Strange buzzing from turntable
I have an interesting problem with a Pioneer Pl-630 turntable that I just bought. I have a CJ preamp with no phono stage so I'm using an Emotiva XPS-1 phone pre that has worked very nicely for 2 years. When I plug the turntable's interconnects into the Emotiva and power it up I hear a fairly loud buzz(not a ground-related hum, or hiss). The buzz gets louder when I turn up the volume. When I turn on the turntable the buzz gets more powerful. I can listen to a record but the buzz is prominent.
Today I unplugged the turntable leaving the interconnects in the Emotiva with the Emotiva powered up, and I heard what sounded like a tv station coming through my speakers. My TV and cable box were unplugged. This happened no matter what CJ input I used. I understand this is probably an RFI problem but I have no idea how to remedy this. I used a Project Debut Carbon turntable nearly daily for the past 2 years and did not have this issue. Any thoughts or expertise would be appreciated. Thank you
