I am going by memory as I owned a Premier Mk2 back in 1987. The Premier offered a higher level of fit and finish. The biggest difference was the sub chassis which had greater mass with a larger footprint for stability. The arm board is also larger and could accommodate a greater range of tone arms. The MK2 had a DC motor with an outboard power supply that also provided power filtering. The suspension pillars and design are the same as the Delphi as the maintenance kit for each table is interchangeable.
The biggest difference between the various Mk1, Mk2 etc was the motor used. In the early days, Oracle had motor supply problems that necessitated a change in motors. Not sure about the bearing but I was under the impression that they were the same as the Delphi, but I could be wrong.
They are nice tables that can be upgraded by Oracle. Some of the motors used on earlier Delphi and Premiers are no longer available, therefore, that could present a problem if a motor repair is required. There is also a company that polishes Oracles to a brilliant mirror like shine that make them look like a mega buck table.
From a sonic point of view, the Premier addressed one of the problems of the Delphi. The Premier does not have a lean bass character like the Delphi, and that is what sold me on the Premier. Sorry that I dont have any more specific details, but I would look in my files/manuals for additional info and post if I find anything.
