Maybe we should arrange a vat of this stuff and arrange to have our radios
dipped in it, as that seems to be the cause of a large number, maybe a
majority, of the problems we see discussed. Every now and then a part has
failed, not often, but these contact corrosion problems seem to be ubiquitous.
When I had what ended up being a $300 round trip to Sevierville, Paul told me
this was more common after the switch to some standard, RoHS or something like
that.
My DX-40, National receiver, Galaxy V, SB101, FT101 and Drake C-line radios and
every linear amplifier I have used never had a single problem, all the way back
to the Eisenhower Administration. I do not recall ever hearing of one back
then either.
