Chakster, I own Technics SL 1000,mk 2 with Obsidan plinth
but removed the mediocre original feet and put AT pneumatic
636 footers instead. The plinth is actually a frame (not guitar
box) like Lew's slate plints. The armbase is according to me
also suitable for 12'' tonearms. I use (10'') FR-64 s and there
is sufficient room on the armbase for an larger arm. Waht kind of
''Obsidian plinth'' are you referring to?
