cartridge setup help


Was wondering if anyone near Las Vegas with cartridge setup experience? I purchased a used AT150MLX for my friend, but we can't seem to get a firm screw connection in the open channel. Would be willing to pay for help.

a bag of cartridge screws/bolts can be easily secured from E-bay or Amazon.  Get the right size or the setup is wrong.
It's worth the drive to Pasadena, to have Brian Berdan at Audio Elements correctly install and perfectly align the cartridge.
I live in Henderson,  I use a AT150MLX and I have a bit of experience.  Email me at allan.walter@yahoo.com and I'll shoot you my phone number.  Also I don't want your money, It's the season of giving!

The problem description is not clear. What do you mean with

''the screw connection in the open channel'' ? ''Open channel''

make no sense by whatever cart. There is left and right channel

by any stereo cart but not ''open channel''.
