Dr. William,
In your case I would recommend that you have a spare fan or two. I
retired two years ago from full time radio broadcast engineering.
Technology has really changed everything. But starting 10 years ago, I
ordered spare fans for every critical item in the broadcast chain. other
engineers in town though i was nuts, but i was the one they called when
they lost a fan. (Markup was usually lunch!). A typical Nautel
transmitter today may have 30+ fans in it. Fans and power supplies. 90%
of broadcast equipment failure is the power supply. I have a KPA-500,
and I am not worried about its power supply. But those wall warts and
even the cheap inside power supplies today are the reason i still get
paid to be on call for stations. But for your piece of mind, I would
have a set of fans on hand.

I use my KPA1500 for contesting... and it's never hot... but I do worry
about the fans wearing out. At one point I asked Elecraft if they had a
"Fan Kit" for it that I could keep in stock here in the Caribbean just in
case one went south in the middle of a contest...
