What kind of noise?

I had a high-pitched noise that increased in intensity and then almost (or
completely) went away, with a perior of a few seconds, and you a Whelen
unit.

It appeared and worsened over the years.

The problem was a bad electrolytic capacitor inside the power supply. Of
course, the power supply was too old for Whelen to service it, so we
drilled out the rivets; replaced the power supply; and reriveted the box
closed. It worked fine for another five years, and is now starting to make
the same sound again. Probably another capacitor.

Cost was about $2.98 for the capacitor and about $0.30 for rivets. It took
about thirty minutes to make the mod (but longer to get the information
g).
