i wonder if you can help. i have just bought a beogram 3300 and noticed that there only seems to be 5 prongs in the din plug but it looks like there are 2 missing. I have plugged it into my Beosystem 2500 (attached to BeoLab 4500 speakers ) and there is no sound coming out. Can you advise me if i need a separate pre amp as I don't understand whats going on. Really appreciate your help.
