I don't know what you have, so I'm guessing, but there is probably a
pre-amp stage. Whether it's in the turntable, the receiver or the amp,
I don't know. There just has to be one in there...

Just wondering....Have you given the amp a really thorough visual inspection?
The reason I ask is because the older the original kit, the greater the likelihood
that there may be some degradation...
