Cartridge, Phono Preamp Hum

I just installed the same cart in my set up with no hum. Try borrowing another phono-preamp to see if that's the problem...

Same thing happened to me about a year ago on a different set-up, except the left channel didn't work. Changed cables, switched cables, substituted different phono stage. Then I took the cartridge out, blew some compressed air over it, and reinstalled it. Have never had a problem since then. Was probably some dust (or perhaps the stereo gods were punishing me.) Try it. Might be that simple.

Turns out a ground wire from phono pre wrapped around one leg of the table then hooked to the input of the table speed controller has done the trick. No kidding.
