I've only recently figured out the proper set-up of my TT. it requires patience, confidence & a really steady hand.
You can print out a decent protractor @
www.enjoythemusic.com just cut out the spindle hole and it should give a decent template for adjusting the cartridge to the tonearm.
For proper tracking force VTF, Shure makes a $25 scale that works good or a plastic digital one from ebay will cost the same.
For another cheap cartr alignment protractor, check out
www.garagearecords.com. its $1.
On my TT the enjoythemusic one sounds better...
the hardest part of this for me was removing the cartr clips without adding pressure on the tonearm. Get a nice small needle nose pliers, not the heavy one normally found at Home Depot. finding the right force and technique here is key, and once you're comfotable the addest confidence makes the other adjustments easy.
