Rega P5 Hum


I don't listen to vinyl much these days, after having rediscovered it a few years ago. I think that the improvements in Digital over the last 5 years (particularly in DACs) have greatly closed any gap between analog and digital.
One of the reasons that I don't much listen to my vinyl rig is that it has become a pain in the ass. My Rega P5 table has developed a massive hum that seems resistant to every other change I make in the system. the p5 doesn't (I should say didn't--it has been discontinued) come with a ground wire. Supposedly the ground is contained within the wires from the tonearm to the phono preamp. If it did have a seperate ground wire, I might be able to get rid of this noise.
Any suggestions?

Don't know what to tell you-but there must be something wrong with your P5-I've owned several Rega tables over the years, none of them came with a ground wire, and none of them had any hum whatsoever. You don't by any chance have a Grado cartridge? I have heard that some Grados hum on Rega turntables.
