Hi, didn't have time to check all replies, but first check for
a broken glue joint on dust cap...those can buzz at certain frequencies.
Well just remove it and check for buzz again. If buzz gone, re-glue cap
done deal.
If buzz still present, you can inspect the cone/bobbin joint. Those are
known to come loose...use epoxy. Also look for any contact of
the bobbin on the pole piece while moving the cone. Check for
foreign objects.
Next is the spider to cone glue joint. Those can come loose and buzz or click. Epoxy is best here.
Let me know results...
