        Hi Bob,
Thanks for the info ... these are 3380 "E" models. Smoked plastic cover
over an AL casting. I assume the magnets & actuators must be in the ends
of the drive housing. Haven't had a chance to look at them yet. I can
imagine a head crash on those would have been something! Still can't get
over the size of the drive motor!
