Rob, why not rebuild it. There are 2 capacitors, and 2 transistors that should
be replaced. The capacitor is generally the culprit, and you can often times
see the crack in this part.
It is cheap insurance, and takes about 2 hours total time to do, including
R&R. I have done 6 for myself and friends, and its no big deal. Go to the
United site or STOA, where there is an excellent article on the issue.
I went with adding a separate wire to eliminate the white wire pickup, and this
is also covered in an article.
