Help with hookup

It's getting to the point when you really need to try to borrow from someone or somewhere a power amp, to swop into the system.  If it works with the replacement, then the guilty party is likely the power amp you have; if it still doesn't work, then that points to the preamp.

Do you have a multi-meter? If you do then put the leads on the speaker posts and see if you get a reading . With music playing the meter will fluctuate!

The puzzling thing about all of this is, the power amp meters are responding to the signal from the preamp, so, the amp is receiving signal. It needs to be at the power amp, somewhere, or, the speakers themselves. I am with twoleftears and yogiboy, on this one....

ide hook a different amp (even an integrated if you don't have another power amp)to the speakers or different speakers to the amp to see which is not performing. my guess is either the connection between the power amp and speakers or the power amp itself. the preamp (and the link to the power amp)is good since the power amp gets signal and there is sound through headphones.

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!
