If the armboard is already drilled correctly for the arm, the ET tonearm can be set up successfully with the plastic cartridge alignment card that came with the arm (a clear rectangular piece of plastic with a hole at one end to fit over the turntable spindle and a scribed line along its length), an allen wrench (or two) and a six inch level. A small machinist square (3") to set the post is useful, but not required.
ET made a jig for setting up the arm, but it is not required, just makes it a bit quicker. You just need to step through the process logically and methodically starting with the turntable being level. If you spend some time with the manual understanding the configuration of the arm, and the interaction of the various adjustable components, you can move through it one step at a time and be successful. Just remember that all of the adjustments interact and that the desired outcome is for the arm tube to be level and tangential to the radius of the record.
