Is analog supposed to be so noisy?

I am experimenting with a Luxman TT which is actually in pretty good shape. My system consists of the Prima Luna Prologue pre-amp and the Prologue 6 monoblocks. A phono input was installed in the preamp when I bought the units. As soon as I turn the knob to the phono input, I am bombarded with a fairly significant hum, which is not present when I use the settings for my CD players. Is this something normal, or am I doing something wrong? By the way, I have also tried my old Moscode Minuet in A, which includes a grounding plug for the turntable, and I am still getting the same problem.

Did you check the cartridge connections to make sure they are secure and correctly installed? Then check the ground on your tonearm cable to make sure the ground is not broken.
To me it sounds like something in the arm is causing the problem. A broken pin or wire perhaps.

I would also check underneat the turntable to make sure the wiring is good. The last table I had like that I rewired the tonearm with better interconnect and it was a huge improvement. You also need to look at areas underneath that need lubricating. Is the grounding scheme on the TT okay? That's where I would start. I don't feel it's your preamp.
