Buzzing sound emanating from my speakers when receiver is set to 'phono'

What turntable, cartridge and ohono preamp are you using. This may shed a little more light on the problem. 

Thanks again guys!

:thumbsup:

My table is a Techincs 1500

And the receiver is a Denon dra-550 from the mid 80's

Cartridge is an ortofon blue.

TIA

There's a ground lug on the back of the Technics and one on the back of the Denon.  Do you have a wire connecting them?  If not, that's likely you're problem.

If that doesn't solve it, the Ortofon may not be properly wired or have a loose pin connection:
