C28 Phono Level Problem

Just picked up a C28 preamp and MC2105 power amp, and everything is working great other than the phono level input of the C28. There is a constant hum/static noise in the left channel when either of the phono level inputs are selected, and the volume must be turned to maximum to hear the volume at any type of listenable level. I'm thinking that there is a problem with the C28 because the turntable and cart were working without a problem earlier in the week with my Pioneer SX-950. Any help would be much appreciated. Also, what would be the best way to clean the connections for the knobs on the top? Thanks, other than this problem, I'm loving my new setup!

Swap the phono leads at the C28, if the problem remains in the same channel the C28 probably has a transistor out, if it moves with the lead it's the turntable or cable.
