I have a vintage Technics turntable SL-J1. Due to a power surge, the transformer is dead (I'm no electronics tech, but I get 110v ac at the input posts and nothing at the output posts). The transformer has numbers printed on it, but no output voltage, so I can't attempt to replace it. Also can't find Technics factory website to try and find additional info. #'s on transformer are: P48U5 W SLT48DTL4D 521W (If that helps). Any help would be greatly appreciated as I love this TT, and don't want to replace it with something else. "Technics DC Servo Automatic Turntable System SL-J1"
