AR ES–1 Problem.... Suggestions

Often, it is the motor, not the bearing. Take off the belt and turn the motor on. If you hear the grinding it's the motor. Likewise, remove the belt and with the motor off spin the platter by hand. If you hear the grinding, it's the bearing. Two more tests. While the platter is spinning, if it spins for a long time with a continuous, unimpeded motion then it is probably fine. If you have a record with a silent groove play it at high volume and listen to the rumble, if it is not prominent then the bearing is fine. A lead-in or lead-out groove can be used for the rumble test but ya gotta be quick. If it's the motor AR had some for sale last year so they probably still do. If it's the bearing give them a call and they may have a new one.

Above are all very good tests. You may also contact Underground sound in Memphis TN. They are old time AR tweekers and offer info, repair, parts ect.

Mr. Merrill has retired a short while ago and I don't know if you can now get a whole lot from Underground Sound for AR tts. It may be worth a try, but don't hold your breath. Plenty of info available at AA on the mother of all suspended tts. A number of companies have replacement motors. I believe the original was manufactured by Hurst (won't swear to that though) and they are still available from them. Good luck and don't ditch that cd player!

I did some trouble shooting before posting and did the things that Viridian suggests. The brushing–grinding is in the bearing, seat area. There is another problem though which is motor related. Even while the unit is off the motor trembles-vibrates(to the touch). When on the platter turns at the right speed but the vibration while off troubles me even though I don't know weather it adds rumble during play.Thanks for all your help and any more suggestions for a remedy or as to whom to contact for information would be appreciated.
