Help with hookup

I did check the mute button, and it was off. I have the speakers coming out of the amp not the preamp. I didn't see that it could come from preamp.

Well I have output main on preamp going to main balance inputs and speaker output 4 ohm to speaker

Thanks! You have given me some things to try. The needles do move on both pieces when on. And I can hear through the headphones. 

Here is what I checked-
Set on balanced and stereo.
Speaker cable is a u shaped audio zen cable, not bare wires.
Input is Dvd on preamp and selected that input.
Tried pushing tape moniter button several times. 
It did work very well, but he had been sick for about a year and didn't use it then. 
Using with CD player. Maybe it doesn't like The Temptations? 
Mute button not pushed on. 
I appreciate so much all the help and ideas!  We will keep trying .

 P.s.- you guys and girls are truly the best!

Hmm. Ok, I have a Audio Space tube amp I can try. I have to have to get it out to take pics of it to list it anyway and I know it works. Or maybe the Sony,it works too and is much lighter.  I can't believe I didn't just do that first. DUH. We are going to figure it out. Thanks for your expertise!

So, this morning when I was trying some things I found that when I had it hooked up to CDR the tuner on CDR and I turned it all the way up I could hear music in the amplifier but not the speaker,. So I tried to change out the cord to the speaker and that didn't make a difference. I will try different speakers and see if that is the problem and check the output terminals to see if they have something coming out of them. Sorry I don't know all the fancy words, but I think you get my drift. As always, thanks for any advice that you have!
