Good proposal to connect 200wpc. If this solves problem, it exonerates the TT and front end.
@whyduhitme Starting again here. You don't get the fuzz on other inputs than phono. So try a different phono amp as I note the MA252 has no MC input. I don't see why changing the phono amp prevents you plugging into the line level inputs on the MA252 as you do now. I assume you get equal fuzz in both channels? Check the settings on the Mofo are suitable for the cart.
