It's been a few years since I posted on here, so long I couldn't remember my username and had to create a new one.  With the help from people on this website, I put together a little starter system back when I just got out of college.  After a few years of moving around for work, the stereo got left in boxes waiting for me to find a more permanent dwelling.  Well this weekend I unpacked the stereo and was going to listen to some albums.  Unfortunately I am having some problems

 

i have: denon dp500m turntable, connected to pro-ject phono box 2, connected to jolida jd202. PSB image b25 speakers. Ortofon 2m blue mm cartridge.

 

when I turn the amp to the channel the turntable is hooked to, I get a fairly loud humming sound?  If I select a different source like iPod, the sound is fine.  So I am getting some feedback from either the turntable or the pre-amp right?  I made sure the project is on the moving magnet setting.  If I play an album, I hear the music but the humming is still very noticeable. I checked the RCA connections, they are tight.  Any ideas on what else I could be checking? Do I need to take it to a repair shop? Has one of my components bit the dust?

 

thanks in advance for your help!
