I know a few folks that custom make parts and many are from DEC if anyone needs
me to check just let me know.

That one is a standard outer dimension alright, but electrically
it's plain odd. 35V 70Hz AC or something. It runs from a full-H
circuit from the (possibly battery packed) 36V supply. Ther

They are frozen up pretty bad. I heard from another list member here they

The DEC fans that are now a few decades past end of life the bearing wear out.
Nemonix Engineering has made (new not refurbished) fans that are sealed so they
do not dry out. Something to keep in mind - one of the things I remember was
that as the fan slows down (prior to full death) since the
