No, I haven't figured it out yet, truthfully I haven't even fooled with it any longer. I moved it to the garage, I am remodeling my music room (paint, hardwood floors, base boards etc etc). So once all of that is completed I will move the organ in and figure it out. I have found several manuals that break down how to fix them. I have no clue why technicians charge so much to work on Hammonds, after closely reviewing the internals of my C-3 it is truly 1950's technology, it isn't hard to figure out or work on at all. So I will be fixing mine myself. I'm also on vacation, so that adds another delay.
