Could be something other than the needle too...
Does it only happen with some records?
If so try this...
Get a mirror and and a good strong flashlight. Open up the machine while an affected record is playing. Put it into service mode, kill the power or whatever you have to do to stop the turntable from spinning.
Now use the mirror to inspect the needles contact point on the record and the bottom edge of the needle/cartridge assembly. You may have to spin the platter by hand a little. Look for physical contact between the two.
I've seen some instances where the raised outer edges on some records will actually touch the bottom edge of the needle and/or cartridge. This contact will transmit vibrations through the pick up and out of your speakers. Usually sounds like a light scraping noise and it typically goes away after the first 30 seconds of the record.
I once had a Rowe R series machine where on the bottom edge of the cartridge actually had a spot on it where the black paint had worn bare from rubbing on the records. The fix was to adjust the cartridge angle with a shim placed under the mounting bracket. Be advised, you'll also have to adjust the tracking force and anti-skating settings after an adjustment like that.
If a new needle doesn't fix it for you I'll try to get a photo of what I am talking about. Might explain things better than I can.
