Capacitor List

There is a capacitor list inside the service manual. However, they list all caps including non-electrolytic caps which don't usually need to be replaced. I've gone through my 29E31S-16 board and grabbed the values off the capacitors manually for my own capacitor swap. There is a total of 63 capacitors with 13 on the neckboard.
