What type of cartridge is in your tone arm?
I'll assume that it is magnetic.......if so, there are still some very high quality ceramic cartridges available that produce a high enough signal level to be used in a normal low-impedance amp input, such as that for a CD player. You may be able to get by simply changing the cartridge......
Shure makes one, if I remember correctly, that is made specifically for your application (I can't remember the model, but I'll try to find it) You will need to rebalance and re-track the tone arm, but that is easy, depending on the make/model of the turntable.
