      A/C compressor noise?

      OK...I have a 73 Z28 which has vintage air a/c. We took it for a drive today and it started making a noise. At first I thought it was in the tranny. It sounds like something rattling, almost like a throw out bearing that is not aligned with the shaft if that makes any sense. This only occurs at 2k rpms and above. The a/c works great but the noise is driving me crazy. I am 99% sure it is the compressor (which is brand new Sanden from VA) since the noise disappears when the a/c is shut off and doesnt happen again unless you turn on the a/c. Has anyone else had this problem? Is it normal noise for these compressors? (I wouldn't think so but it is my first VA unit)
