Jdfelice,
The 6.2 is a full function preamp, so you should be hearing music. Take it off of the straightwire setting, if you have it there, and see if you hear anything. Double check the cable connections on the preamp, too. If that doesn't get anything for you, maybe the connection on bottom of the turntable isn't making up. That Dual has RCA connections underneath on a little board, so that they are disconnected when the tonearm is lifted. That is actually where I suspect the problem lies. If so, it shouldn't be that hard to correct.
Best,
Win
