Sorry - not a SME. All I did was mounting a FR-66s 12" tonearm on a Super Scoutmaster w/2 (two) HRX motor drives, double isolated platter (sandwich construction 4" high) isolated by liquid and spindle from bearing) and mounting dome w/MS clone armboard.
It works.
Nice.
Much better than expected.
The 1" mounting hole for the standard VPI tonearm is an invitation to have a dome made which can accommodate the many different Micro Seiki armboards (and their clones) around. Thus you can use virtually ANY tonearm on the SSM.
Done here only to test a few technical ideas and set-ups as part of designing routine for a new turntable.
