out of surplus parts. He had this
beautiful silver-plated tank coil, and this idiot SAMDPAPERED the tarnish
off!

Can you say "skin effect", boys and girls? ;-)

It could have been solid Silver.

Also, Silver plated wire DOES have favorable skin effect, sanded or
not. Tarnished Silver wire would not be as favorable.

Can you say get a grip on what skin effect is?

Ever heard of "surface area"?

Him abrading the less than 1/10th of one mil tarnish off with an
abrasive does NOT reduce the size of the wire by ANY amount that would be
measurable in the setting it was being used in.

The coil will do the job it is designed for in either case.

At 100% of its original efficiancy?

At most "hand made radio" frequencies... yes. And the term is
efficiency. It comes from the word efficient. There is no word
"efficiant".
