Lads and Gentlemen,
I'd really appreciate your advice. So, I have a Dual CS 2235Q direct drive record player, which has EDS 910 motor, as shown in the pictures. So, I sometimes have louder and sometimes quieter problem with a buzzing noise, although buzzing sounds are always repeating per rotation, even if I unplug the turntable from the wall, and rotate the platter with a finger. You can hear it from the audio example. I'm not sure what would such a noise depend on, other than static electricity. But, when I first lubricated the spindle bearing, noise was gone. I used SAE 30 mineral oil, which is, apparently, not recommended. Unfortunately, a few days after that, the platter was making squeaky noises, and wasn't moving very freely. But I found out that if I hold the spindle and move it up and down the spindle shaft (not sure what is a better word for it), noise can become very quiet or gone. Also, if I touch the spindle while the platter is rotating, sound becomes even louder. And the other way around, if I touch the tone arm, buzzing sound becomes quieter. What could this mean? One person from Dual turntables repair and parts shop recommended oil shown on the picture, which took me by surprise, since the oil is mineral. Isn't synthetic oil a better option? People can't seem to agree about turntables lubrication, and, unfortunately, my record player's manual doesn't say anything about oils, just the other way around, that "the turntable should never be lubricated". Some people advise on using "sewing machine oil", but that one seems to be very thin. So, my concern is how will any type of oil be evenly distributed from the bottom to the top of the spindle in a shaft (since there is gravity in my country)? Do I need some type of grease, so it won't just fall to the bottom of the spindle? Also, there is a metal pin touching the spindle all the time (I drew a red arrow pointing at it). What is it for and should the spindle be lubricated where the pin is touching it?
