Okay, I finally figured it out. After removing the bottom of the turntable to get to the motor, I found that you need a really small screwdriver to actually get all the way into the hole and turn the potentiometer. I’m not sure what the exact size is, though I think a precision screwdriver that’s a few inches long will fit through the bottom of the turntable. I’ve got it all dialed in now, and it works perfectly! Thanks for the video, Mike.
The directions in this guide work for the PS-LX310BT and the spindle assembly replacement part works with it as well. I can confirm this, I ordered a replacement spindle assembly because mine was bent and it worked perfectly.
