Mac Color Classic, Performa LC 575 | CRT Alignment Tool ToTs RETRO CRT Alignment Tool for The Mac Color Classic, Mac Color Classic II, LC 520,550,575 and Performa 575 and similar As I was performing my first Color Mystic 640x480 mod, I could not locate the tools needed to adjust the CRT. So I made some. Here is a 2.0mm Hex Non-Conductive Tool needed to align your CRT. Kit includes 2 so you can adjust multiple settings at the same time without the need for constant removal. This was designed for use on the Mac Color Classic, and Color Classic II also works for any LC/Performa 520,550,575 line up and the Apple Color Plus 14? Display. May work with more. If your monitor has the 2mm hex size, this will work for you. This alignment tool was made to be used with the back monitor/computer cover off to gain access to the CRT adjustment points. each kit includes 2 units Blue Handle Grey Hex shaft These designed have been tested and have the perfect strength and fit to get the job done well.
