Please exercise caution when working on your 1200's. They are delicate and can be broken if things are forced or pushed the wrong way. Do not do this work unless you feel confident in yourself, and of course I am not responsible in any way for any damage you may inflict on your equipement. Everything in here I have done myself and works on my own equipment so if these instructions are followed carefully I can see no reason why they would not work for you as well.
On to the good stuff. I've browsed the web and was unable to find any information on how to change the colors of your 1200's from Red to Blue, so this is the force that has driven this web page. I am going to add other jobs such as changing the RCA cables, the power cable, the pitch control, the braking, and finally tuning procedures. But since this all takes time it will have to wait. There is other documents on the web that describe most of that but nothing about LED's, so enjoy.
