ZW-44 Built, However got a Severe Buzz???

[koa-dogg]

I built the ZW-44 and it Sounds Really Good, However there is a severe buzz. Turning the pots down lowers the noise but it is still there. Any suggestions what this could be? Bad Ground? Cold Solder? Any help to point me in the right direction would be very much appreciated! I tried different MPSA14's and different op amps but the buzz remained.

By the way any, suggestions on a good sounding OpAmp? I tried one of the brown Burr Op's and a JRC4558 and I thing I like the JRC4558 best.

Thanks,
Scott

Bad ground.

Thanks for the tip. I will check my grounds again tomoroow. I kind of felt it was a ground thig but wasn't sure.
