Level issue
When I level the table I find it's hard to get the platter exact.

The platter is glass and has soft rubber (?) mat.

When I level by making the platter depth to table .5mm all the way around
the bubble is half in/out of the circle where the stylus lands.

What I can do is set it so the area where the stylus lands is level - but
the bubble is off at the opposite end. How should I leave it?


You seem to be implying a situation where your platter is not planar.
That would be a very bad thing. Try leveling with the mat removed.
Maybe its got some variance that affects the small surface area those
little bubble levels occupy. Also try a larger level, I use a 6"
contractors
level...place it in front of the spindle then rotate the plate 90" to get
both axis. I've never had it read not level in another location
on a platter once one location was level in both dimensions.

Anti-skate issue

Using the HFN test record i get excellent results using the 15db tracks
(not the 16db - but I hear most people don't?)

When I use the anti-skate (I think it's a Jelco arm) it doesn't seem to do
much unless I am at the extremes. (The 15db track tells me this -
buzzing). my thought was that the adjustment is crude and I am good to
go? Is there something I am missing?


Haven't had to mess with antiskate since I went linear. sorry.

Michael Fremer helped me. Turns out some platters are slightly concave.
using a record did the trick
