I keep anywhere from 6 to 12 of these relays in my parts bin. It is most
common for the relay coil to open.

Why trepidation? It's common for connector contacts to oxidize or become
loose over the years. Disconnecting and reconnecting one or more times
simply scrapes a bit of the oxidation off. Just be careful to remove and
re-connect them without bending contacts, and lined up correctly (not one
row off, for example). And do this for ALL the connectors.
Another thing I would try is to back off the power a lot (5-10W) and see
if you get anything out. If the SWR is very high at the rig, the TX may go
into protect mode, especially at full power.
I think this may be a job for Sevierville.
Why? It's probably one of the first things the guy on the bench is going
to do, and I'll bet that you work a lot cheaper than he does, especially
by the time Paul Clinton is done with you. If these simple things don't
fix it, THEN send it to them.
