Tonearm Noise


Hi. I am curious if anyone can tell me if it's normal to hear a loud noise when lowering or lifting the tonearm. The sound my tonearm makes is similar to a mike being tapped or dragged, however, once the stylus hits the record its very quiet. Do I need to apply lubricant or oil to it to reduce friction, I've read somewhere here that doing so will create more problems because oil or lube will attract dust. if it helps my TT is a Nottingham Interspace Jr with a Interspace arm. Thanks.

Is this noise from the tonearm itself or through the speakers?

I never raise or lower my toneram unless the "mute" is on or the volume control is all the way down.
Thanks for your response Mofi. It's coming through the speakers. I turn down the volume now but I didn't really have to before. I forgot to mentiion eralier that sometimes I can hear the whir of the platter specially on a 180 gram record. I added a capful of oil from NAS to the spindle and cleaned the entire table and tonearm which improved things a little.
Does it happen at both the inner and outer groove when you lift/lower the tonearm? If so, at the same level?

My thinking is that the cartridge or arm is picking up some kind of EMI or RFI maybe from the motor or improper grounding of the internal tonearm wiring. Maybe just try moving the interconnects around or try a different grounding location.
