Damn thought I might have to do that, I wasn't looking forward to the prospect though as I don't trust my soldering skills on a board, I'll probably fry the damn thing.

When I purchase replacement FET's how do I know if they are logic level driven? (Please excuse my ignorance). Edit - Im Guessing something like IRL540N is logic driven because of the "L" in the name?

I have read the suggestion before of relocating the board, but it sounds like a lot of messing around.
