TM848 repair?

[Jim Brain via cctalk]

Anyone on list repair or rehab Tandon TM848 drives?  I have a 4 or so of 
the slimline drives from some Tandy Model 12/16b units that don't seem 
to spin at all, and I've hooked them up to the same PSU that a TM848E 
successfully runs on, so I am guessing it's not a PSU issue. (Though, my 
understanding of 8" drives is extremely minimal, so...)

If I could get just 2 of them working, that'd put a few 12/16b units 
back in operation.

Jim
