New drive belt?
I'm dusting off my old AR Cambridge turntable to record my old vinyl
onto my computer hard drive. As I haven't used my turntable for about 8 years is it worth me buying a new drive belt? I just ask because I wonder if over time it stretches/perishes. I've got a new stylus as my old one was wearing out anyway. Everything else looks ok but I haven't got it up and running yet. |

If it is worn out, flattened, or stretched, it will slip or you will hear "wow" (wavering of sustained notes). If neither of these are evident, you are fine. |

New drive belt?
Beware oil from your hands. As I recall AR asked that their belt be clean
and dusted with talc. Wylie Williams "Harry Lavo" wrote in message news:vRUIc.45628$WX.38760@attbi_s51... "Sandman" wrote in message news:vXTIc.69133$%_6.48378@attbi_s01...

If the belt is still providing adequate traction and has not taken a "set" on the motor pulley, it should be OK. Remove it and just let it rest lightly on a table top. See if the rubber has taken a set where it rested around the motor pulley. If so, try running the turntable overnight and see if that gets the anomaly out. If not...if it retains an "impression" of the motor pulley...replace it. |

As I recall AR asked that their belt be clean and dusted with talc. =================== I wish I could remember for sure, but back in the recesses of the memory is the statement by a representative of a then-independent Acoustic Research, Inc., when the AR-XA was the current model of the turntable. He visited our store and, among other things, said that the talc on the belt was to allow a controlled slipping action of the motor when its speed differed from that of the platter at startup, to let it get up to synchronous speed without stalling as it tried to start the medium-mass platter. It was a very low-torque motor, in a day when other-make turntables, particularly "automatic turntables," had big, high-torque motors, and high-traction idler wheels in a drive configuration which wedged that idler wheel between the motor shaft and platter rim. If one inverted the outer platter of an AR on the inner one, and watched it start, one could definitely see the slippage between motor and belt at startup. The motor would reach synchronism almost instantly but the belt and platter would take several seconds to "catch up" smoothly. Ever the experimenter, I tried observing startup after cleaning all the talc off and reinstalling the belt, and did see a "chattering" occur between motor pulley and belt at startup, so the motor was probably going in and out of synchronism while this was happening. As the speeds finally stabilized anyway, I couldn't say it made any difference in the final reproduction. |

My suggestion would be to run the TT for at least 24 hours, then check it for flutter using a piano or organ recording. If you like the results, record away! Norm Strong |

Rubber deteriorates with time and not using it has probably allowed the belt to become brittle. BTW, I found that it's a lot cheaper to take your old belt to an electronics store and let them match it up for you than to order one especially made for your table. I paid two-thirds less buying a belt from an electronics store than ordering it. |
