Measet,
The bearing oil on the RX-5000 should be replaced with a good low viscosity turbine oil, Zoomspark works well. When opening the bearing you will notice there is a steel thrust plate that will have a dimple on it, you can flip around and use the other surface if you wish. The ball is white ceramic which I replaced with a Silicon Nitride ball (that is also an option). Replace the O-ring seal. The rebuild has to be done by someone that is experienced.
The electrolytic capacitors in the motor control boards should be replaced as some of them will eventually fail causing speed problems, remember these components are more than 30 years old. The motor itself should be cleaned and lubricated. This also should be performed by someone qualified.
Performing these steps should extent the life of the turntable for a long time.
I am working on a power supply upgrade for the motor, initial results are promising but it will take several months to complete.Rerurn to Romy the Cat's Site
