Morning Robert, Do you have a spare headshell for your PL-5? I always recommend having a spare or two so that cart swapout is quick, safe and easy. Regardless, you'll want to follow cart mounting instructions in the owners manual. If, for some reason, I didn't send you one let me know with an email address and I'll shoot the instructions to you. Secondly, break-in - give the new stylus 20 or so hours to break-in. You'll be pleased with the results. Any questions whatsoever, drop me a line here or to my email: beej1123j@aol.com.
