Welcome on board Josh. Yes there are a some engineers here, plus others deeply experienced in repair & building. As for cloning a Knucklehead, please don't go diving in the deep end. Get some experience building simple amps first, see if you want to continue. It would be awful to gather a big expensive pile of parts then discover you're not as enthusiastic when the mammoth task begins. It is good that you have some experience building instruments, but it's quite another thing to build amps especially very complex ones like the KH.
