Subject: Help: 8" SA-851 Failure. Where to send for repair?

Problems.

My S-100 work has just come to an abrupt halt by the failure of both
Shugart 851 8" floppy drives.  One lost head #2 (the head that is on
the head-load lever) some time ago, the other lost it two days ago.

I find that if apply a light pressure on the heads then I can boot the
system.. but this is obviously non-optimal.

Questions:

       * I need references to repair places.  Where have YOU sent
         8" drives for repair?

       * Does anyone have a manual for this series drive that has a
         description of all the jumpers and what they do?  Maybe an
         OEM manual with schematics?

YOUR help is greatly appreciated.
