Im currently working on two projects one xtant 1001dx and an 603x. I already have a working 1001dx that I reference to repair the project one, I just need someone who has a working 603x to list the mosfets and transistors going down the line from left to right or right to left or however they would prefer. I've been searching and can not find any information about this anywhere. I contacted xtant and they said send it in and the will not disclose schematics due to trade secrets which is understanding. Any help is greatly appreciated and I am very thankful.
