I just bought a Technics TT yesterday. Still in the original box, still in the originally packaging. Never used.

I just connected it to the phono input on my preamp, and when I tried to play a record, no sound was getting through to the speakers. I usually play my music through my computer, so I know its not a problem with the power amp.

Can anyone give me any clue to what might be wrong/how I can fix it?

Thanks.
