Seem to have licked it, yeah. I still haven't got the spring scale to verify the pinch roller pressure is right.
Since the last post I bought an MS-16 from the first owner - I moved the 85-16 to my friend's studio to cut live tracks there, since it's frustrating to try and overdub yourself on (no track remote and no automatic sync/input switching). MS-16 came with all of the manuals.
I'm planning to modify it so I can select 7.5/15/30 ips - just for special tape speed effects, I'm aware that the EQ won't be correct on anything but 15. I'll be sure and take some pics and post them here when I get around to doing that
