Okay a friend of mine up in vegas runs a magnum s9 with the 1969 finals in it and man oh man does it sound AWESOME!! so i go to look to buy one and all i can find is the mosfet final version witch after owning a galaxy dx98vhp that had mosfets in the amp and in the radio i told myself no more mosfet radio's that radio blew up on my 3 times and the third time smoke was just pouring out, so is a mosfet magnum s9 safe to use? or should i hunt down a 1969 final version of the radio? also where can i find one?
