GOLDRING LENCO L70 TURNTABLE

HI.DOES ANYONE OUT THERE KNOW HOW TO CHANGE THE TONEARM BALANCE ON ONE OF THE DECKS?IT APPERAS THERE ARE TWO SPRINGS INSIDE THE BACK OF THE TONEARM PULLING THE WEIGHT INTO THE ARM ALL I CAN SEE IS TO TAKE THESE SPRINGS OFF AND THE WEIGHT ON THE ARM WILL SLIDE BACK.DOES ANYONE KNOW IF I REMOVE THE SPRINGS THIS WILL WORK? THIS BEAST TRACKS AT 15 GRAMS THE ARM NOW IS VERY HEAVY I AM USING A SURE V15 MK 3 CARTRIDGE AND THE STYLUS GOES INTO THE BODY WHEN TRYING TO PLAY A RECORD.
ALSO ANYONE KNOW THE CORRECT WIRING SEQUENCE TO TURN THIS LITTLE DEVIL INTO 240V FROM 110V? I WOULD BE VERY GRATEFUL GUYS.REGARDS.MIKE
