Last night I installed my new AT 440MLa. It was the first time I ever installed a new cartridge, and I didn't have any guidance from an experienced helper. My tracking force is set to 1.7 (1.0-1.8 is the recommended range) and the anti-skate is set to about the same. I played 4 records, and while two played wonderfully, the two others were constantly crackling throughout (very noticeable). Any ideas on what could be causing this? Thanks for your help guys.
