This posting is more of an update. I pulled the old W9INN down for
inspection and found a crack in the PVC. It was interesting to note the
imprint on the top of the center conductor (not a balun) says W2AU;
however, it does not look like a W2AU on any web page. It has ground
strap running from top to bottom. To make a long story short, the
crack in top of the device was easily repaired using PVC cement and
it passed all continuity tests. It is back in place and working FB.
