From the post
And since this is a circuit that is popular mod platform, here is the layout with component numbers that matches the factory schematic so you can easily identify which component to sub when following mod suggestions online.
EDIT! 201217 Elijah-Baley have created a great mod sheet! LINK! So now you can socket the whole board and modify it to your taste. :o)
