Another Request for Information/Knowledge

What are some possible reasons for distortion in both channels following a cartridge swap? I used a basic pvc protractor and positioned the cartridge correctly at both null points and I set tracking force and anti-skate at the recommended settings for the cartridge. The cartridge is a rebuilt Yamaha MC-3 with a boron cantilever and a fresh re-tip both done by Namika in Japan. The arm is the stock dual tube arm on my Yamaha PF-800 turntable.

I am getting distortion from both channels that is most audible during soft passages.


I wasn’t sure how to use the protractor to account for overhang. As luck would have it, the original overhang gauge that came with the table is the one accessory missing from the box.  Could this account for the distortion?


I’ve learned a lot about vinyl playback over the past couple of months by reading through many discussions posted here but I may be in over my head with my first cartridge swap lol. Thanks again to all who who have helped me along the way.
