Dave, Of all things, the external supply of the SP10 MkII is likely to be most repairable. The only possible problem I can think of is that some of the ss devices used therein may be no longer in production, but in most cases there should be modern available devices that can do the same job. Otherwise, it's just a bunch of caps, resistors, etc. Most folks are empirically replacing the electrolytic caps in the PS, just because they are inevitably more than 20 years old, if no previous repair has been done. However, if the motor is kaput, then the table is kaput.
