That's great news! Seeing as you have the old arm (with the old wire) VPI's suggestion of twisting the wire 1 turn may work wonders for your tracking. Just undo the connector where it goes into the RCA junction box and turn it 1 turn. One direction will make it better, the other worse. I don't remember wich way though but I think you want to go clockwise. If you upgrade to the 9 Signature arm it comes with the anti-skate device and is a better arm with better wire. The twisting is too much with the thicker wire(dielectric)in the Sig arm. IMO.
PS- Get a Mint Protractor and do you own set-up. Very rewarding!
Disclaimer-I'll be selling my Mint shortly as I have a new arm coming for my TT. BTW-I ordered a new Mint for the new arm ;-)
