I have done a bit of PS and output section swapping in my day. I have to say though, you can not really double your output by changing little things. You have to change a lot. Such as the main power transformer(s) and the mosfets, then modify the controller so that the SMPS action is set to stop charging at a different voltage via changing the divider network being one way. It really is fun to tinker with an amp that you don't really care about. Though be careful, they are indeed lethal, especially when you get a considerate amount of filter capacitors on there.
