Yes, thank you Chris.
The head-shell on the AR arm looks identical to the one on my Systemdek arm which, taken together with Mr. Uchida's statement that the head-shell is not Jelco design, implies that AR tonearm is not the variant of an SA250-ST as was previously thought by some. Of course, the differences remains in the center bearing design, the yokes on the AR arm being practically identical to the SA250-ST and the Systemdek ones looking very Linn-like but without the 'top housing' as it were. The antiscate bias housing remains non-Linn.
Who makes the LVX arms for Linn?

Mike
