[ARC5] roller inductors

[Dennis Monticelli]

Interesting.  I think that's another reason to finish any cleaning with the
ProGold.  It will take care of those microscopic pores.  I have an ARC-5
transmitter coil that was removed and cleaned and thoroughly rinsed and
then thinly coated with the ProGold.  It's been 11 years and still looking
and working great.

BTW, the plating on certain keys is so thin it's like a flash.  I too have
seen nickel go down to brass with almost no wiping with a product like
TarnX.  I have not seen that occur on silver plated surfaces that are
intended to take the wear of rollers.  But I don't leave the silver cream
or the DeOxit on for long.

As they say "test in an inconspicuous place first"
