I'm just assuming its the preamp because that's your variable. We have a very similar issue with someone who purchased a "Refab" table from the 80's. We hooked it up to a Rolls preamp with a significant hum. We are bringing out a Parasound preamp to test. I'm hoping I don't have to tell him his $100 turn table needs to be replaced....because that won't go over well.
