    Sony PS-X70 Wobbly Speed 33/45rpm

    Hopefully someone can help me out here. There's a 'wobble' in the speed (both 33 and 45rpm). I started measuring the voltages on the power supply and there's only one value completely off Q406 64.4V instead of 35V. Perhaps someone can give me some pointers what might be wrong?
