Evomod,
I am also having trouble understanding this circuit. I just need to understand how the 4 new FETS are connected/wired to getter on the new board. the pictures arn't doing me any justice. Im thinking on IC6 and IC5 do you wire S1 to D1 and than S2 to D2 Im not sure whare any of the G's go

Some help from neurokinetik or LithiumXmod would be nice.
