You need a stereo with "TURNTABLE" input. Newer stereos don't have it and the turntable input is especially made for amplifying the small input voltage from the turntable. Then... connect computer to an output LINE level, (not speaker output). Now you will have some problems with HUM coming from this setup. You can solve that problem by doing 2 things. 1st be sure the GROUND wire from the turntable is connected to chassis of the stereo. 2nd, you may need to use a GROUND ISOLATION RCA cords. They have tiny isolation transformers inside a little plastic case. It keeps ground of the computer from touching ground of the stereo. This will completely eliminate any HUM and now you can use the computer (audacity etc) to record from the turntable. The picture is a sample of a typical isolation transformer with RCA plugs. Those are the things I do to record albums to my computer.
