Jim,
All kidding aside, one of the worst nightmares for anyone dealing with
solid-state equipment today is the lightning hit. I don't mean the kind
where smoke and flame comes out of the equipment and sets the building on
fire, but the kind where apparently nothing happens. A friend of mine who's
the chief engineer at a TV station in Connecticut used to complain
constantly that about two weeks after even the most minor electrical storm
some piece of equipment would fail, usually in a manner that was difficult
to troubleshoot and fix. While I can't say for certain that your speech
chip is that kind of failure, my point is that it doesn't take much to send
a chip south, and it may have been something as simple as a static pulse, or
a voltage spike. One nice thing about tube-type equipment was that you
could beat on it all day and it wouldn't fail. Unfortunately, solid-state
stuff is much less forgiving.
Steve
