Thanks to the many who responded.  Before calling Kenwood for a replacement
fan unit (abt $25 I'm told) I tried a drop or two of sewing machine oil.
There is no oil hole
on mine so I gravity fed the stuff down the shaft (sic).  Whatever ... it
works and is
quiet, at least for the moment.

Thanks to several for clearing up the mystery of the little brass widgit
that rubs on the motor shaft.  My 930 is a very late model - S/N 8M plus -
and had the device already
installed.  for those who haven't run into this, it appears the motor needs
a sideways
load to run quietly (they were designed to run a load via a belt and
pulleys) and the spring provides that.  Part or all of my noise may, in fact
have been due to the fan brushing the spring, because when I first
reinstalled it, the fan was rubbing really badly - I discovered that by
sliding it out the shaft a little bit the interference was removed and
everything sounds fine now.
