Why is the AR XA headshell made of plastic?
I'm puzzled at why this supposedly amazing turntable would come with a
tonearm that used a plastic headshell. Considering that plastic perhaps vibrates less than metal could that be a reason? Any thoughts? Nicole. |

I paid $79.95 for mine. The tone arm also lacks other features of modern tone arms, such as a two point bearing gimbal in the horizontal plane, an antiskate adjustment, and a cueing mechanism. All this was sacrificed for economy. The platter/motor adjustment rates much higher on the scale of things, which is the principle reason for the endearing popularity of this piece. At your salary per film, I would think you could afford a better table . |

Plastic headshells weren't that unusual in inexpensive turntables and changers of the day. Considering that plastic perhaps vibrates less than metal could that be a reason? Any thoughts? The plastic headshell was the least of the AR turntable's tonearm problems. Leading issues related to friction both horizontally and vertically. The arm was sorta competent at 2 grams tracking force and above, but quite incompetent below 1.5 grams. When it was introduced it was marginal, but as cartridge technology advanced it became problematical. |

The vertical wasn't too bad, because it has a gimbal. You could call it that. There were two bearings composed of hardened steel points in glass sockets. If you adjusted them right and didn't crack the glass, then it was OK. The horizontal is actually a large ball bearing with far too much friction. The ball was the thrust bearing, but there was a long sleeve bearing as well. And you're right, most mistracking was due to excess horizontal resistance. I could get it to track at 1 gram, but at the time Shure had ultra-low tracking force cartridges, which were not compatible. I owned two AR TTs, and had friends who also had them. IME, YMMV. |
