cartridge setup help

Actually what would be ideal is to use a nut that will fit such that it cannot move in the little square cut out under the screw hole, that way you can tighten down into it nice and easy. So if none of the nuts you have are suitable maybe go out a look for a slightly bigger one

a bag of cartridge screws/bolts can be easily secured from E-bay or Amazon.  Get the right size or the setup is wrong.

Anyone want to give it a try for $100?

It's worth the drive to Pasadena, to have Brian Berdan at Audio Elements correctly install and perfectly align the cartridge.
