I have the PF-800 turntable and I absolutely love it. I have had it for 4 years. It looks and sounds fantastic. Lately I have been thinking about doing some routine maintenance to ensure its running in tip top shape. Of the serviceable parts, I wanted to look at the motor and maybe oil it. While the turntable has no audible motor noise or hum coming through the speakers, I can hear the motor "whirring" when I get about 2-4 inches from the motor. None of it makes it through the belt, platter and into the speakers. My question is, how do I oil this motor? Does it even need it? is leaving it along the best thing to do? last thing I want is to mess up a motor for which there would be no obvious replacements! appreciate any insight or experience with this turntable.
