mmf-5 arm adjustment

That's the trouble with MMF. You realy can't.
If Regas can go away with arm-spacers(to increase VTA), for MMF can't tell you if it will work.
To decrease VTA you can use plastic spacers between cartridge and armshell thus playing between margins of tracking force and sort-of VTA.

You can adjust the VTA on the MMF-5 by loosening the 2 screws on the base of the arm using the allen-wrench that came with the table. You can then lift or lower the arm as needed.

Thanks for the response Deedar, but do you know if there's any way to adjust the horizontal alignment of the cartridge?
