And, don't forget relay contacts. Vacuum relays are usually ok, but any
crack in the glass or ceramic obviously could be a problem. And, self
cleaning contacts may be probably ok. But plain old contacts watch out and
clean them periodically.
With the coax connectors, provided they are properly soldered, it can help
to clean them and apply a thin coat of electrical grease like Penetrox to
keep the oxides away. This of course does nothing for the cheapies,
especially the right angles, that just plane burn up at a few hundred watts.

I second that. Used RF Connection for years.

I recommend the RF Connection <http://therfc.com>. They sell both junk
and the good stuff (not just Amphenol, but other ones they have dug
into). you can get junk from them, but if you ask they will steer you
right, and the prices should be your guide. I asked one time why they
carried junk, and the reply was simple - "hams want cheap."

Perhaps.
I would also look for bad connections that are the result of junk
connectors or badly soldered connectors.
99% of all connectors sold at hamfests, and even by most dealers selling
to hams, are JUNK, and they can cause exactly this sort of problem that
is hard to find. This may sound biased, but it is not. If a coax
connector does not say Amphenol on it, or if it is not a vintage
connector with a UG number (military surplus) it is almost certainly
TRASH. This advice also applies to barrel (splicer) connectors, Tees,
Elbows, and adapters from one connector type to another.
REAL connectors cost about twice as much as the junk, and you have to
look for the good vendors that sell them. That's an extra buck or two
for each connector. But how much did it cost you to sell one rig and buy
a new one? And your problem is still there. :)
