I used to have an AR turntable, about 10 years ago. The only problem
I had with it was the lubrication in the vertical arm bearing dried
out and stiffened up. There were only sleeve type bearings in this 
unit, nothing esoteric like ball or jeweled bearing surfaces. The 
original oil was a tacky high viscosity goo to provide a measure
of damping for the arm, I replaced it with a more modern silicone
based product with good results. I added an outboard Benjimin
Miracord cuing device to raise and lower the arm, (I don't think this
is available any more), and eventually replaced the belt and platter
cushion. There is no provision for anti skate on the old model. I
had a Stanton 681 EE cartridge mounted in the shell(I still have
it and like very much). I don't recall where the arm resonance was
but remember that I did have a nasty acoustic feedback problem with
a cartridge with a more compliant stylus. Anyway, I beleive the 
fellow I sold it to is still using it. I still have my AR amplifier
and after replacing some of the dried out aluminum coupling caps
with tantalum ones, still sounds good.
